Fabricated from carbon steel, these filter housings offer flow rate capacities up to 425m3/min. Twelve models in the standard range offer 25mm-300mm flange connections. The inclusion of features such as outlet pressure gauges and differential pressure indicators allow continuous monitoring of filter performance and indicate the optimum point at which the filter element should be replaced. The coalescer grade filter elements use high efficiency borosilicate glass micro-fibre media to remove dirt particles and to coalesce oil mists. They are available in a range of 25, 5, 1 and 0.01 micron filtration grades to encompass all requirements. Low air velocities prevent oil carry-over to ensure guaranteed performance. The range also includes grade AC (activated carbon) elements for removal of certain hydrocarbon vapours and odours as required for high specification applications.
