Features and Benefits:

Easy Installation
All models are designed for direct connection to standard diameter flexible or rigid circular ducting with long spigots.

Easy Commissioning
Integrated commissioning control allows single speed selection and also limits 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.

Controllability
EC motors provide precise speed control via potentiometer, BMS or Elta Fans DCV control. Reduced fan speeds can provide significant cost-savings through lower energy consumption in both mechanical energy of motors and also on the conditioning of replacement air.

Warranty
Each SSDL has a 12 month warranty.

Specification:

Casing
Robust 1.2mm galvanised mild steel sheet casing. The casing is specially manufactured using integral motor mounting plates to provide additional rigidity for the casings. Each casing provides spigots to suit standard circular ducting.

Motor
EC external rotor motor fitted as standard. The IP44 motor contains sealed for life bearings. All motors are suitable for use in ambient air conditions up to +60°C.

Impeller
High efficiency low tonal noise backward curved centrifugal impeller, dynamically balanced to ISO1940-1 and directly driven by the motor to provide a smooth airflow through the unit.

Duct Connection Options
Can be supplied with rectangular outlet & inlet spigots on request.

Electrical Connection Options
Electrical cable entry from either side for ease of electrical connection as standard (a terminal box pre-fitted to either side can be ordered).
