EDEA-SD Circular diffusers with fixed cones and integrate damper

Description

Circular diffusers with aluminium fixed cones complete with butterfly damper.

Characteristics

The diffuser is made of aluminium and painted white RAL 9016, while the butterfly damper is made of black plastic. It can be installed on false ceilings using the fixing bracket supplied with the diffuser. Should it be necessary to connect the diffuser to a flexible duct, there is no need to install the fixing bracket, but the EDEA-RF collar (sold separately) should be installed instead.

Use

The EDEA-SD circular diffuser with fixed cones is suitable for air conditioning, heating and ventilation applications, for both supply and exhaust. The installation height is normally between 2.5 m and 4.5 m. This type of diffuser is not suitable for environments with corrosive atmospheres, such as swimming pools, thermal facilities, and areas where chemical agents are used. In particular, chlorinated vapors and fumes are extremelyaggressive.

Accessories

EDEA-RFA – Galvanized steel collar for connection to flexible ducting.
