Ultra-compact centrifugal roof fans with horizontal discharge REA ≤5500 m³/h

• REA - ultra-compact and extra high performance, high pressure, centrifugal roof fans with horizontal discharge and self-cleaning impeller for extraction of higher polluted air and vapours from medium to large rooms
• REA are designed for easy installation, high efficiency and low noise levels

CONSTRUCTION

• base frame made of galvanised steel sheets
• protection by tensile steel wire, protected against weathering
• centrifugal impeller with rearward facing blades made of PA plastic, high efficiency and low noise
• aluminium upper casing protection

ENGINE

• bearing motors, protection class IP44 (models up to 254), other models IP54
• the fan designed to transport clean air at temperatures up to +40 °C

ACCESSORIES

• GR silencers with central cylinder. They reduce the noise produced by the fan. Sound-absorbing material: mineral wool. Frame made of galvanised steel sheet. Attention: to use the silencer in combination with the TS damper, silencers with a lowered central cylinder must be used

(see manufacturer's catalogue page for detailed dimensions and parameters)

• TS gravity dampers prevent heat loss through the roof when the fan is not running and the opening pressure is low. The dampers are opened by air pressure when the fan is running and close automatically when the fan is switched off. The structure is made of galvanised steel sheet. When used with the GR silencer, a version of the silencer with the capsule lowered must be used

(see manufacturer's catalogue page for detailed dimensions and parameters)

• CB metal base for fixing to concrete. With special fixing brackets. Solid construction for attachment to the fan pad

(see manufacturer's catalogue page for detailed dimensions and parameters)

• BA roof fan mounting pads for installation on corrugated surfaces

The BA support pad with transition RD is suitable for mounting roof fans on undulating surfaces, helping you to avoid damaging water stagnation near the fan and costly labour for installers. The BA support base is suitable for roof fans with a base size of 930 mm x 930 mm or larger. With the use of a suitable transition RD, the base can be used for roof fans with a minimum base dimension of 500 x 500 mm. The RD transition is a one-piece unit that can be easily cut to the exact dimensions of the fan.
