Air-In® supply air valves and noise reducers offer superior noise reduction values and the draught-free air quantities.
AIR-IN® NOISE REDUCERS
The Air-In® noise reducer effectively reduces noise from machines and ducts as well as noise between flats. It allows a maximum inflow of air of 250 litres per second with efficient noise reduction.
The Air-In® noise trap achieves better results using a single damper than most other products using two.
Features
- Superior noise reduction
- Damper for adjusting the amount of air
- Measurement connections for measuring the amount of air
- Acts as a cleaning hatch of the ducts
- Thanks to its compact size, it is easy to install in narrow spaces within false ceilings
- Manufactured from durable galvanised steel
- Does not contain wool, meaning no loose particles are released into the flow of air
- The product is light and no separate support structures are needed

AIR-IN® 125 SUPER SILENCER
The Air-In® 125 Super is a new generation silencer designed according to the increased requirements of house noise reduction.
Air-In® 125 Super is better than its predecessor in almost all octave bands. The amount of air can be adjusted steplessly and without noise. The silencer is therefore very well suited for use as a damper/attenuator when lots of branches are taken from the main air duct. The silencer also includes measurement connections for the measurement of the amount of air as well as a large cleaning hatch for cleaning the ducts. Compact size is one of the important features of Air-In 125 Super.
Features
- Very small size, only 250 mm x 450 mm, height 200 mm
- High damper capacity in the important octave bands
- Stepless adjustment
- Measurement connections for measuring the amount of air
- Acts as a cleaning hatch
Application
- flat buildings, terraced houses, detached houses
- schools and office buildings
