Water vapour occurs naturally in air and is present in the hot air discharged from air compressors. The hot air will then release condensate as it meets the colder surfaces of downstream equipment.
Although the condensate can be removed via drains, liquid will remain in the air stream. This liquid condensate will break down lubricating oils, increasing friction between moving surfaces and corrode exposed metal components.
For compressed air installations where water contamination is a real problem, Walker Filtration's range of silicone free water separators can deal simply and effectively with the problem.
Typically, water separators are installed downstream of after coolers and air receivers, refrigerant dryers and at strategic points in pipe work installations.
The design utilises an internal spinner which removes large quantities of condensate by centrifugal action. Water separators are available for operating pressures up to 16 barg (232 psig).
