Providing protection from particles, water, oils, and liquids while allowing pressure equalization in micro-environments, the company’s vented screws suit applications that include sensors, protective cases, lighting enclosures, general enclosures, and appliances. The screw vent meets IP67 for particle and water ingress and its cap will not separate from the body during installation or application. It is comprised of automotive-grade plastic that is resistant to chemicals, solvents, and high temperatures. The screw vent houses one of a number of different filter media choices including hydrophobic and oleophobic media, which are puncture resistant and protected from moisture. A hex nut is also available upon request. Donaldson Company Inc., Bloomington, MN. (952) 887-3874.
