Dz Series Ventilator from a sound source to start, low speed, high pressure coefficient design method, developed into a wide blade, big chord, space warp tilt leaf type, with a fan professional motor, with a significant low noise, air volume Large, low power consumption, small vibration, appearance, etc., is a highly efficient, energy-saving axial fans. Widely used in factories, warehouses, offices, homes and other places of the wall air exhaust pipe. Fans of the series are generally equipped with three-phase motors, according to user requirements can be equipped with the following 0.55kW single-phase motor. According to the requirements of the transmission medium can be made of corrosion, explosion-proof: FDZ as anti-corrosion axial fan, used to transport corrosive gas; BDZ be explosion-proof axial fans, for transporting flammable and explosive gases. FBDZ is corrosion proof type axial fans, for the transport of corrosive and flammable gases. DZ fans are after the original national standard based on the company's technology department developed from the noise point of view, set the low-speed motor, high winds high design pressure coefficient, widening impeller, plus grow chord, wide-angle, impeller twisted tilt leaf type, equipped with a fan motor, with a significant low noise, large air volume, low power consumption, small vibration, appearance, etc., is a highly efficient, energy-saving axial fans. Widely used in factories, warehouses, offices, homes and other places of the wall exhaust pipe blowing, but also according to different environmental changes the angle of the impeller, the different parameters required for each request. Fans of the series, there are three types :: DZ-11-type wall axial fan, DZ-12-type jobs axial fan, ZD-13 ducted axial fans. Special occasions, according to special user requirements can be designed with inlet and outlet grille, 45 degree elbow bend 60 degrees or 90 degrees from vertical louvers elbow, to prevent water intrusion, fans in the closure of the outside temperature effectively prevent and isolated, especially suitable for northern climates. DZ fans usually equipped with three-phase asynchronous motors, according to user requirements can be equipped with the following 0.55KW single-phase asynchronous motors. According to the different requirements of conveying gas medium made of corrosion-proof, explosion-proof: FDZ as anti-corrosion axial fan, used to transport corrosive gas; BDZ be explosion-proof axial fan, for transporting flammable gas. FBDZ is corrosion proof type axial fan, for the transport of corrosive and flammable gases. It can also be made according to the different requirements of customers to proof a higher standard, as BT4, CT4, various explosion-proof rating. Size fan diameter: Φ200 --- Φ1000mm air volume: 400 --- 50000m3 / h Pressure: 29 --- 343Pa
