Walker 105 SCFM 1" Oil Vapor Removal Filter · 0.003 ppm · 0.01 micron
The Walker A30105 comes equipped with a manual drain valve and a 1" pipe size inlet with a flow rate of 105 SCFM. With the included E30612 Grade XA filter, this unit removes 0.01 micron particles with a maximum oil carryover of 0.003 ppm. Complies with ISO 8573-1: 2010 (maximum particle size class and maximum oil content).
Introducing the Alpha, Walker Filtration’s latest range of market leading compressed air and gas filters. With enhanced housing features and a step change in element performance, the Alpha delivers a high quality filtration solution you can trust.
Offered in a range of 18 models with connection sizes ranging from 1/8” to 3”, the Alpha Series has been tested to provide a saturated differential pressure of <1.8 psi (125 mbar) across X1 and XA grades—proving to be our most advanced filter to date.
With class leading performance and exceptional results in oil aerosol and particle retention, Alpha Compressed Air Filters deliver significantly reduced pressure loss and optimum filtration efficiencies—to ensure continually low operational costs.

Technical Notes
- Direction of air flow is inside to out through the filter element.
- Pop up indicators (65DPUG3) are fitted to models A30025 to A30050 as standard. Differential pressure indicators (65DPIG) are fitted to models A30070 to A31500 as standard. Activated Carbon (AC) grade filters do not include DP equipment. Volt free contact options are available upon request - see price guide.
- Coalescing Filters are fitted as standard with normally open float operated automatic drain valves, ADVS16 on models A30006 to A30050 and ADVSE16 on models A30070 to A31500, and manual drain valves on Activated Carbon Filters. Standard filters can operate at 232 psig (16 barg ) at 176°F (80°C). Normally closed operated automatic drain valves (ADVS16C) are available for low range flow applications (2.5 SCFM, 4.2 Nm³/hr or lower). 300 psi (20.7 bar) range at 248°F (120°C) available when supplied with a manual drain valve (MDV25 on models A30006 to A30050 and MDVE25 on models A30070 to A31500).
- Activated Carbon Filters must not operate in oil saturated conditions and will not remove certain types of gases including carbon monoxide (CO) and carbon dioxide (CO2).
- Alpha Filters are manufactured from cast aluminum alloy and are PED 2014/68/EU compliant for group 2 gases.
- Standard threaded connections are NPT to ANSI/ASME B1.20.1. RP (BSP Parallel) to ISO 7-1 and RC (BSP Taper) to ISO 7-1 are also available upon request.
- Filters are suitable for use with mineral and synthetic oils plus, oil-free compressed air applications.
