Trailer Engineering also offer the Rainmaker / Pressure washer combination which is a NEW and innovative product to the dust suppression industry, offering a budget alternative to the very expensive dust cannon and dust fan machines. This is a customised version of the standard 3000 psi diesel pressure washer water bowser and comes with the Rainmaker fitted onto the pressure washer for a controlled suppression of dust, perfect for building and demolition sites. This multi functional water bowser only uses 15LPM at any time. If you already have a pressure washer and would like to convert it, Trailer Engineering also offer a retro fitting kit for the Rainmaker which comes with the Rainmaker mast and spray nozzles, two way high pressure valve, high pressure hose and connections. Trailer Engineering's Rainmaker can be fitted to any 3000 psi pressure washer with this kit. See the Rainmaker in action in the videos below.
