Features and Benefits
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.
Integrated commissioning control allowing single speed selection and also limiting maximum speed if used with an external potentiometer.
Ideal for very shallow ceiling voids or where space is at a premium.
Low power consumption at high performance resulting in Low Specific Fan Powers for Building Regulation Compliance.
EC motors providing precise speed control via potentiometer, 0-10VDC or PWM Circuit. A potentiometer controller is available for manual control. Reduced fan speed can provide significant cost-savings through lower energy consumption in both mechanical energy of motors and also on the conditioning of replacement air.
Each SH has a 12 month warranty.
A robust 1.2mm galvanised mild steel sheet casing. Each casing provides spigots to suit standard circular ducting. A removable lid is provided as standard to allow easy maintenance and cleaning.
A brushless EC motor is fitted as standard. The IPX4 motor contains sealed for life bearings. All motors are suitable for use in ambient air conditions up to +60°C.
High efficiency jet design double mixed flow impeller, directly driven by the motor to provide a smooth airflow through the unit.
