Product description:

DWT roof fan product performance and technical parameters
Features: DWT roof fan by the impeller, hairdryers, hood, transmission parts, loose-leaf dampers, anti-bird nets, safety nets and other components. The fan duct, hood, impeller made of glass fiber reinforced plastic components can reduce the overall weight and a good resistance to corrosion, according to different requirements of air volume to applications, pressure and noise, use the following two forms of fan: (1) Axial roof fan; codenamed DWT-I type; wind volume; the more centrifugal pressure fan features low; (2) centrifugal roof fan, code-named DWT-II type, suitable for smaller air volume and pressure requires high.
use: DWT series Low noise roof fan is widely used in light industrial plants, senior civil supply and exhaust, especially for guitar and wet and corrosive gas emissions, medium temperature does not exceed 60 ℃, the gas must not contain excess viscous material, dust content less than 100mg / m3.
Specification: Axial roof fan specifications: DWT-I№3 ~ 24 total 17 kinds of specifications; centrifugal roof fan specifications: DWT-II№3 ~ 10 9 kinds of specifications.
