Drum filters: 360° molecular filtration for cleaner air
Molecular drum filters with activated carbon are a highly effective solution for odour control and the adsorption of acidic gases and toxic chemicals in exhaust air filtration applications. Their simple yet robust design allows for easy installation and operation, even in the most demanding environments.
MANN+HUMMEL drum filters deliver extended contact times, effectively removing even high concentrations of airborne molecular contaminants (AMC) and strong odours from the air. Our housings, made from high-density polyethylene (HDPE), are extremely durable, versatile, and adaptable, making them a reliable choice across a wide range of sectors and industries.
The main advantages of our drum filters at a glance:
- Reliable protection against AMC, toxic chemicals, corrosive gases, and unpleasant odours thanks to specialised activated carbon filter media
- Simple maintenance and operation for optimised performance
- Extended contact times for dependable filtration
- Long-lasting construction design thanks to durable HDPE
- Various sizes and media to suit individual requirements
