The DA 284 is a passive pressure compensation element designed to equalize temperature-induced pressure differences in enclosures while maintaining IP66 and IPX9K protection. It features a waterproof NBR membrane that prevents condensate formation and allows air exchange at a rate of 1200 l/h at a pressure difference of at least 70 mbar for the M40 variants, or 220 l/h for the M12 variant. Available with V2A or V4A stainless steel housings or nickel-plated aluminum, it mounts with M40 or M12 threads and has dimensions of 7.1 in height, 1.5 in width, and 1.2 in depth for the M40 models, or 0.7 in height, 0.7 in width, and 0.7 in depth for the M12 model. Operating and storage temperatures range from -31 °F to 176 °F.
Pressure differentials in enclosures with a high degree of protection are a result of internal and external temperature changes. In the case of negative pressure or partical vacuum, dust and humidity can enter the enclosure through the door seal. When the air inside the enclosure cools down, condensation may occur because the humidity cannot escape the enclosure. The easy-to-install pressure compensation device DA 284 provides compensation of pressure at a protection degree of IP66. Even with a slight overpressure, a waterproof membrane inside the plug allows the humidity to escape whilst blocking water and dirt from entering the enclosure.
