BMAir F33

Due the merger of Freshfilter and BMAir, the F33 is now available. The F33 is Freshfilter’s heavy-duty system designed to handle the most severe contaminations.

900x440x295mm (LxWxH)
Air output:
nominally 40-120m³ per hour
Dust filtering:
possible with 2x dust filter (P1/P3)
24/12 Volts
  • Optimized protection
  • Full service
  • Sustainable solutions
  • Superior patented technology


This system protects operators during work in the dustiest environments combined with high gas and vapor concentrations. With its unique internal airflow, this stainless steel protective ventilation unit, the F33, is a true powerhouse and keeps operators safe in the most challenging conditions. Top-notch protection!

The F33 comes standard with P1 and P3 dust filters, and an optional 10 kg carbon filter can be installed. The F33 features gravity pre-filtration. The air is drawn in through the bottom of the P1 pre-filter. The significant advantage is that coarse dust particles can escape the F33 through vibrations, resulting in a considerable extension of the P1 dust filter’s lifespan. After the pre-filter, the air is drawn through the lid into the second filter compartment. The air is then blown through the subsequent filters (P3 and optional carbon filter) instead of being drawn in. This unique feature results in an extremely low airspeed and high air filtration. Optionally, the F33 has room for a 10 kg activated carbon filter.

The BMAir control system automatically regulates the pressure in the cabin and warns the operator of potential danger. Naturally, all systems and filters have been tested for their filtering effectiveness in an external laboratory. As a worldwide market leader and trendsetter in filter pressurization systems, we guarantee compliance with legal health and safety guidelines. However, compliance alone is not enough for us; we are happy to go the extra mile to ensure the safety and health of operators down to the smallest detail.

Our systems are delivered with controllers to be used in the cabins. This way, the machine operator has more protection during work activities in polluted environments. The system, being a protection device, warns the machine operator when caution is called for. You can choose between a standard model and a more customisable model with additional functions.
