Novax are compact, robust, series-produced axial flow fans with presettable blades. Novax fans are installed in a wide range of ventilation systems on shore and off-shore: Comfort systems, in- dustrial, process, parking and tunnel ventilation as well as environment-enhancement systems. The fans require little space, are easy to install and offer high operational reliability. The Novax rotor consists of a pressed, two-part, as- sembled hub with depressions in which the blades are fixed. The rotor is provided with a hub boss on one side for mounting on a motor. The rotor blades can be fixed...

The fans are supplied with 50 Hz motors as standard, but can also be supplied with 60 Hz motors. Alterna- tively, they can also be speed controlled by means of frequency inversion with the maximum speeds indi- cated in the table below. Nominal RPMs for 50 Hz motors are found in the per- formance curves on pages 10 through 15. Thus Novax fans are a serious alternative to centrifu- gal fans in ventilation and air conditioning systems with varying air flow rate requirements. Using frequency inverters removes the limitations Thus axial fans can virtually always be placed within the maximum...

The diagrams indicate the coverage for each of the fan sizes without taking the hub diameter into consider- The capacities are based on fan installation in accord- ance with BS 848 1980, installation type D (duct con- nection for inlet and outlet). Other installation types yield other data. The air density is p = 1.20 kg/m . Final dimensioning, including calculation of blade angles, choice of motor, power consumption plus sound calculation, is done on Novenco's web site.
