Water blasters don’t get much more rugged than this…Mounted in an industrial roll frame to protect your asset from accidental damage this unit comes with a lifting point so it can be hoisted easily in and out of vehicles. The industrial GX Honda motor is coupled to a low speed Italian pump to provide consistent high pressure and flow so you can get your cleaning work done quicker. Putting out an impressive 4000psi and 21 l/min this water blaster is ideal for industrial wash down and maintenance work. The robust, high quality nature of this unit means you can rest assured it won’t let you down! The HH4021 water blaster is a worthy investment for anyone in the contract cleaning business. Note: Kerrick can customize flow, pressure and layout/mounts to suit your needs.
