HM Long Cased Axial Fans
Available in Standard, ATEX and Stainless Steel Construction
Manufacturing Features:
Long cased axial fan with motor-impeller modular assembly for complete versatility.
Reinforced casing manufactured from rolled sheet steel and finished with a polyester powder coating.
Polypropylene impeller (A2 profile) or polyamide impeller reinforced with fibreglass (other profiles) with variable pitch angle.
Standard asynchronous squirrel-cage motor with IP55 protection and Class F insulation.
Manufactured with standard voltages: 230V 50Hz in 1~ motors, 230/400V 50Hz in 3~ motors up to 4kW and 400/690V 50Hz for higher powers.
Maximum operating temperature: 50ºC in 1~, 60ºC in 3~.
Variable Pitched Angled Blades for Higher Volume Airflow Rates
HM Long cased axial fans feature optimally positioned variable pitch blades to provide high volume airflow rates at precise and controlled measures to maintain the highest efficiency during performance.
HM: Polypropylene impeller (A2 profile) or polyamide impeller reinforced with fibreglass (other profiles) with variable pitch angle
HMA: Cast aluminium impeller with variable pitch angle
HMX: Cast aluminium impeller, ATEX rated
Designed for inline installation, they are suitable for:
• Air renewal in buildings and industries
• Smoke extraction (max 50-60ºC)
• Maximum working temperature: 1ph 50ºC, 3ph 60ºC
Contact us for the following options:
• 100% reversible impeller
• 60Hz fans and special voltages
• Hot-dipped galvanised or stainless steel housing
Airflow is dependent on the model and the application set up but the HM range offers airflows up to 151010m3/h. Contact us for a more accurate duty for your application.
Technical Data
