Description
- Speed-controllable
- Integral thermal contacts
- Can be installed in any position
- Maintenance-free and reliable
The RSI models have impellers with backward-curved blades and external rotor motors. The motor and impeller are mounted on the access cover to facilitate easy maintenance. The RSI models are thermally and acoustically insulated with 50 mm of mineral wool, with perforated sheet steel on the inner surface.
