Vacuum airflow is by far the most important specification in terms of determining the cleaning ability of a vacuum cleaner. In this example, the two motors both have ratings of very close to 10 amps, and therefore, equivalent motor input power. 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. Эта страница есть на русском языке. Contact: Ms Tanja Demšar tanja.demsar@domel.com +386 4 51 17 206 Please make sure JavaScript is not disabled in 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. Cliquez pour vous rabattre en français. The eureka is 1/3 the cost but is it … But here's where it gets tricky. Therefore, it is easier for a vacuum cleaner with normal filtration to accomplish higher airflow ratings. 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. The second comparison will be water lift (sealed suction). 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. Voici quelques définitions importantes : ORIFICE : Diamètre d’orifice d’un appareil. The third point of comparison is airflow. This is because while input power is measured in watts, amps are converted into watts by multiplying by volts. We have examined the primary specifications that impact cleaning ability. The pressure value 27 kPa (kilopascal) in words is "twenty-seven kPa (kilopascal)". This page is also available in English. An upright vacuum cleaner should be around 100 air watts and a cylinder vacuum cleaner needs to be about 220 air watts. p v% = vacuum (%). 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. However, there are a number of primary vacuum cleaner specifications, that when clearly understood, allow consumers to make educated decisions concerning which vacuum cleaner will have the best cleaning ability. JavaScript seems to be disabled in your browser. I am trying to compare to a eureka that has 48 at the head and 83 "cfm" at the hose end. Watts to volts calculator DC volts to watts calculation formula. To conserve space on the page some units block may display collapsed. The first comparison is watts to watts motor input power. 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? Le rapport idéal entre la dépression et le débit d’air est de 40 kPA / 40 dm3/s. Choose how you want to have your digit groups L'essentiel est de conserver une dépression et un débit d'air … Dirty air uprights are only rated in amps. The surface area of the dust bag is also a factor because the more surface area the bag has, the more easily the air will flow through it. There are also a number of other, secondary specifications that influence cleaning ability that we'll also examine. Let's take a look at the primary specifications one by one: The input power of the vacuum motor is measured in watts. The standard air watt formula is from ASTM International (see document ASTM F558 - 13) Where F is the rate of air flow in CFM (Cubic Feet per Minute) and S is the suction capacity expressed as a pressure in units of inches of water. Come visit us Does the page look too crowded with so many units? Tap any unit block header to expand/collapse it. Donc l’aspirateur de 1250 watts sera plus puissant (18 kpa ) que celui de 1300 watts (12 kpa) et moins gourmand en énergie. So, now with airflow rated in CFM and water lift rated in inches, what types of numbers should you be looking for? Try it. [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 primary cleaning tool must be correctly selected because while airflow is what transports those soils to the dust bag, agitation is what dislodges soil from carpeting, flooring and other surfaces. This rating is taken when the motor is totally sealed, and the term refers to how many inches the motor will vertically lift a 1" column of water. For more information on HEPA filtration vacuum cleaners, click here. AC single phase volts to watts calculation formula. The power P in watts (W) is equal to the voltage V in volts (V), times the current I in amps (A):. The service was slow. Since volts are constant at 120, amps represent a valid comparison of motor input power. CFM ratings do not have to be as high as canisters for the same reason. You can view more details on each measurement unit: kPa or PSI The SI derived unit for pressure is the pascal. La puissance utile d'un aspirateur est la combinaison entre la dépression et le débit d'air. Now find the unit you want and get the conversion result So 1 kilopascal = 10 3 pascals.. Does it feature a cord rewind, variable speed controls, on-board tool storage, height adjustable wands, an adequate cleaning radius, the proper tools for your flooring such as a soft brush for your slate entry tiles and so on. 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. Atmospheric or air pressure is the pressure of air in a given environment. Got ideas how to make it better? Again, as mentioned above, when making this comparison, try to get the amp rating of the motor only instead of the entire machine. The origin of their definition comes only from properties of nature and not from any human construct. tel.+420 571 877 778 . Our goal is to make units conversion as easy as possible. Understanding Vacuum Cleaner Specifications. How many kPa in 1 PSI? It also provides some idea of how vacuum cleaners compare in terms of picking up heavier soils such as sand, grit and so on. converter. 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. The amperage rating designates the maximum amount of electrical current used by all of the vacuum cleaner's electrical components when operating. 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. In terms of these primary specifications, there are three elements that are useful in comparing vacuum cleaners. Clique aqui para acessá-la em português. 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 Air Pressure. You can hide the blocks you don't need by clicking on the block headline. As we have learned, this only measures the electrical consumption of the motor, which is not a measure of cleaning ability. Sorry, your browser does not seem to support JavaScript Search or Browse Our Site. In uprights with this design, only filtered or completely clean room air passes through the motor in order to cool it. Vacuum cleaners with more inches of water lift will have an easier time picking up sand and other heavier soils from carpet and flooring. 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). Water lift is what gives a vacuum cleaner the power to pick up or "lift" debris from the floor surface, while airflow then removes it to the dust bag. Understanding vacuum cleaner specifications is one of the most challenging aspects of selecting a new vacuum cleaner. Il y a cette page en français. Upright vacuum cleaners come in a wide variety of configurations, but there are two basic designs. Sorry, we don't know this substance. 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. Essa página também está disponível em português. This is a rating that was used primarily for marketing purposes and had little or no relation to vacuum cleaner performance in the real world. To give you some idea, a conversation at home is rated at 50dB, a garbage disposal at 80 dB and a motorcycle or lawnmower at 100 dB. : 2 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. 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. p t = total pressure (kPa). Do you want rounded off figures or scientifically precise ones? Clicking again will expand the block. Otherwise this site will not work By-pass uprights will usually provide airflow but not water lift specifications and a high performing upright will offer 60 CFM or better. 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. Does convert-me.com really exist since 1996? Watts (W) to kilovolt-amps (kVA) calculator. Airflow is generally measured through the vacuum cleaner without hose or attachments connected. 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. Filtration is very important in terms of cleaning ability because HEPA or other advanced filtration increases the resistance within the vacuum cleaner. kilogram per square centimeter Enter the value you want to convert (kilopascal). A kiloPascal is a measure of pressure, not power or work. The dust bag is also part of the filtration system and a significant factor influencing airflow. 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. Para verla en español haz clic aquí. Please pick one from the list. We assume you are converting between kilopascal and pound/square inch. Pression (the unit of pressure of the S.I is the Pascal): The pressure is a force per unit of area. Cleaning ability is not just about vacuum suction power, even though this is an important element of vacuum cleaner performance. 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. the total pressure exerted by a mixture of gases is the sum of the partial pressures of the individual gases; The total pressure in moist air can therefore be expressed as. e-mail remak@remak.cz So, it is easy to see that the vacuum motor is the heart of a vacuum cleaner. While the ideal comparison is motor input power in watts of Product A compared to motor input power in watts of Product B, some manufacturers do not provide motor input power specifications in the form of watts but instead rate the entire vacuum cleaner in amps. 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. The apparent power S in kilovolt-amps (kVA) is equal to the real power P in watts (W), divided by 1000 times the power factor PF: Watt et Joule. separated in long numbers: Hope you have made all your conversions Therefore, the more airflow, the better the cleaning ability of the vacuum cleaner. After all, when you do the calculations, an air watt comes to 0.9983 watt or just about the same as an ordinary watt.
