Breathing Air Filtration

The intelligent design of this two stage Duplex filter allows it to be installed in the same line space as a single stage filtration unit with twice the filtration capability. The Duplex filter is available in eight sizes with connections from ¼”to 1” (both BSPT and NPT compatible) and flows up to 297 Nm³/h (175 scfm).  Filters are manufactured in robust cast aluminium with an anti-corrosion Walker E-Coat™ to ensure durability.  The optimised design is space saving and modular allowing multiple close coupling.

Our unique elements have colour coded end caps making grade identification quick and simple.  Our unique end cap design engages with the bowl minimising vibration, increasing stability and assisting drainage.  Oleophobic borosilicate media and a custom engineered anti re-entrainment layer in the XA grade element guarantees exceptional dirt holding and drainage capabilities with minimal pressure drop.  The AC element uses a finely divided activated carbon media to remove odours and tastes.

Independently tested and validated to ISO 12500 standards.
