Features
- Supply and return air control for individual rooms such as offices, conference rooms and hotel rooms, in conjunction with a VAV box or a damper and flow probe.
- Pressure control in supply and return air ducts for low-noise, energy-efficient air distribution.
- Static measurement of differential pressure with MEMS sensor.
- Can be used for measuring in areas with dirty or contaminated return air.
- Low energy consumption and long serviceable life thanks to low-wear stepping motor.
- Electromechanical torque-based switch-off for safe operation.
- Extremely simple installation due to self-centring shaft adapter.
