Air supply system
V2000 AS

V2000 AS air supply system

The hydraulically driven V2000 AS compressor is used on tractors and self-propelled machines where it takes too long to inflate the wheels with the standard air compressor. The unit is characterized in particular by its compact design and low power requirement.

Multi-cell compressor, pmax: 7.5 bar

Effective delivery rate: 1,800 – 2,000 l/min (at 4 bar back pressure)
Oil requirement of the hydraulic motor: approx. 55 l/min.

AIRBOOSTER®plus

AIRBOOSTER®plus

Tire inflation and deflation set for all agricultural tractors and vehicles

The AIRBOOSTER®plusis a portable and extremely robust system for quickly adjusting the tire pressure while stationary. The user can adjust the tire pressure in a tire very quickly using the associated hand-held device (pressure gauge with ball valve and connections). This makes it the ideal product for anyone who only wants to change or check the tire pressure from time to time.

  • Can be used immediately after fitting the PTG screw-on nipples
  • Deflate in one minute, inflate in two minutes (per wheel)
  • Pressure adjustment in the range 0 to 3 bar
  • Unbeatable price-performance ratio
