FAS‑ASD‑WS Water Separator for condensing water vapor
and collecting condensate from the pipe system
The FAS‑ASD‑WS Water Separator can be operated in a temperature range from 0 °C to
+50 °C. The sintered metal filter in the water separator has a pore width of 50 µm and causes
an additional rough absorption of soil particles.The FAS-ASD-WS is supplied with an angle
support and PG cable glands. The 45° pipe elbows (4 units) must be ordered separately.

Detonation safety barrier for potentially explosive areas

FAS / FCS
Detonation safety barrier in the aspiration pipe system and if
necessary in the air-return pipe
Vapor/air and/or gas/air mixture ignition in the aspirating smoke detector may result in pipe
explosion or detonation. This depends on the composition, concentration, temperature, and
pressure of the flammable mixture.
The detonation safety barrier is a flame trap that is flame-proof in the face of pipe explosions
(deflagrations) and detonations.
