Andreae filter

An Andreae filter is used for efficient filtration by encapsulating liquid materials and fumes, such as paint, glue, oil and grease. Therefore, Andreae filters are especially suitable for use in for example paint booths. Often the filter is combined with a pre-filter media, for example a paint-stop media that captures the largest particles and thereby prolongs the lifetime of the Andreae filter.

Achieve effective filtration with your Andreae cardboard filter

An Andreae filter is based on the principle of inertia, which means that the particles are carried by the air flow and trapped in the V-shape of the filter, while the air continues unhindered through the upper holes in the filter. Since the air is not required to pass through the filter material itself, but instead through the holes, the static pressure is kept at a low level, whereby  the energy consumption is equivalently low. The filter also has 3-5 times longer lifetime than fiberglass, as there is no risk of the filter blocking as with a standard filtration.
