Water Separators
Models | A3011WS to A3301WS
Flow Rates 6 SCFM (10 Nm³/hr) to 1500 SCFM (2550 Nm³/hr)

Integrating into Walker Filtration’s compressed air
filtration range, the New Alpha Water Separator
combines proven Alpha centrifugal technology
with a new forward thinking housing design todeliver market leading water removal efficiencies –
eliminating 99% bulk water with continuously low
differential pressure.
The custom engineered centrifugal module features unique vanes
to eliminate points of low efficiency, and a vortex arrestor to stop
re-entrainment - ensuring minimal operating pressure loss andmaintaining excellent liquid removal, even at low velocities.
No replacement components are required, making Walker Filtration’s
Water Separators a viable and cost effective solution for removing
bulk water from compressed air.

01.

Water Separators are fitted as standard with normally open float operated automatic drain valves, ADVS16 on models A3011 to A3051
and ADVSE16 on models A3052 to A3301. Standard filters operate at 16 barg (232 psig) at 80°C (176°F). Normally closed automaticdrain valves (ADVS16C) are available for low flow applications. 20.7 bar range (300 psi) at 120°C (248°F) available when supplied with amanual drain valve (MDV25 / MDVE25).

2.

Connecting kits are required to connect Water Separators to models A3011 to A3303 - see price guide.

3.

Wall mounting brackets are available for all models - see price guide.

4.

CThreaded connections are Rp (BSP Parallel) to ISO 7-1 or NPT to ANSI/ASME B1.20.1 if supplied within North America. Rc (BSP Taper)
Cto ISO 7-1 also available.

5.

For NPT threads, add the suffix N, e.g., A3052NWS, and for Rc threads add the suffix C, e.g. A3052CWS.
