Flow Rates 6SCFM (10Nm3/hr) to 1500 SCFM(2550 Nm3/hr)
Integrating into Walker Filtration’s compressed air filtration range, the Alpha Water Separators combines proven Alpha centrifugal technology with a new forward thinking housing design to deliver 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 and maintaining excellent liquid removal, even at slow 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.

Technical Notes
- Water Separators are fitted as standard with normally open float operated automatic drain valves, ADVS16 on models A30006WS to A30050WS and ASVSE16 on models A#0070WS to A31500WS. Normally closed operated automatic drain valves (ADVS16C) are available for low range flow applications (2.5 SCFM, 4.2 Nm3/hr). 300 psig (20.7 barg) range at 248 °F (120 °C) is available when supplied with a manual drain valve (MDV25 on models A30006WS to A30050WS and MDVE25 on models A30070WS to A31500WS). Standard filters can operate at 232 psig (16 barg) at 176 °F (80 °C).
- Connecting kits are required to connect Water Separators to models A30006 to A31500
- Wall mounting brackets are available for all models
- Standard threaded connections are NPT to ANSI/ASME B1.20.1. RP (BSP Parallel) to ISP 7-1 and RC (BSP Taper) to ISO 7-1 are also available upon request.
