Kleinradialventilator SK1

VAKUTEC® - smal radial fan SK

 

Sizes and performance range

VAKUTEC small radial fan with the type designation SK7 and SK11 are single-suction, corrosion-resistant centrifugal fans. Two different sizes are manufactured:

  • The SK7 with an intake diameter of 75mm
  • The SK11 with an intake diameter of 110mm

Areas of application include small digestories, chemical cabinets, chemical containers, table suction systems, etc. This enables the controlled extraction of atmospheres up to a volume flow of 370m³/h and a total pressure increase of up to 450Pa.

The sound pressure level at a distance of 1 meter from the fan with connected suction and pressure lines is, depending on the motor manufacturer, motor type (AC and three-phase current / Ex motors) with connected suction and pressure sides:

  • for type SK7 ~52-58dB(A)
  • for type SK11 ~55-61dB(A)

Materials:

The impellers for both types are manufactured from PP using injection moulding. The same material and process is used for type SK7, while the housing of type SK11 is made of PVC, PPs or PE in welded construction.

 

Housing positions:

 

Due to the compact design, combined with very low weight

SK7 ~4.5 kg (with explosion-proof motor ~9.5 kg), SK11 ~5.5 kg (with explosion-proof motor ~10.5 kg), these centrifugal fans can be easily installed and mounted anywhere. For designs A, B and D, the fan can be installed according to local requirements. Type C is manufactured in position GL360 as standard. As a special design, all positions can of course be manufactured for the GL direction of rotation.

Impellers:

The impellers of the types listed above are manufactured from polypropylene (PPs) by injection moulding or in 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 motor flanged to the housing. The drive is an externally cooled 60W AC motor of type B5, protection class IP54, 220V, 50Hz, 2800rpm. However, the fans can also be supplied with three-phase and explosion-proof motors on request.

The fans in the SK series have ATEX certification for Zone CE Ex II 2(3) G T4.
