IP65 touchscreen display IP65 LED lamp. The IP code or ingress protection code indicates how well a device is protected against water and dust. It is defined by the International Electrotechnical Commission (IEC) under the international standard IEC 60529 [1] which classifies and provides a guideline to the degree of protection provided by mechanical casings and electrical enclosures against ...
The AHAM-certified seal lists a rating for tobacco smoke, pollen, and dust removal, and a rating for room size. The clean air delivery rate (CADR) is a figure of merit that is the cubic feet per minute (CFM) of air that has had all the particles of a given size distribution removed.

Weather-resistant. Protects against falling dirt and windblown dust, against weather hazards such as rain, sleet and snow, and is undamaged by the formation of ice. Used outdoors on ship docks, in construction work, and in tunnels and subways. 3R: As 3, but omits protection against windblown dust. 3S: As 3, but also operable when laden with ice ...
A wiper seal is an axial seal that creates a seal while allowing a reciprocating shaft to pass through the seal's inner bore. Wiper seals are often used for fluid containment and to prevent dirt from entering a reciprocating shaft mechanism.
In mechanical engineering, an end-face mechanical seal (often shortened to mechanical seal) is a type of seal used in rotating equipment, such as pumps, mixers, blowers, and compressors. When a pump operates, the liquid could leak out of the pump between the rotating shaft and the stationary pump casing. Since the shaft rotates, preventing this ...
