The F33R has a very limited height!

The F33R is a universal cabin air filtration system for lorries and compact excavators. The system be mounted on the roof of a machine or vehicle.

The F33R system uses filters with dimensions of 600 x 336 and has a filling height of 150 mm. A 10 kg activated carbon filter, P1 in combination with a P3(H13) dust filter can be positioned in the filter compartment, making it suitable for the toughest decontamination categories.

The UV-resistant ABS hood on the F33R is easy to open, thanks to the tilting system. There is no need to remove the hood when replacing filters. This leaves the fitter’s hands free to replace the filters easily on the roof of the vehicle/machine.

The basis of the F33R overpressure filter system is produced by RVS in our own factory. By manufacturing our own product, we guarantee the use of only the highest quality materials. The F33R is fitted with quick-release locks, so that the system can be opened easily, without the need for tools.
