Adsorption dryer type AQ-30B / AQ-31B / AQ-31L
- Stainless steel housing
- D-MAX rotary adsorber
- with air-cooled condenser, no moist air discharge required
- direct condensate drain (including pump)
- washable air filter
Product description
Efficient dehumidification without humid air removal
The AQ series from Kirsch-Tec offers high-performance adsorption dryers for professional use. Thanks to the AQUASORB operating principle, moisture is efficiently removed from the air – without any external humid air removal. This makes the appliances particularly suitable for closed rooms and applications where direct removal of the humid air is not possible.
Product advantages
✅ Stainless steel housing – robust, durable and corrosion-resistant
✅ D-MAX rotary adsorber – highly efficient moisture absorption, washable
✅ Air-cooled condenser – for energy-efficient regeneration
✅ Direct condensate drain – including condensate pump for reliable water drainage
✅ Maintenance-friendly design – easy access from the front and top
✅ Washable G4 air filter – quick cleaning without tools
✅ Flexible installation – for mobile or stationary use
Technical highlights
🔹 Dehumidification performance: 0.85 – 1.55 kg/h (at 20°C, 60% RH)
🔹 Air volume flow: 330 – 370 m³/h
