Pressure filtration

for clear filtration of liquids which are difficult to filter

Pressure filtration was developed for the clear filtration of liquids which are difficult to filter using compressed air. A replaceable and sterilisable filter element with a filtration area of 65 cm² is designed for round filters with a diameter of 110 mm.

All filter materials can be used (paper filter, fibreglass filter, membrane filter, etc). Furthermore, filtration aids such as kieselguhr and activated charcoal can also be used. By contrast with vacuum filtration, pressure filtration is also suitable for easily volatile substances.

Central part of the filter unit is the replaceable filter element. This type of design permits easy cleaning and short filtration times. The filter element is sealed by a sturdy cover with valve and pressure gauge. An additional throttle valve allows the pressure increase in the filter element to be controlled.

It is closed with an easily operated eccentric. The filter unit is made of stainless steel and is designed for a working pressure of 6 bar. A removable polyethylene guides the filtrate into the sample beaker. A quiet compressor completes the system.
