VAKUTEC® - Lightweight radial fan VL

 

Sizes and performance range:

VAKUTEC® - lightweight radial fans with the type designation VL are single inlet corrosion-resistant blowers. Five different sizes are manufactured:

  • VL-164 with an inlet diameter of 160mm
  • VL-184 with an inlet diameter of 180mm
  • VL-204 with an inlet diameter of 200mm
  • VL-254 with an inlet diameter of 250mm
  • VL-314 with an inlet diameter of 315mm

These centrifugal fans are used to extract exhaust air laden with chemicals, such as those found in chemical laboratories or electroplating. Controlled extraction of atmospheres up to a volume flow of 4,000 m³/h and a total pressure increase of up to 1,500 Pa is possible. The performance curves for the above-mentioned types are listed on the following pages.

The design of the fans with intake and discharge nozzles in the centre of the axis enables installation regardless of the direction of rotation of the impeller. The position of the fans can be adapted to the location by changing the mounting rails (loosening 4 screws). The possible positions can be found in the dimension sheet on the last page.

 

Materials:

The enclosures are manufactured using a CNC machining centre from polypropylene (PP), flame-retardant polypropylene (PPs), polyvinyl chloride (PVC) and polyethylene (PE) and assembled in a solid welded construction. In accordance with the UVV, the housings are surrounded by splinter protection. The standard equipment includes four swing elements, sleeves on the suction and discharge connections and condensate connections. The supporting structure is designed with mounting rails made of galvanised steel.

Impellers:

The impellers of the types listed above are manufactured from polypropylene (PPs) by injection moulding or in a welded design. If required, the impellers can also be supplied in steel with a corrosion-resistant coating. They are fitted with 6 backward-bent blades as standard.

Drives and motors:

The impeller is driven directly by a standard motor flanged to the housing.

The drive is a three-phase cage rotor of type B5 with protection class IP55.

The characteristic curves shown in bold in the performance curves are directly affected by the standard speeds 1.000 / 1.500 / 3.000 rpm directly.

The other characteristic curves are achieved by a frequency converter (230V/50Hz supply voltage) mounted on the housing. When using the frequency inverter, the power of the fan can be infinitely adjusted by the operator.
