Summary
See more specification See less specification
The Systemair DHS Sileo 225EZ is a 225mm centrifugal roof-mounted extract fan delivering up to 850 m³/h. Its 3D profiled backward-curved impeller and external rotor motor give high airflow at medium pressure with very low noise, making it well suited to exhaust ventilation on single and multiple dwellings, offices and light commercial buildings.
The 225EZ runs on a single-phase 230V AC motor (EZ, 2-pole 2-speed) with horizontal discharge and is fully speed controllable over the voltage. An integral thermal contact with manual reset protects the motor, the aluminium casing suits coastal applications, and it handles air up to 60°C at IP44.
