Freshfilter F33 System

Dust particles can escape
The F33 incorporates gravity pre-filtration. The air is drawn in from the underside of the P1 pre-filter. The significant advantage is that coarse dust particles can escape through vibrations of the machine. This results in a substantial extension of the lifespan of the P1 pre-filter.

Extremely low air velocity
After passing through the pre-filter, the air is drawn through the lid into the second filter compartment. In this compartment, the air is evenly distributed before being blown through the P3 (and optional activated carbon) filter. This unique feature ensures an extremely low air velocity and 100% utilization of the filter surface area.

Variable combination height
Fill frames or complete filter packages are a thing of the past with the F33. Filters in the second filter compartment are tensioned using the included standard filter tensioners. The total filling height of the filter compartment is 150mm. However, any combination height of the Freshfilter filters can be tensioned.

Unique airflow
The Freshfilter F33 distinguishes itself from the rest with its unique airflow. Despite being equipped with a standard H13 dust filter, the filtration level of the F33 reaches even H14 level. This means that the F33 filters polluted air not only with 99.95% efficiency but with an even higher efficiency of 99.995%.

Fully automatic control
The F33 is equipped with automatic control. It is driven by the F4000 controller located inside the cabin. When the machine is started, the controller automatically activates. The pressure is promptly built up, ensuring immediate protection for the operator. If, for example, the positive pressure is insufficient, the controller will promptly issue a warning.
