The APCDSS6 is a stainless steel pressure compensation plug designed to manage pressure differentials in tightly sealed enclosures. Constructed from machined Type 316L stainless steel for corrosive applications, it operates over a temperature range of -40°C to 80°C. The device features a semipermeable membrane that provides an air permeability of 1,200 liters/hour at a pressure difference of 70 mbar while filtering out contaminants. This plug provides IP66 and NEMA Type 4X protection, making it ideal for applications where slow pressure equalization is required due to heat from internal electronics or ambient temperature fluctuations.
