Bopla Pressure Equalisation Membrane Light Grey 11.0 mm (DAE-D11)

Enclosed electronics face pressure differentials caused by temperature changes and altitude shifts, leading to seal stress, condensation, and premature failure. The Bopla DAE-D11 pressure equalization membrane equalizes internal and external pressure while preventing water and dust ingress, extending the life of your enclosures.

Who is it for

Engineers and technicians who design or maintain industrial enclosures, junction boxes, and outdoor electronics that require reliable pressure compensation without compromising protection.
