Galvanised Centrifugal Fans
The highest corrosion resistance levels against
aggressive fluids or harsh environments. Entirely hot-dip galvanized casing and impeller.
A wide range of epoxy coatings with entire RAL color chart.
Certified customized coating processes up to C5M painting for the marine environment.
Ebonite protective coating through vulcanization of rubber, ceramic coating or halar coating
to resist corrosive agents as chlorine.
Steel surfaces can undergo pickling (decapage) or be treated with
eco-friendly micro-shot peening to enhance the quality of the product.
High Temperature Fans
High efficiency backward-curved impeller. Special hot-black coating
for high temperature fumes. Fans equipped with vibration sensors and cooling fan.
These fans may be supplied with
thermal or acustic coibentation systems. Cutting-edge insulation jacket to withstand high temperature fluids.
Thick carbon steel structure with
insulated panel. Suitable for industrial ovens. Structural resistance and reliability of the rotating component.
You can equip your fan with
drain cap, inspection door or protection nets, according to the requirements of your application.
We can provide you with
barycenter dimensional computation, specifying the correct models, quantity and positioning of the shock absorbers.
To prevent fluid leakages, we propose
labyrinth seals, packing seals, double-ring seals with grease chamber or flushed seals.
temperature sensors and speed sensors are important accessories to help you constantly check the fan during operation.
Availability of silencers and appropriate solutions to
reduce noise and limit dB sound pressure levels. Core ogive construction available too.
Inlet and outlet vibration-proof joints, also in wear-resistant version.
Throttle valves, opposed blade dampers and dapò flow regulators.
Customized impellers with
several blades configurations. Backward-curved, forward-curved blades, radial-shrouded, open and closed blades.
