4-72 / 6-30 Centrifugal Fans
Air supply for mill aspiration and pneumatic conveying. Choose a fan by airflow and total pressure at the working point, together with drive speed and motor power.

Ranges describe the operating envelope; maximum flow and maximum pressure are not a simultaneous duty point. Standard 4-72 clean-air duty: dust and hard particles ≤150 mg/m³, gas temperature ≤80°C.
On small screens, scroll the table to see all specifications.
Choose for the operating duty
Match airflow and pressure at the same operating point. Send the duct layout, equipment resistance and air temperature; a motor rating alone is not a fan selection.
- 4-72 configurations for clean-air ventilation and compatible extraction duties.
- 6-30 configurations for higher-resistance process-air and pneumatic conveying duties.
- Define whether product travels through the fan or is separated upstream.
Plan the installation
Air duty
Provide airflow, operating pressure and the conveying or extraction layout.
Connections
Show inlet and outlet sizes, direction, flange arrangement and available service space.
Material
Describe dust loading, particle size, moisture and the material being handled.
Installation
State voltage, frequency, operating temperature and any site-specific protection requirements.
Existing equipment and spare parts
For a replacement, send the nameplate, a photograph, connection dimensions and the required duty. For individual parts, include dimensions and the machine serial number.
