HMA Long Cased Axial Fans
Available in Standard, ATEX and Stainless Steel Construction
HMA 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 suitable for a wide range of medium pressure industrial applications and can provide airflows from 2220 m3 /h up to 144000 m3 /h.
To ensure an accurate fan selection, discuss your requirements or fan application with our team of experts. We’ll advise on the best solution with the aim to enhance efficiency and performance.
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.
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
