It can be used on thick steel down to thin delicate steel boat hulls and brass paint removal. There’s a flow control tap so you can adjust the water flow to the amount of water you require. You can also adjust the flow control valve at the air pump this gives you the ability to speed or slow the pump up or down so you can add more or less water into the air stream. These blasters are great for use in boat yards due to its 100% dust suppression and the ability to be pushed around the work area.

These blasters are also great for blasting delicate car shells or thin steel at low pressure due to the water keeping the area that you are blasting cool this stops the steel warping.
