Range of single and double inlet direct driven low pressure centrifugal fans with external rotor motor. Available sizes from 133 to 200mm of impeller Ø. Scroll and impeller manufactured from galvanized sheet steel. External rotor motors with IP44 equipped with automatic reset thermal protector and ball bearings greased for life. All models incorporate capacitor fitted in the terminal box (single inlet models) or terminal block (double inlet models).

Low-Profile heat recovery units specially designed for false ceiling installation (indoors). Aluminium counter-flow heat exchanger up to 92% efficiency (EUROVENT certified), plug-fans with backward curved metal blades and EC motor.

Range of wall mounted in-line duct centrifugal fans, manufactured from high grade corrosion resistant pressed galvanised steel. All model include an enclosed type, single-phase external rotor motor with factory matched backward curved non-stalling impeller. All the impellers are manufactured from polyamide except model 315N which is made from galvanised sheet steel.

Range of in-line fans for circular ducts, designed for high aerodynamic performances with a very compact profiles and very low sound levels. Low profile compact casing manufactured from galvanised sheet steel. The terminal box and the mounting bracket do not increase the product’s profile. Optimised design of the impeller, guide vane and outlet diffuser, manufactured from injection-moulded plastic, to increase performance and lower the sound level. Airtight joint between the galvanised steel casing and the plastic guide vane to avoid air leaks. Rubber gaskets on the flanges to improve airtightness with the ducts. Silent-block between the motor and the holder to reduce the motor’s vibrations and lower the sound level of the installation, even in terms of speed regulation. IP65 terminal box allowing outdoor installation.

Heat recovery units with high-efficiency counterflow aluminium plate heat exchanger (up to 88%) certified by Eurovent, mounted in a galvanised steel double-walled enclosure with internal thermo-acoustic fireproof insulation (A1/M0) made of 25 mm thic

Range of low profile in-line mixed flow duct fans manufactured in tough reinforced plastic (from 160 to 2000 models) or with metal casing steel finished in a tough epoxy-polyester paint coating (for models 4000 and 6000). The unique design of the support bracket allows the motor and impeller assembly to be fitted or removed without dismantling the adjacent ducting.
