Protective vents prevents the ingression of a variety of contaminants, such as water, dust and other particles while allowing water vapor molecules to diffuse through the microporous membrane.
Equalize pressure and reduce condensation by allowing airflow into and out of sealed enclosures.
With an IP68 protection class (water depth 2 meters / 60 mins) and -40℃ ~ +125℃ operating temperature range, it can be used in harsh environmental conditions.
PMF-6B works up to 2 liters capacity enclosures. Whereas, PMF-12 models work for up to 5 liters and PMF-12HS models work for up to 50 liters.
Larger PMF-32 is also available.
For outdoor use, more efficient to install on the side(s). Recommended to use for industrial, electric, electronics purpose only.
