Roof fan with EC motor, with or without constant pressure

Application

These fans are designed for direct or ducted ventilation in residential, commercial and industrial buildings
Variable flow ventilation systems (eg can be combined with VAV valves) for optimum energy consumption (only for ARFV-S ECCP models)

Composition

Octogonal housing made of seawater resistant aluminium AlMg3
Turbine with backward-curved blades made of galvanized steel sheet up to type 280 and aluminum for all others, balanced G6.3 according to DIN ISO 1940
EC motor with internal electronic thermal protection
Flow regulation:

Constant speed control (0-10V control) for models ARFV-S EC 31
Constant pressure control for models ARFV-S ECCP 31

Voltage: 230Vac 1ph and 400Vac 3ph
Insulation class F (excluding ARFV-S 355 EC (CP) = B)
Protection class:

Motor: IP55 (excluding ARFV-S 190-250 EC (CP) = IP54, ARFV-S 280 EC (CP) = IP30)
Terminal box: IP44 (excluding ARFV-S 250 EC(CP) = IP54, ARFV-S 190 EC (CP) = none)
