Features:

• Wall fixing panel made of phosphated steel sheet, painted with grey polyester powder paint with hammered effect to guarantee resistance over time to atmospheric agents.
• Single-bodied mouthpiece with panel, calibrated to optimize airflow
• Protection grille (conforming to UNI ISO 13857) integrating the motor support function, made of electrowelded steel rings and painted with black epoxy paint. Easy removal simplifies maintenance and cleaning of the fan.
• Three-phase asynchronous AC motor with 1 speed, with shaft mounted on ball bearing supports with double sealing shield, with electrical insulation class F
• Maximum flow rate 1,000 m3/h
• 6-blade impeller with wing profile splined on a die-cast aluminium hub, dynamically balanced (UNI ISO 1940,- Balancing Class 6.3), optimized to maximize performance and sound levels, moulded in charged polypropylene to achieve high levels of dimensional stability and resistance to atmospheric agents.
• Speed controllable by Vortex regulator.
