Powered Industrial Exhaust Fans

Alpha Industrial Series Roof Exhaust Fans

Many industrial processes generate excess smoke, toxic gases and other kinds of fumes which are dangerous for the workplace.

This is why most industrial settings require a quality exhaust system to effectively and quickly remove these impurities and keep the air clean.

Roof exhaust fans are one of the best types of industrial exhaust and ventilation solutions.

The Alpha Industrial Series features a wide range of down-flow discharge axial fans which deliver excellent ventilation for warehouses, factories, retail locations, workshops and other industrial units.

All the fans in this series are able to handle a variety of ventilation and exhaust tasks

Flexibility in All Applications

The fans in the series come with adjustable impellers.

These impellers ensure that the air flow remains optimum while consuming the least amount of energy during operations.

For large industrial settings, this results in better energy conservation. You can also choose from nylon, aluminium or anti-static as the material of construction for the impeller blades.

The series features 6 exhaust fan sizes, ranging from 500mm to 1000mm in diameter.

All fans are perfect for smoke-spill applications and come with manual or automatic discharge damper fail-open latching
