The Freshfilter F33R is a universal pressure relief filter system for trucks and roof-mounted (compact) excavators. The system is mostly used on trucks, which can be mounted in the roof hatch with a brand specific adapter.
The F33R system uses filters with the dimensions 600x336mm. In the filter compartment an activated carbon filter of 10 kg can be placed in combination with a P1 and P3 dust filter. This makes the F33R extremely suitable for the toughest decontamination classes.
The UV-resistant ABS hood on the F33R can be easily opened thanks to the tilting system. When changing the filters, the hood does not have to be removed. This leaves the mechanic's hands free to change the filters safely on the roof of the vehicle/machine.
Order only the filters that are needed through Freshfilter's new quick-fit system. The total filling height of the filter compartment is 150mm. However, any combination height of the Freshfilter filters can be clamped. Filling frames or complete filter packages belong to the past with the F33R.
