Acoustically lined single inline centrifugal fans with demand control. Designed to monitor and control one or more fan units simultaneously, with 6 pre-programmed fan applications. Supplied Multi-function remote control panel with LCD display.

Low Noise
Each unit is acoustically lined internally with Class O rated (BS 476 Parts 6 and 7) fire resistant acoustic foam lining minimising breakout noise levels.

Easy Installation
New multi-mount brackets allow easy mounting in a range of orientations.

Easy Commissioning
Integrated commissioning control allowing single speed selection and also limiting maximum speed if used with an external potentiometer.

Efficient Performance
High efficiency low tonal noise backward curved centrifugal impellers are directly driven by an EC external rotor motor, provide low specific fan powers and stepless speed control without tonal noise generation..

Weather Resistance
Units can be weatherproofed in the factory to allow external installation.
