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.
