The nature of grinding applications means there are often larger swarf and dust particles that enter the extraction system. The pre-filter arrests these particles preventing them entering the Filtermist unit. This protects the internal workings of the unit, extends filter life, and reduces service intervals.
A Filtermist cyclone can be attached to the inlet of the Filtermist unit and the contaminated air will pass through it. The low-pressure area within the separator encourages the heavier particles to fall to its base where they can be easily removed.
