2. Dust collector - Wikipedia

   en.wikipedia.org/wiki/Dust_collector

   Two rooftop dust collectors in Pristina, Kosovo. A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas. Designed to handle high-volume dust loads, a dust collector system consists of a blower, dust filter, a filter-cleaning system ...

3. Residual-current device - Wikipedia

   en.wikipedia.org/wiki/Residual-current_device

   A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...

4. Micromotor - Wikipedia

   en.wikipedia.org/wiki/Micromotor

   These micromotors actually propel themselves in a specific direction autonomously when placed in a chemical solution. There are many different micromotor types operating under a host of mechanisms. Easily the most important examples are biological motors such as bacteria and any other self-propelled cells.

5. Fractional-horsepower motor - Wikipedia

   en.wikipedia.org/wiki/Fractional-horsepower_motor

   Servo motors and stepper motors are specialist types of fractional-horsepower electric motors usually intended for high-precision or robotics applications. Usually running from a DC supply, when combined with a planetary gearbox can offer accuracies less than 8 arc-minutes (2 ⁄ 15 ths of a degree, or approx. 2.3 milliradians). Due to their ...

6. Electrostatic precipitator - Wikipedia

   en.wikipedia.org/wiki/Electrostatic_precipitator

   High collection performance due to (1), (2) and (3) Marginal to high: between 2 × 10 10 and 10 12 ohm-cm: Reduced operating voltage and current levels with high spark rates. Significant voltage loss across dust layer. Moderate electrical force component retaining collected dust. Reduced collection performance due to (1) and (2) High: above 10 ...

7. Central vacuum cleaner - Wikipedia

   en.wikipedia.org/wiki/Central_vacuum_cleaner

   This datum is calculated as follows: P = 1/8.5 x F x S where P translates to the power in air watts; F is the airflow in CFM; and S for the water lift in inches. The standard air watt formula is from ASTM International (see document ASTM F558-21). [3] The air watts indicate the motor's global performance, and thus the central vacuum's ...
