Alpha Particulate Filter Range
Advancements in new technology, improved low differential pressure, and a step-change in performance ensures the Alpha Particulate Filters (dust filters) are the ideal solution for installation downstream of regenerative compressed air and gas dryers. Compressed Air Dust filters are designed for the removal of dry particulates. For example, they are perfect for installation downstream of regenerative air and gas dryers.
Walker Filtration’s Alpha Series Particulate Filters feature a redesigned housing and new element technology. Therefore, the flow-optimized design incorporates an all-new advanced filter head which is specifically developed to improve airflow and performance. Additionally, the Alpha series increases the energy efficiency within your compressed air system. Providing identical performance to our Alpha Coalescing filters, this comprehensive range of particulate filters deliver exceptional results in particle retention of up to 99.999%.
Furthermore, the Alpha Series of compressed air Dust filters are tested and validated to ISO 12500-3: 2009 guaranteeing the highest levels of air quality.
Up to 99.999% particle retention when tested in accordance with ISO 12500-3.

KEY FEATURES & BENEFITS
Walker Filtration’s particulate filters ensure exceptional results in particle retention of up to 99.999%, and significantly reduced pressure loss. Furthermore, the line offers total protection of manufacturing equipment from dust carryover.
Above all, due to significantly reduced differential pressure, the Alpha element delivers optimal performance and low operational lifetime costs in reverse flow applications, reducing the need for system maintenance.
Particulate Filter Models Available
The Alpha range offers 19 models with connection sizes from 1/8” to 3” NPT, Rp (BSP Parallel), and Rc (BSP Taper). Additionally, the series boasts a maximum operating temperature of 248˚F (120˚C), an improved maximum operating pressure of up to 300 psig (20.7 barg), and flow capacities up to 1500 SCFM (2550 Nm³/hr).
