Oils, chemicals, dirt, liquids and more can’t go straight into the sewerage system without first being filtered with specialist equipment like Oil Water Separators.

In addition to the physical Wash Bay or Pad you’ll often need professional grade Pressure Washer Equipment that can be electricity or 3 phase powered or run on petrol or diesel engines as required. Hot and Cold Water Pressure Washers and noise reducing models are available for many different installation requirements.

Depending on your needs and your Local Authority rulings you can install Roofed or Unroofed Wash Bays Outside say in a Car Park or inside a Factory or Warehouse Wash Bay installation.
