Changing The Filter Element - Aventics NL1 Mode D'emploi

AVENTICS | NL1 / NL2 / NL3 / NL4 / NL6 | R412015556–BAL–001–AD | English

Changing the filter element:

System is operating under pressure!
Opening the system when it is under pressure can result in
personal injury and cause damage to the AS maintenance unit/
device.
O
Ensure that the system is pressure-free before opening the
reservoir.
Filters become contaminated with use and must be changed
punctually.
W
With differential pressure display NL: red marking shows
when a change is needed.
W
Without differential pressure display/differential pressure
gauge NL: for active carbon filters every six months, for all
other filters yearly. This, however, is only a recommendation,
since the interval depends on the quality of the compressed air
and the amount of air throughput.
