Fan Section

Centrifugal fan

• Forward blades
• Backward blades
• Wing profile backward blades
• Plug fan

They are built in a structure with alluminium double profile and put over high efficiency antivibrating mountings. The motor is always built over a beltpulling slide The pulley, under request, can be with variable step.
You have at disposal a wide range of accessories as safety micro-switch -that
switch off the fan when the door is open.

Plug Fans

• Directly coupled fan without cochlea
• The supply is free, for this reason all the fan section is under pressure and you can connect the supply duct where you need.
• Hi Efficiency
• An inverter is needed to modulate the power
• Self adaptive fan: you fix the air flow and the microprocessor modulate the rpm to compensate the change in the time of the pressure drops (due to dirty filters, wrong calculation of the duct....): works at constant air flow
