|
|
The NQ 250 - 400 is an outstanding range of wall-mounted air purification systems.
The patented technology of these products confirms their uniqueness. It constantly produces purified and sanitized air, with a uniform optimization of air flow and air volume within the entire room.
Consisting of 2 levels of mechanical filtration as well as an ultraviolet purification zone that destroys bacteria, viruses, fungi and molds. Units dimensions make these equipments ideal for several applications such as commercial, medical, industrial or military settings
Efficacy proven in real conditions for over 10 years (references available on request).
The ultraviolet disinfection allows our units to offer a high protection without utilising any chemicals or added materials.

The NQ 250-400 product range purifies air with 2 recognized processes:
FILTRATION - Two stages of mechanical filtration :
- 1 Pre-filter of 102 mm - 25-30% ASHRAE – G4
- HEPA filter ASHRAE- H13 (99.97% at 0.3 µm) - DOP
UV DISINFECTION - One germicidal UV lamp providing a total UV dosage of 12,447 to 19,334 µW sec/cm²

Working principle:
The top of the unit installed at 1.98 m above floor level creates a complete mixing pattern. The unit sends clean air to the upper part of the room, forcing heavier particles and droplet nuclei down away from breathing zone and into unit’s inlet.
Details:
- The air is recirculated into the bottom part of the machine
- Larger particles are trapped into the pre-filter (G4 - 25-30% ASHRAE)
- The air then passes through the UVGI (UV germicidal irradiation) chamber, a highly effective germicide, that destroys virus, bacteria, fungi and molds
- Finally 99.97% of particles and micro-organisms > 0.3 µm are filtered by the HEPA filter H13. This filter is constantly bathed by UV lamps. As the filter traps only micro-organisms that have been destroyed by UVC’s, there is no risk of replication in case of the unit is switched off
- Purified air is discharged, in the top part of the unit, via a discharge system specially designed (“Upflow”) to maximise and optimise the room effective air change rate |
