Price includes 8.1% VAT.
Industrial air purifiers – professional protection against dust, spores & pollutants
The Aktobis industrial air purifier is the highly effective solution for environments with extreme air pollution. Whether on construction sites, in production halls, or during renovations – the device reliably protects employees from harmful particles. Furthermore, targeted air purification effectively prevents the contamination of adjacent rooms (dust barrier principle).
Highly efficient 3-stage filter system
- Coarse dust filter (G4): Captures particles > 10 µm with an efficiency of over 90% and protects the subsequent fine filters.
- HEPA filter (H13): The medical standard. Filters 99.95% of all particles down to a size of 0.0003 mm (fine dust, bacteria, mold spores).
- Activated carbon filter (included): Neutralizes odors, smoke, toxic fumes and solvent gases.
Features & Benefits
- Extremely robust: The housing made of special plastic is impact-resistant, durable and particularly easy to clean.
- Stepless control: The air output can be precisely adjusted to the room size and dust load using the rotary control.
- Smart Restart: In case of a power interruption, the device automatically restarts with the last selected setting (ideal for timers).
- Mobility & Design: Compact design with integrated carrying handle and an extra-long power cord (7.3 m).
- Stackable: For maximum space saving in the warehouse or for combined performance increase in the operation.
