Wetblast Injector System

Clemco’s Wetblast Injector System adds the dust-suppressing power of water to any pressure blast machine. The Wetblast injects a small amount of water into the high-velocity abrasive/air stream just before the nozzle.

This hard-hitting mixture of water and abrasive cleans and keeps dust levels under control.

The Wetblast System introduces water into the abrasive/air stream before it passes through the nozzle orifice.  This results in a complete wetting of each abrasive particle, unlike with water ring systems. The Wetblast controls airborne dust far better than water ring systems.

Operation
The power behind Clemco’s Wetblast Injector rests in our exclusive 10:1 pump.  It uses compressed air to inject water into the high-velocity abrasive/air stream at the nozzle.  A single pump can easily operate two nozzles, each with independent controls.  Simply purchase an additional nozzle adaptor and add one more hydraulic hose to the water outlet.

The Wetblast Injector System requires no electric power, so there are no wires and no connections to short or shock.

Because the Wetblast Injector has its own pump and uses relatively small amounts of water, any source of clean water will work — household tap, water tower, or low-lying tank.

A regulator and pressure gauge, mounted inside the control box, controls water pressure.  The operator adjusts the water volume with a fine-thread needle valve at the nozzle.

The versatile Wetblast Injector lets the operator blast with wet or dry abrasive. When the machine is equipped with an abrasive cut-off system, the operator can rinse the surface with air and water, then dry the surface with high-pressure air.

Applications
A blast system with Clemco’s Wetblast Injector quickly cleans structural steel to any degree of cleanliness from brush-off to white metal.  After blasting, the water-and-air rinse removes soluble salts and other corrosives that can cling to the surface.  If flash rust is a problem, the pump can siphon clean water from a static-holding tank that contains a premixed rust inhibitor solution to retard rust development on exposed steel.
