Technical information
Additional information:
- Usually, 1 pressure compensation element per enclosure is sufficient, but this depends on environmental factors as well as on the sensitivity of the electronic devices present; we would therefore recommend that you carry out your own tests in any case.
- Chemical and solvent resistance of the membrane foil according to
DIN EN ISO 2812-1 (determination of the resistance against liquids,
test method 1 (dipping method)
Properties of the membrane foil:
- air flow rate: 0.4 l/min at 0.1 bar Delta P to 5.0 l/min at 1 bar Delta P
- water entry pressure: up to 1.0 bar
(this can be increased up to 1.5 bar. For this purpose, you are required to order an IP68-enclosure and the respective individual degree of protection test) - temperature stability: -40°C to +120°C
(as integrated part of an installation) - dust proofness acc. to EN 60529:2000
- water jet protection and protection against permanent immersion
EN 60529:2000 - protection against high pressure/steam jet cleaning acc. to DIN 40050

Air passage test:
The pressure compensation element was screwed in into a thread adapter and subjected to a defined quantity of air by means of a mass flow controller 5 LN/MIN and/or 20 LN/MIN made by Bronkhorst. In doing so, the air pressure was measured with a pressure sensor PMP 4070 from the same company shortly in front of the pressure compensation element.
The following amounts of air, as a function of the air pressure,
were determined:
Air pressure inside the enclosure | air passage |
0,1 bar | 0,8 l/min |
0,2 bar | 1,5 l/min |
0,3 bar | 2,2 l/min |
0,4 bar | 2,9 l/min |
0,5 bar | 3,7 l/min |
0,6 bar | 4,4 l/min |
0,7 bar | 5,2 l/min |
0,8 bar | 6,0 l/min |
0,9 bar | 6,8 l/min |
1,0 bar | 7,6 l/min |
