Threaded Filters

Â
Walker Filtration offer a comprehensive range of compressed air and gas filtration products for use in almost every industrial environment. Within our new Alpha Series range of threaded filters we offer 19 models with connections from ¼" to 3" and flow capacities up to 1500 SCFM (2550 Nm³/h). Manufactured in cast aluminium alloy with Walker E-coat protection, the optimised modular filter design ensures that high performance, ease of installation and multiple close coupling is continually achieved.
Oleophobic borosilicate media and a custom engineered anti re-entrainment layer guarantees exceptional dirt holding and drainage. A unique material construction minimises pressure drop and improves energy efficiency, something that is crucial in todays economic climate. Our self centralising, drop-fit elements are colour coded to make grade identification quick and simple. A unique end cap design allows the elements to fully engage with the filter bowl to prevent vibration, improve stability and assist drainage.
Our Alpha Series range of threaded filters are independently tested and validated to ISO 12500 to give complete peace of mind.
