The Iso-Mix-E fans combine the amazing versatility and outstanding performance of both axial and centrifugal fans.
These units are intended for combined supply and exhaust ventilation systems which are used to transport large amounts of air at high pressure while keeping noise under control.
The fans are compatible with air ducts from 355 to 450 mm in diameter. The units can be used for ventilation of residential, public and industrial spaces. 
The casing is made of steel with a polymer coating. Conical impellers with specially profiled blades help boost angular velocity of the air flow resulting in higher pressure and air capacity compared to the conventional designs. The fan casing is equipped with an external water-tight terminal box for electrical connections.
The fan motor shaft is mated to an impeller with diagonal blades. The units are equipped with single-speed 4-pole single-phase or threephase motors. The motors have thermal contacts built into the coils for overheating protection. Infinitely variable or stepped speed regulation is provided by means of athyristor or autotransformer controller. Several fans may share the same controller provided that the combined power output and operating current are within the controller ratings.
The fans can be installed at the inlet or outlet of the ductwork or in the middle. The ducts can be fitted at any angle relative to the fan axis. A single system may have several fans installed in parallel to boost the output capacity or in series to boost the working pressure.
