Arms Working elevators offer compressors on carts towed on cars. Two types are available. The smaller one is 7 bars (2.4 m3 and 40 l/s) and the larger one is 10 bars (3.7 m3 and 63 l/s). The presses are powered by a diesel engine that has an electric start. Both models have an air hose on a roller that is 25m long. Additional hoses can also be provided if needed. An iron nozzle compressor can be obtained, which is used, among other things, to clean clappers and other surfaces.
