360-680mm Draught Foot-Path FRP Industrial Roof Ventilator and Other Ventilation Fans

1. Structure

        1). Material: made of stainless steel by stretching forming, attractive appearance, no rust.    

        2). Bearing:whole sealing bearing, which can ensure it operate smoothly and constantly.

•  

  3). Special central shaft design, high-class lubricating bearing system: preventing blades

   

  from deformation at high speed rotation, and extending the service life.   

   

  4). Inside support frame: cast aulumium. Light and anti rust.

• 2.Advantages 

   

  1 YEAR WARRANTY

   

  1). No Electrical Operating Costs, environmental protection, energy-saving.

   

  2). No Wiring Costs

   

  3). Desinged to withstand adverse weather

   

  3). Low maintenance, long life working.

   

  4). Low structural impact

   

  5). Quiet Operation

   

  6). Easy installation and position: suitable for flat and sloped roof

   

  7). waterproof efficiency reach 100%. 

   

  3.Function

   

  1). Exhausting turbid, humid hot air to exterior and supplying fresh air to interior.

   

  2). Produce air convection as a heat radiator, reducing indoor temperature, increasing air fresh.

   

  3). Reduce air conditioning load, increasing the cooling effect.

   

  4. Widely used in these places

   

  1). Ware house;

   

  2). Factories and workshops (such as paper mill, galvanized products producing factories,

   

  painting factories);

   

  3). Garage and other buildings which need air ventilation.
