MB • Centrifugal fans

Single inlet centrifugal fan

Application

  • MB blowers are used for applications where slightly dusty air has to be removed.
  • The fan is suitable for handling air up to 80°C.
  • A protection hood is required for outside use.

Composition

  • The casing is made of spot welded sheet steel and painted in epoxy RAL 7031 with a total thickness of 80µ. The strong base frame support the motor
  • The impeller with forward curved blades is dynamically and statically balanced grade G6.3 according to ISO 1940/1. The many concave blades (30 or more) gives a great air volume at low speed which is benefit to a low noise level.
  • Totally closed squirrel-cage asynchronous motor
  • Protection IP55 – Insulation F
  • Supply: 230Vac 1ph 50Hz (Steinmetz type) - 230/400Vac 3ph 50Hz and 400/690Vac from 5.5kW motors

Accessories

  • Inlet flange, type RNFLA
  • Outlet guard, type RDP
  • Square/round piece on outlet, type RC
  • 5-steps transformer speed controller 230V, type TSCTK-1
  • 5-steps transformer speed controller 3x400v, type TSCTK-4
  • Frequency converter 1x230V, type FIS(-C)-11-B
  • Frequency converter 3x400V, type FIS(-C)-44-B

Options

  • ATEX II 2G T3 version
  • High temperature 180°C version
  • 2-speed motors
  • Stainless steel version
  • Belt driven version
