ROOF FAN

1.Summary
Various models, large application scope: 2 models are available according to different pressures, air flow and noise requirement:
a. Axial roof fans: model DWT-Ⅰis for medium and low pressure, large volume condition. Its design can be changed into dual-reversible type with the same efficiency (national patent).
b. Centrifugal roof fan: two models: DWT-Ⅱ. It is applied to provide high pressure while low air volume.
2.Features
High-efficiency, low-noise: This series uses CAD software, after optimizing design and research, its design has been rewarded patent of utility model and national outstanding patent. Its design adopts different rotate speeds, angles and impellers with the same diameter to satisfy different conditions. In this way, the fans match with the whole system and save energy and bring down noise.
Stable operation, long-term service: little inertia, precise balance, stable operation make the fan's performance standard higher than its competitors.
Large applying scope: This series fans can be made into explosion-proof, retardant, anti-aging type, etc., for ventilation of the conditions of flammable, explosive and corrosive air.
