Pressure equalisation elements with a high air flow rate protect sensitive electronics. A temperature drop, for example due to changing weather conditions, can lead to a build-up of negative pressure inside sealed enclosures. As a result, water and dirt may be drawn in through the seals, potentially damaging the electronics.
The pressure equalisation elements feature a metric connection thread. Suitable lock nuts with M12 threads from the OKW portfolio are available for installation inside the enclosures.

Theoretical air flow rate RQ:  10 l/h - 0.07 bar
Water ingress point: > 0.83 bar (dynamic WEP, 30 seconds)
Temperature range: -40°C / +100°C.
Seal material: Water and oil-repellent PES membrane
Protection rating: IP66, IP69
Note: The pressure equalisation element will not function if it is blocked by dust and/or submerged in water.

Pressure equalisation elements with a particularly high air flow rate protect sensitive electronics. A temperature drop, for example due to changing weather conditions, can cause negative pressure to build up inside sealed enclosures. Water and dirt can then be drawn in through the seals, potentially damaging the electronics.
The pressure equalisation elements feature a metric connection thread. Suitable M12 lock nuts from the OKW portfolio are available for installation inside the enclosures.

Theoretical air flow rate RQ: 24 l/h - 0.07 bar
Water ingress point: > 0.2 bar (dynamic WEP, 30 seconds)
Temperature range: -40°C / +100°C.
Seal material: Water and oil-repellent PTFE membrane
Protection rating: IP66, IP69
Note: The pressure equalisation element will not function if it is blocked by dust and/or submerged in water.
