Suction Band Filter

UBF – The Indestructible One

For applications with a high stock removal rate, and where fine filtration is required, nothing is more efficient than the Hoffmann Suction Band Filter System.

The UBF is extremely versatile, able to work with either oil or water-based coolants, and is excellent as either stand-alone or central filtration systems.

Fully automatic and easy to use, the Suction Band Filter pulls coolant through a filter media. This is done using the suction pump, which creates a low pressure area in a chamber below the media. When a specific vacuum is reached, the vacuum is released and the media transports automatically.

To set us apart from our competitors, the Hoffmann UBF – Suction Band Filter System uses a stainless steel wedge-wire screen to divide the dirty and suction chamber of the filter. To improve efficiency, our screen helps to prevent the filter paper from tearing, unlike standard perforated metal screens. The filter paper rests on the screen and the inclined discharge, where it serves as the primary filter and as support for the growing filter cake. By using a thicker filter paper and allowing a cake to build on it with the high stock removal, the UBF system is capable of achieving nominal filtration rates of 15 microns and below.
