AUTO VISCOUS FILTER / OIL BATH FILTERS

HANDLAIR oil bath filter units have been developed for installing with ventilation plants, where the dust concentration in the surrounding air is comparatively heavier. It is very ideal for ventilation systems in coal mines, steel plants, cement plants, foundries and similar industries. These filters are available in different sizes, depending on the capacity.

This can be either direct or indirect driven. Each direct drive unit can be coupled with two indirect driven units, depending of the size.

In this filters, the dust is retained by adhesive action, when the dust laden air passes through the filter mat. The mat is cleaned and re oiled as it passes intermittently through the oil bath. Drops of oil that may be carried through are trapped by the oil drop eliminator.
