Rectangular Duct Fan

   Rectangular Duct Fan

Standard Model: CRD

COSMOS CRD is a compact series of centrifugal type exhaust and supply in-line duct fans for air conditioning systems.

Product Description

COSMOS CRD is a compact series of centrifugal type exhaust and supply in-line duct fans for air conditioning systems.

They are specifically designed for installation where space is limited and allow installation directly at any angle and any location along the duct system.

Due to their silent operation, they can be used for direct air exhaust from the room or for air supply into the room.

Characteristics

●  Nominal connection dimensions from 300 x 150 mm to 900 x 550 mm
●  Air flow up to 12,000 m3/h.
●  Direct installation into air duct systems with housing connection flanges
●  Housing is entirely made of galvanized sheet steel
●  Motor with centrifugal backward curved impeller is mounted on a access panel, enabling easy servicing access
●  Backward curved high-efficiency impellers with external rotor motor.
●  Efficient, quality and user-friendly regulation.

Speed Control

Manual speed control of one or more voltage controllable 1 phase fans.

The desired speed is adjusted steplessly by the rotary button with switch function.

For a safe fan start up the setting begins with maximum output voltage. This can be reduced down to the internally adjustment for “n-min’.

Measurement of Characteristics

Performances tested at the world largest and most accurate lab in fan industry which is certified by TUV and AMCA according to DIN24163, EN ISO 3745.
