Alpha Filters

Compressed Air Alpha Filters

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.

Correction Factors

For maximum flow rate, multiply model flow rate by the correction factor corresponding to the minimum operating pressure:
Inlet Flow Rate x Operating Pressure CF = Maximum Flow Rate
