Air Compensator

SE-ACM40 Cooling & Ventilation
IP68ePTFE MembraneM40×1.5

The M40×1.5-15 ventilation valve is designed to provide reliable pressure equalisation and ventilation for electrical enclosures, junction boxes, control panels and outdoor equipment. It helps prevent condensation buildup while maintaining enclosure protection and extending the service life of internal components. The ePTFE membrane allows air and moisture vapour to pass while blocking liquid water and contaminants. Manufactured from 304/316 stainless steel with silicone O-ring seal.
