VAKUTEC® - Axialventilator SAX

 

General :

VAKUTEC high-performance axial fans with the type designation SAX are corrosion-resistant fans that are used to extract highly aggressive exhaust air. Areas of application include, for example, the extraction of acid baths, galvanic baths, laboratory or process exhaust air, etc. Naturally, the use of axial fans allows larger quantities to be transported compared to radial fans, but with a smaller overall pressure increase. In the most general application, the axial fan forms the fitting of a pipeline. By switching the fan into the pipe, the axial fan takes on the shape of the pipe externally without taking up any additional space. /

 

Materials :

Like the connected pipeline, the fan housings are designed according to the chemical and physical load. Possible materials are polyvinyl chloride, polyethylene, polypropylene, as well as polypropylene GRP and polyvinyl chloride GRP. The impellers of the SAX series are made of polypropylene using an injection molding process. There are 4 blade positions available (30°, 35°, 40°, 45°). /

 

Sizes and performance range:

The axial fans with the type designation SAX are available in 8 different sizes. The table below provides information about the designation, size, nominal speed and air volume range. However, the diagrams listed below serve to provide a more precise interpretation. Volume flow-pressure diagrams are available up to size 500 at nominal speeds of 1.500 and 3.000 rpm and for sizes 600 to 710 at nominal speed 1.500 rpm. However, by additionally installing frequency controllers, other speeds can also be achieved so that the suction power can be adapted to the actual requirements. /

 

Drives and motors:

The impeller is driven directly by a motor built into the fan hub. This design means that the motor is completely separated from the aggressive exhaust air. The drive is an externally cooled three-phase squirrel cage motor with protection class IP55. It is cooled by appropriately dimensioned servo fans. On request, the fans can also be supplied with explosion-proof three-phase motors. /
