Walker Filtration Introduces Revolutionary Multi-Banked Solution to Compressed Air Filtration

PUBLISHED Tuesday, May 9 2017

Walker Filtration has used their technical expertise to once again create an innovative new filter range. The PRO XF is a high efficiency, compressed air filter, featuring an innovative modular design to provide a flexible, reliable and compact compressed air filtration solution. To support the product launch Walker Filtration has also launched an online product space:, dedicated to the business’ new, market-leading product launches.

Designed for high flow applications and operating pressures of up to 16 barg, PRO XF has revolutionised the fabricated flanged market – providing a reliable and flexible modular design that is ideal for use in multi compressor installations and skid based packages.

By expanding the range to include threaded variants, PRO XF delivers a comprehensive product range with flow rates from 700 to 3000 scfm (1189 to 5097 Nm³/hr). Available in 2”, 2 ½”, 3” BSPP and NPT threaded, and DN80 (3”) and DN100 (4”) flanged housings, the PRO XF range is suitable for installation worldwide.

Through innovative design and lean manufacturing, Walker Filtration has been able to significantly reduce lead time when compared to conventional fabricated vessels, holding all components in stock.

PRO XF’s unique modular construction is available as individual threaded or flanged ‘Complete Filters’ which, by integrating with PRO XF ‘Filter Modules’, can be multi-banked to create a space efficient filtration solution. The PRO XF design is up to 65% lighter and 45% smaller when compared to comparative fabricated models. With a 30% cost saving on each Filter Module, when multi-banking with an equivalent sized complete filter, this revolutionary design not only saves on space and service time, but money too.

Featuring five filtration grades, from 25 micron to 0.01 micron, for particulate, vapour and coalescing filters – PRO XF filter elements are manufactured using quality materials to provide optimal performance, minimal pressure drop and reduced whole life costs. The new PRO XF range will meet and exceed the highest standards of air purity when tested in accordance with ISO 8573-1:2010 air quality classes to provide a safe and reliable compressed air filtration solution.  

The range also includes Water Separators, removing 99% of bulk liquid in line with ISO standard 8573-9. The centrifugal module has been custom designed to feature a Vortex Arrestor to stop re-entrainment and eliminate points of low efficiency. This ensures minimal operating pressure loss and maintains excellent liquid removal, even at low velocities. No replacement components are required for the PRO XF Water Separator, making it a viable, cost effective solution to removing bulk water from compressed air.

PRO XF delivers significant reduction in maintenance and installation time, with savings of up to 80% for the flanged product when compared with traditional filter vessels. PRO XF incorporates a unique top loading screw cap design, and a new ‘Easy Grip’ filter element, to provide improved accessibility to the filter element and quick and clean element change-out. Combined with a new externally accessible drain which eliminates the need to gain access to the internal of the filter bowl to remove the drain - servicing has never been easier.

Lianne Walker, MBE (MBA) Group Managing Director said “We are very excited to bring a revolutionary change to the design of our air filter range. By incorporating engineering excellence and innovative design, Walker Filtration have delivered a world-class, modular design that is easy to install and most importantly is available in stock.  PRO XF provides improved operating efficiencies by reducing service time and improving ease of installation, which is why our clients and customers have put their trust in our product for over 30 years.”
