Compare NEX AirGuard AG301 with other NEX AirGuard models.
The NEX AirGuard AG301 employs advanced MicroPlasma BiPolar Ionization technology to tackle challenging air quality issues in industrial settings. Its specialized Odors Elimination System is particularly effective in areas with poor ventilation, targeting:
- Sewage and wastewater treatment odors
- Chemical fumes
- Bacterial decomposition odors
- Damp and musty smells
- Industrial process odors
The system’s hydroxyl ion generation technology specifically targets hydrogen sulfide (H2S), a common cause of sewage odors and infrastructure corrosion. Through the chemical reaction: H2S + OH- = HS- + H2O
The AG301 converts harmful hydrogen sulfide into harmless sulfur and water molecules, effectively eliminating both the odor and associated health risks. This makes it ideal for:
- Wastewater treatment facilities
- Building parking structures
- Locomotive maintenance facilities
- Commercial kitchens
- Slaughterhouses
- Veterinary clinics
- Hospitals and medical facilities
