Tagventilator RV

Description

A range of Vertical Discharge roof fans based on an integral axial impeller and internal rotor motor design. With specially designed bellmouth inlet and mounting plate, the roof fan is lightweight and ensures an excellent performance to sound level ratio, ideal for direct extract applications.

The cowl and roof mounting plate are moulded glass fibre reinforced polyester, which are high impact resistant and provide a rigid profile against strong winds. Resistant to UV light. Colour BS00A05. Alternative colours available on request.

A backdraught shutter kit is fitted as standard to all RV fans, ensuring full weather protection during shut down periods.

Suitable for flat or inclined roofs (max. angle 30°), designed for either kerb or purlin box mounting.

The RV range is available in nine models with extract performance ranging from 0.405m³/s up to 4.00m³/s (1,458m³/h to 14,400m³/h), with pressure characteristics of up to 150 Pa.

Motor/impellers

All sizes are supplied with cast aluminium impellers, ensuring performance when working against outdoor conditions and abrasive airflow.

Internal rotor motors are specifically designed and styled for this range of fan. Ball bearings are greased for life. Rotors are dynamically balanced to ISO 1940. Motors are protected to IP65 against dust and moisture complying with BS EN 60529. They have ribbed aluminium body castings for efficient cooling. Motor insulation is Class 'F' (from -40°C to + 70°C).
