The BDW4-87-11 explosion-proof and low-noise roof fan has been rationally designed for aerodynamic characteristics. With the aim of explosion-proof safety characteristics of the fan, proper structure and material selection and disposal have been carried out: the gap between the outlet of the wind collector and the inlet of the impeller is used. Adapt to increase the butt gap between impeller rotating diffuser and fixed diffuser; use FRP impeller; flame retardant added to glass steel parts such as casing and diffuser; YBDW type explosion-proof, low noise motor matching, rated voltage 380V , Motor explosion-proof rating: B3d is suitable for general-purpose explosion-proof ventilation equipment in the place containing flammable and explosive gas. In addition, due to the noise reduction measures adopted in the design and the selection of low-noise explosion-proof motors, the fan has low noise and is suitable for all environments where low noise is required.

The fan casing is made of glass steel, and users can choose different colors according to their needs and the color of the house building.

The gas passing through the fan should be non-corrosive and contain no significant particles of dust, and its medium temperature should not exceed 90°C.

The series includes No.3.55, No.5.6 two machine numbers, the performance of which refers to the selection table or characteristic curve.

1、Use and applicable conditions:

(1) use:

The fan is suitable for ventilation in various types of industrial and agricultural buildings, military buildings, workshops, laboratories, warehouses and other places where explosion-proof requirements are required.

(2) Ambient air conditions when used

Air temperature ≤90°C                                               

Relative humidity ≤85%

Dust content and other solid impurities content ≤ 150mg/m3

Environmental noise ≤60dB

2、Form:

The fan series consists of No3.55 and No5.6.

3、Performance and choice:

The fan performance generally refers to the performance of the fan under standard conditions, the performance of the technical documentation and the ordering requirements, and the standard shall prevail except for special orders.

The standard state means: atmospheric pressure Pa=101325 Pa, atmospheric temperature t=20° C., relative humidity Φ=50%, air density ρ=1.2 kg/m 3, and falling body acceleration g=9.8 m/s 2.
