Axial air units

Air units VBPS-915

Description

  • Top performing air unit with 84.000 m3/h as highest flow rate.
  • Axial flow propeller with variable and adjustable pitch, 10 duraluminium blades.
  • Channel width adjustable from 195mm to 235mm.
  • Gear box with aluminium case and helicoidal gear teeth, 2 speeds + neutral point.
  • Clutch with 3 shoes of smooth and progressive starting and stopping.
  • Blower housing made of stainless steel with aerodynamic spokes of air input/output of 75mm.
  • Protective grids on suction and expulsion exits according to ISO-EN rules.
  • Reinforced frame made of galvanized steel (optional).

Advantages

  • The VBPS air units consist of two channels: A and C. The channel A is adjustable according to the needs of flow rate and air speed, which oscillates between 20m/s and 40m/s.
  • The low recoverer channel (called Turbo) transfers a 17,5% out of the total air to the most convenient clashing area. Moreover, they consist of a deflector of 10 variable pitch helicoidal blades, which generates a radial symmetrical air flow with turbulence preventing the leaves from compacting themselves.

Benefits for the Final Customer

  • Thanks to the higher level of air pressure we achieve the deepest penetration for wider crops’ frames.
  • Low power consumption
