If one machine is rated in amps and the other in watts, a conversion of the amps specification to watts makes comparison possible but is "apples to apples" only if the motor amps alone are used for this comparison. Dirty air uprights are only rated in amps. The % of vacuum is a relative value where pressure at normal or standard atmosphere is the base value.. p v% = 100% - (p v / p atm) 100% (1). You can hide the blocks you don't need by clicking on the block headline. L'essentiel est de conserver une dépression et un débit d'air … Power Output 500 watts PEP CW/SSB/Data Duty Cycle at 500 Watts 10 minutes key down / 5 minutes standby Drive Power 30 to 40 watts for 500 watts output La consommation d’énergie s’exprime en kilowatt-heure. Then, a complex formula was applied to come up with a Peak Horsepower rating. When the fans spin, a partial vacuum is created and the pressure inside the vacuum cleaner drops below the ambient (or existing) air pressure in the room. To switch the unit simply find the one you want on the page These include filtration, cleaning tools (agitation), capacity, quality, noise, features and cost. Otherwise this site will not work Therefore, amp ratings give us a means of comparing the input power of a vacuum motor and the vacuum cleaner as a whole and are a meaningful specification for comparison purposes. The pascal (symbol: Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength.The unit, named after Blaise Pascal, is defined as one newton per square metre and is equivalent to 10 barye (Ba) in the CGS system. Next, you need to consider whether the vacuum cleaner you're considering has all or most of the features that you need for effective and pleasant cleaning. Consider your cleaning situation and be sure that the vacuum cleaner you choose gives you everything to make the chore of vacuuming as easy as possible. In uprights with this design, only filtered or completely clean room air passes through the motor in order to cool it. Contact: Ms Tanja Demšar tanja.demsar@domel.com +386 4 51 17 206 La puissance utile d'un aspirateur est la combinaison entre la dépression et le débit d'air. Filtration is very important in terms of cleaning ability because HEPA or other advanced filtration increases the resistance within the vacuum cleaner. P (W) = V (V) × I (A). The unit of measurement called standard atmosphere (atm) is defined as 101,325 Pa. But there are also secondary specifications that should be considered before making a final decision. It's absolutely optional. Ideally, the machines being compared will all have motor input power specified in watts for a simple, direct comparison. For more information on HEPA filtration vacuum cleaners, click here. It's your answer. all the rolls can be cutted under customer’s requirements . Elle s'exprime en Watt. To switch the unit simply find the one you want on the page and click it. After all, the more powerful the motor, the greater the pressure differential and therefore the more vacuum suction power and airflow, right? kPa↔cPa 1 kPa = 100000 cPa kPa↔mPa 1 kPa = 1000000 mPa kPa↔uPa 1 kPa = 1000000000 uPa kPa↔N/m2 1 kPa = 1000 N/m2 kPa↔Bar 1 Bar = 100 kPa kPa↔mbar 1 kPa = 10 mbar kPa↔ubar 1 kPa = 10000 ubar kPa↔kgf/m2 1 kPa = 101.971621 kgf/m2 kPa↔kgf/cm2 1 kgf/cm2 = 98.068059233108 kPa kPa↔kgf/mm2 1 kgf/mm2 = 9803.9215686275 kPa On canister vacuum cleaners (with or without power heads) airflow of 100 CFM or more and water lift of 90 inches or more is recommended. Understanding vacuum cleaner specifications is one of the most challenging aspects of selecting a new vacuum cleaner. Voltage within a home is sometimes referred to as "110" and this is because there may be voltage drops through the house wiring. If you have lots of carpet or difficult soils such as pet hair, choose an upright or a power team with a motorized power nozzle. In physics, natural units are physical units of measurement based only on universal physical constants. CFM ratings do not have to be as high as canisters for the same reason. Definition: A kilopascal (symbol: kPa) is a multiple of the pascal (Pa), an SI (International System of Units) derived unit of pressure used to measure internal pressure, Young's modulus, stress, and ultimate tensile strength. Kilopascal : The kilopascal (symbol:kPa) is a non-SI unit for pressure, and is a x1000 multiple of the Pascal unit. [1] [2] It can also be referred to as a measurement of the energy per unit time of the air flowing through an opening, which is related to the energy that electricity carries through the power cable (wattage). The second basic design is one that features a by-pass motor where unfiltered air does not go through the motor. Clique aqui para acessá-la em português. It has 1 kPa = 1000 N/m^2 while 1 Watt = 1J/s = 1 Nm/s. This is the most important specification of all when choosing a vacuum cleaner because airflow is what moves the dirt from surfaces to the dust bag or container. Airflow. Daltons Law states that. This translates to better cleaning ability as the bag fills. For example, a 1400-watt motor converts to 11.67 amps (1400/120=11.67). In the SI system, power is measured in watts (W). p v = absolute pressure (psia, kPa, bar ..). Sign up and save 15% off first order!*. Come visit us The third point of comparison is airflow. It is important not to confuse air watts with airflow, the most important specification of all. Il est basé sur la même mesure que la dépression et débit d’air sur un rendement maximal. converter. kilogram per square centimeter As mentioned in the amps section above, if the only specification available is the amps for the whole machine, a comparison can still be made but it will not be a direct one. After all, just because a motor or vacuum cleaner consumes more electricity, this does not make it a better cleaner. Air Pressure. A year later the technology allowed us to create an instant units conversion service that became the prototype of what you see now. Please make sure JavaScript is not disabled in When installing, allow an additional 2” (5.1 cm) behind the fan and above the top cover for unrestricted air flow. La dépression s’exprime en kPa (en kilos pascals) et elle permet de savoir à quelle vitesse l’aspirateur aspire la poussière. After all, when you do the calculations, an air watt comes to 0.9983 watt or just about the same as an ordinary watt. separated in long numbers: Hope you have made all your conversions I am trying to compare to a eureka that has 48 at the head and 83 "cfm" at the hose end. for you. Autrement dit, il s'agit de la capacité de l'appareil à soulever la poussière et à la porter jusqu'au réservoir. In fact, the challenge of coping with higher resistance is one of the reasons that HEPA filtration vacuum cleaners can cost more. This page is also available in English. The power P in watts (W) is equal to the voltage V in volts (V), times the current I in amps (A):. But here's where it gets tricky. separated in long numbers:Hope you have made all your conversions Otherwise this site will not work 2: Enter the value you want to convert (kilopascal). Therefore, if you see amperage ratings above 12, read the fine print, as they are not true amperage specifications but some other manufacturer developed "performance rating" designed to create the impression of a more powerful vacuum cleaner. Specifications for components such as the motor do not necessarily relate to the performance of the entire vacuum cleaner, and therefore are only a part of the story. 1 watt is equal to 1 joule per second (J/s). Some vacuum cleaners can be so noisy that they're almost unbearable to use. You can have excellent specifications in a poorly constructed vacuum cleaner that will last only a few years, compared to extremely high quality products that will deliver outstanding cleaning performance and will last many years and even decades. There are also a number of other, secondary specifications that influence cleaning ability that we'll also examine. Instant Stress and Pressure Units Conversion. All vacuum cleaners operate based on air flowing from the opening at the cleaning head or tool, through the vacuum cleaner and the bag and/or filter system and then out the exhaust port. reference construction . Noise is also a significant consideration. Then click ... a part of air pressure, depending on its temperature and salinity of the water. 1 mbar = 0.1 kPa: bar: 1bar = 100 kPa: centimetre of water (cm) 1 cm of water = 0.09807 kPa: millimetre of mercury (mmHg) 1 mmHg = 0.1333 kPa: atmospheres (atm) 1 atm = 101.325 kPa: pound per square inch (psi) 1 psi = 6.896 kPa PSI and kPa Converter. In this example, the two motors both have ratings of very close to 10 amps, and therefore, equivalent motor input power. As we have learned, this only measures the electrical consumption of the motor, which is not a measure of cleaning ability. Leave us a question or comment on Facebook . A high-quality vacuum cleaner will often operate at levels that are quite comfortable and will allow you to hear the phone or doorbell ring quite easily. Cliquez pour vous rabattre en français. The definition of a pascal is as follows: The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre. kilopascal to kilogram per square centimeter, kilopascal to tonne per square centimeter, kilopascal to kilonewton per square meter, kilopascal to meganewton per square meter, kilopascal to newton per square centimeter, kilopascal to newton per square millimeter, kilopascal to thousand pounds per square inch, kilopascal to long ton (U.K.) per square inch, kilopascal to long ton (U.K.) per square foot, kilopascal to millimeter of mercury (torr). This is a conversion chart for kilopascal (Metric). tel.+420 571 877 778 . Watts (W) to kilovolt-amps (kVA) calculator. One horsepower is equivalent to 33,000 foot-pounds per minute, or the power required to lift 550 pounds by one foot in one second, and is equivalent to about 746 watts. En prenant la dépression en mmH2O et le débit d’air en litre par seconde du tableau ci-dessous, on obtient 476 air watts. I am wondering how to calculate one to the other. Cleaning ability is not just about vacuum suction power, even though this is an important element of vacuum cleaner performance. The first comparison is watts to watts motor input power. For the best experience on our site, be sure to turn on Javascript in your browser. Comparing machines rated in amps with those rated in watts is not an exact comparison because manufacturers that are using watt ratings typically rate the motor only while amperage ratings use the total electrical consumption of the vacuum cleaner including the motor in the power nozzle (the motorized revolving brush cleaning head), light bulb, etc. 220 car tyre pressure meaning Inside the car door, the tyre pressure front and back is listed as 220. what pressure would this convert to in the UK? Thankfully, it has been largely done away with as a vacuum cleaner specification. Atmospheric or air pressure is the pressure of air in a given environment. This can make it hard to compare across brands. p atm = absolute presure at normal or … So, if we subtract the amperage used by the power nozzle motor from our 12 amp machine, we come up with 10.5 amps for the motor and light bulb. You can then convert this to watts and have a meaningful comparison. To conserve space on the page some units block may display collapsed. Quality can be partially determined by the length of the warranty as well as the type of materials used, the quality of the fit and finish, how heavy duty the housings are, how tight the seals, how close the tolerances and so on. Again, this specification is meaningless in terms of evaluating the cleaning ability of a vacuum cleaner. But again, they are only part of the story. p t = total pressure (kPa). First and foremost, consumers want vacuum cleaners that offer the best cleaning ability. next to it. We have examined the primary specifications that impact cleaning ability. Thinking helps: A 100 watt light bulb has in 1 m and in 10 m distance really always the same 100 watts, which is emitted from the lamp all the time. Click here to view it in English. Now find the unit you want and get the conversion result Does convert-me.com really exist since 1996? The sealed suction of a vacuum cleaner is measured in inches of water lift. Эта страница есть на русском языке. As with everything, better quality usually costs a bit more, but is often worth it in the long run. The power P in watts (W) is equal to the power factor PF times the phase current I in amps (A), times the RMS voltage V in volts (V): The vacuum motor consists of electrical components attached to a fan or multiple fans. Il y a cette page en français. Central vacuum makers, as well as some other vacuum cleaner manufacturers, have been using the air watts specification to attempt to rate the vacuum cleaner's output rather than input power. Water lift is also a measure of a vacuum cleaner's ability to deal with resistance within the vacuum cleaner. This is because the motor will be the biggest consumer of the rated amperage. and enjoyed Convert-me.Com. : 2 Vacuum airflow is by far the most important specification in terms of determining the cleaning ability of a vacuum cleaner. If you want maximum precision, set the number to 9. 1: This is a conversion chart for kilopascal (Metric). The origin of their definition comes only from properties of nature and not from any human construct. Does the page look too crowded with so many units? This is a good specification to compare how well the vacuum cleaner will perform as the bag fills and the filters load, and is especially relevant when choosing high filtration or HEPA filtration vacuum cleaners. Work must be measured in units of force*distance, like Nm or ft lbf. The first is the "Direct Air" or "Dirty Air" design where the dirt passes through the motor prior to any filtration en route to the dust bag. As we saw above, the larger the dust bag, the better the airflow, and therefore, cleaning ability. kPa to PSI = Updated: 7/20/11. A kilopascal is defined as 1,000 Pa, where 1 Pa is defined as the pressure exerted by a 1 newton force applied perpendicularly to an area … the. Extremely quiet vacuum cleaners can operate at decibel levels in the mid-sixties while cleaners in the 70-77 dB range are still very quiet compared to the vacuum cleaner you grew up with. Le rapport idéal entre la dépression et le débit d’air est de 40 kPA / 40 dm3/s. In short, airflow is the best specification that demonstrates cleaning ability. Do you want rounded off figures or scientifically precise ones? For the purposes of understanding vacuum cleaner specifications the only thing about voltage we really need to know is the formula, amps x volts = watts and conversely, watts/volts = amps. A good water lift rating also indicates that a vacuum cleaner will keep performing at high levels as the dust bag or container fills and the filters "load" or gradually fill with fine particulate and become more and more resistant to air passing through. It is important not to confuse air watts with airflow, the most important specification of all. Tenemos esta página en español. There was no JavaScript there and all conversions had to be done on server. If both machines are rated only in amps, a comparison can be made of the electrical consumption of each unit with an assumption that if these are close or equal, the motors are similar in input power. cleaning power (air watts) = 0.117354 × F (ft3/min) × S (pressure in inches of water) Some vacuum cleaners specify their airflow in L/sec.. 1 L = 0.035315 ft3 1/sec = 60/min F = 60 × 0.035315 × airflow (L/sec)> = 2.1189 × airflow (L/sec)> Also some vacuum cleaners use kPa or mbar as vacuum cleaner suction measurement.. 1 pressure in inches of water ≈ 2.49 mbar ⇒ 1 … Donc l’aspirateur de 1250 watts sera plus puissant (18 kpa ) que celui de 1300 watts (12 kpa) et moins gourmand en énergie. Since volts are constant at 120, amps represent a valid comparison of motor input power. First of all, you don't have to change any settings to use the Often referred to as "Peak Horsepower" these ratings were obtained by removing the fans from the vacuum motor and subjecting it to the maximum load possible before the motor burned out. This means that a Power Team (a canister vacuum cleaner with a power nozzle) with a specification of 12 amps might be quite comparable to another Power Team with a 1200-watt motor that converts to only 10 amps. After all, when you do the calculations, an air watt comes to 0.9983 watt or just about the same as an ordinary watt. Again, as mentioned above, when making this comparison, try to get the amp rating of the motor only instead of the entire machine. which is required for the converter to function. Kilopascal. Different motors are designed for different insulation classes and are constructed according to EN 60335-1. The water lift of a vacuum cleaner is another useful indicator of performance in that it is a means of comparing the suction of one motor to another and, generally speaking, the more water lift the better.
