Walker Filtration researches, designs, and manufactures a comprehensive range of Ammonia and Refrigerant filters for use in specialist applications where the quality and cleanliness of the gas needs to be maintained to the highest level.

The range consists of eight stainless steel filter housings with connection sizes of ¼” to 2” with flow rates up to 675 scfm (1150 Nm³/h). This threaded range is precision engineered in high grade stainless steel.

These products are often installed within large industrial cooling systems and offer protection from the build-up of excessive amounts of oil on heat exchanger surfaces, prevent the blockage of tubes, valves, and expansion orifices, and also maintain the overall cleanliness and capacity of the system.

Our custom engineered filter media delivers exceptional filtration with minimum pressure drop. Threaded filters incorporate the unique Walker Filtration designed push-fit filter elements, which reduces maintenance time and allows the filter to be located within the most confined places.
