Specification

The Singleflow SSD range of direct drive twin fans as manufactured by Elta Fans Ltd. 46 Third Avenue, Pensnett Trading Estate, Kingswinford, West Midlands, DY6 7US, UK. Tel: +44 (0) 1384 275800 - If you need more information - Contact us.

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 a suitably sized circular spigot to suit the duct size required. EPDM (Ethylene Propylene) rubber U shaped seals (being ozone and UV stable) are used to ensure a good seal back to the duct that is to be attached. Top & bottom access is provided as a standard feature to facilitate ease of maintenance and cleaning.

Motors

The single range of units may have either an EC or AC single rotor motor fitted as standard. The motor contains sealed for life bearings. Thermal Class of motors to THCL 130 or 155 dependent on size. Manufactured by Ziehl-Abegg providing increased reliability. All motors are suitable for use in ambient air conditions up to +60°C.

Impellers

High efficiency low tonal noise backward curved centrifugal impeller, dynamically balanced to Grade 6.3 and directly driven by the motor to provide a smooth airflow through the unit.

Quality Management

All units in the Elta range are designed and manufactured to procedures as defined in BS EN ISO 9001:2000. They are also tested in accordance with BS848 Part 2 1985 (sound performance) and ISO 5801:2007 (airside performance).
