ZerAx® Axial Flow Fans — Standard and ATEX

Product facts Product The Novenco® ZerAx® series of axial ow fans uses innovative design to reduce power consumption by improving efciency. As an extra benet, which depends on size and solution, the fans offer to improve the work environment by lowering sound levels. Application ZerAx fans are well-suited for both comfort and industrial ventilation. Versions for installation in ATEX zones in accordance with category 2G/D are also available. Range ZerAx fans for duct installation are designated AZN. Fans with free inlets or outlets are made by tting the fans with cones. The AZN fan casing is...

Description The ZerAx fans build on Novenco’s renowned Novax design. Almost every aspect of the fans is improved with this next generation fan. The materials and the use thereof have been rened. The design is made contemporary. And the efciency is improved, thus lowering overall power consumption and noise. All of this makes the ZerAx fans ready to comply with future environmental legislation. As with previous fan series, the ZerAx is suited for installation in diverse systems and environments. Built into comfort systems, such as residential housing ventilation and carpark ventilation, it...

Fan sizes mum efciency. At the same time the air quantities can of course be regulated, if needed. The fans are supplied with 50 or 60 Hz motors as standard, but can also be supplied with special motors. Speed control is either through direct start or through a frequency converter. The maximum speeds appear from the table below. Operational cost and space requirements are low for ZerAx fans, as fan sizes quite often are smaller than conventional fans with similar ows and pressures. The ZerAx fans present a serious alternative to centrifugal fans in ventilation and air conditioning systems...

Inside the ZerAx Minim Minimum blade clearance Pro Proled guide vanes of aluminium The rotor blades a milled with high precies are sion. The clearance be e between the rotor blades and the fan casing is kept to a minimum to pt optimise performance. Vanes are cast in aluminium and screwed on re to the motor mount and fan casing. or Unique blade efciency que ef The design of the blades brings the efciency iency above 90%. This is the highest level ever for axial ow fans. About the shown fan The fan shown here is the AZN 1000-350 for duct installation. It is tted with a short fan casing....

Durable fan casing The fan casing is of strong material and kept short to save weight. The design and material add rigidity and minimises critical vibrations. Frequency regulated motor (optional) Motors offered in connection with ZerAx fans can be frequency regulated with external converters. Extended fan casing (optional) High efciency motors Large motor sizes are accommodated through a long hub and extension of the fan casing. The long hub allows for position of the motor outside the motor mount. Motors in efciency classes 1 to 4 are available.

Types AZN for duct installation The AZN fans for duct installation can be tted with cones and thereby easily be turned into fans with free inlet or outlet. The casing is, depending on motor size, of AluZink or galvanised steel. With a thickness of 2 or 4 mm it is quite durable. The standard range comprise 9 installation sizes with Ø350 mm hubs and rotor diameters from Ø500 to Ø1250 and 7 installation sizes with Ø560 mm hubs and rotor diameters from Ø1000 to Ø2000. Air ow rates for AZN in the standard range run from 0.1 to 110 m3 /s and pressure increases up to 3400 Pa. The fan casing is...

Accessories Accessories for any purpose Anti-vibration mountings The ZerAx is offered with a wide choice of accessories presenting ample opportunities for customising fan solutions for virtually all installation conditions. These are cylindrical rubber discs tted on either the mounting feet or the vertical mounting plate. This prevents spreading of vibrations from the fan unit to the installation environment and vice versa. The thickness of the fan casing cannot be changed and varies depending on size and eld of application. The material is either 2 or 4 mm sheet steel. Acoustic diffuser...
