FAQs
- What is a stationary high pressure cleaner used for? A stationary high pressure cleaner is a wall or floor mounted machine designed for continuous, heavy duty cleaning in workshops, warehouses, agricultural sheds and vehicle wash bays, where a fixed installation suits regular daily use.
- What working pressure do industrial pressure washers operate at? Industrial cold water pressure washers typically operate between 50 and 200 bar, with some models reaching higher maximum pressures for stubborn dirt, grease and grime on tough surfaces.
- Do stationary pressure washers require three phase power? Many higher output stationary pressure washers run on three phase power to deliver the motor output needed for continuous heavy duty operation, so an appropriate power supply should be confirmed before installation.
- How much maintenance does a high pressure cleaner need? Routine maintenance generally includes checking the oil level, cleaning or replacing the water filter, and inspecting hoses and fittings, which keeps a stationary pressure washer running reliably with minimal downtime.
- Can a pressure washer be permanently mounted to a wall? Yes, many stationary pressure washers are supplied with a sturdy frame designed for permanent wall or floor mounting, making them a practical fixed cleaning station for busy commercial sites.
