HMA reinforced industrial axial fans with increased corrosion resistance can be

Optimised to Provide Specific Airflow Rates in Industrial Applications

The HMA range of long cased axial fans feature a reinforced steel fan casing with a polyester powder coat finish, offering enhanced mechanical strength, durability and high corrosive resistance. They are designed for wall or duct installation and suitable for air renewal in buildings and industries and smoke extraction with a maximum working temperature of 50ºC in single phase and up to 60ºC three phase.

Versatile Fans Suitable for Higher Volume Airflow

HMA long cased axial fans provide a comprehensive range of duties with the feature of variable pitch angle blades that are designed to provide a precise and efficient measure of high volume airflow in low to medium pressure systems.

Available Fan Types

HMA: Cast aluminium impeller with variable pitch angle

HM: Polypropylene impeller (A2 profile) or polyamide impeller reinforced with fibreglass (other profiles) with variable pitch angle

HMX: ATEX rated
