Gray Aluminum Explosion Proof Duct Fan , Industrial Class 1 Div 1 Exhaust Fan

Technologies
The fan blades are turned by a brushless DC motor or an asynchronous AC motor. Unlike centrifugal fans, axial models do not operate at high pressure, but offer constant flow. These fans are mounted in an air duct, a wall or partition. A bell mouth and a diffuser enhance air flow and reduce noise. Output can be improved by using a turbine wheel at the upstream or downstream guide vanes. Some fans have two counter-rotating sets of blades, while others offer enhanced performance by changing the angle of attack of the blades.

How to choose
Choice will depend on nominal output flow, noise level, size, power consumption and voltage. Aeration fan selection is determined by the operating curves of the various models.

- Constant output

Disadvantages
- Low-pressure operation only
