Wet Blasting Before & After

The Mr Hard Water Wet Blaster Is Ideal For:

Pool Cleaning Professionals |  Equipment Rentals | Construction Supplies | Farm and Equipment | Government | Marine Boatyards | Pool Supplies


First, add media to the hopper of the wet blaster.  Second, attach the blast gun to your pressure washer.  Third, select either the standard gravity fed mode or the turbo air boost mode by adjusting the valves on the Venturi Assist Carburetor (VAC).  Fourth, begin wet blasting, sand blasting, or soda blasting.


Its dual-mode operation is user adjustable and offers two functional modes of operation.  In traditional mode, it operates as a gravity fed hopper.  The only action on the media results from the venturi blast head which pulls it through the hose and to the work surface.  Resisting this action is the weight of the media and the friction in the hose and the hopper causing intermittent flow and shorter work distances.  To offset these forces and to smooth out the media flow over longer distances, we use a Venturi Assist Carburetor (VAC) in turbo mode. 


Connect the VAC to the air compressor. Use the built-in step down regulator located on your air compressor to supply to 1 – 15 psi stable air pressure to the Venturi Assist Carburetor (VAC).  This will push the media from the hopper to the work surface while the venturi blast head pulls it.  (PUSH/PULL) The air pressure will depend upon the weight of the media and distance to work surface.

The operator adjusts the strength of the cleaning, stripping, and degreasing by using different types of media at different water pressures supplied by a power washer (3800 PSI / 3.5 GPM – 4200 PSI /4.0 GPM).  Media Sifter included.
