Singleflow SSDL fans are suitable for external mounting. The range incorporates advanced backward curved impellers.

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

Integrated commissioning control allows single speed selection and also limits maximum speed if used with an external potentiometer.

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.

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.

Each SSDL has a 12 month warranty.
