Pressure compensation element for M 20 knockouts
For the reduction of condensation by pressure compensation in power distribution systems
ISO thread M 20 x 1.5
Bore-hole: Ø 20.3 mm
Wall thickness up to 4 mm
With counter nut
For indoor (normal environment and/or protected outdoor) and outdoor installation (harsh environment and/or outdoor)
Ambient temperature – 25 °C to + 55 °C
In order not to exceed leakage limit of 0.07 bar with pressure compensation, one pressure compensation element BM 20G must be used per 28 litres (28000 cm³) of enclosure volume.
Example: enclosure size 30 cm x 60 cm x 17 cm = 30600 cm³ = 30,6 litres. Number of necessary BM 20G (M20) = 2 piece.
