Air Filters for Commercial Vehicles

Robust, extremely light air filter systems made of recyclable plastic efficiently suppress intake noise and the transmission of noise through stucture born sounds.
Metal-free filter cartridges with efficient filter media and a high dust absorbtion guarantee up to 99.9 percent dust removal.
The applications involved in this case extend all the way to extreme operating conditions, for example in construction vehicles.

BOLL Duplex Filter

Duplex filters consist of two filter housings.
One half of the filter is in operation while the other is being cleaned or on stand-by.
If contamination exceeds a tolerance threshold, the unit can switch over to the clean filter side without any pulse pressure. The contaminated filter element is then cleaned while operation continues.
The change-over is performed by a change-over cock or by a two-stage three-way ball valve.
The design of the filter excludes simultaneous isolation of both filter chambers.
