CENTRIFUGAL FANS

Centrifugal fans are for industrial installations, which require low or medium pressures. Facilities like composting plants and greenhouses are examples of industries that use centrifugal fans.
The design is robust, compact and suited to meet the requirements for long-life, service in corrosive environments and continuous operation.
The Novenco Centrifugal Fans are for universal installation. Versions for low and medium pressures are available with impeller sizes from Ø315 to Ø1250 mm, airflow rates from 0.2 to 21 m3/s and pressure increases up to 8500 Pa. Versions for low pressures are available with impeller sizes Ø250 to Ø1000, airflow rates from 0.2 to 18 m3/s and pressure increases up to 1500 Pa.
