Gear reduction box
The PA B5 gearbox can work with powers up to 4.8 Kw. The ease of assembly allows a quick connection between the engine and the pump, giving rise to a compact unit entirely supported by the engine. The universal flange on the engine side allows the use of the B5 with the most common petrol engines on the market. PA gearboxes are normally used on professional petrol high pressure washers.
