Applicable to box manual sandblasting machine and box type automatic sandblasting machine.
Can be used for sand glass,sandblasting,surface polishing processing,machinery parts.
A blast nozzle accelerates the air and abrasive as the mixture exits the end of the hose.
The taper and length of the nozzle's inlet and outlet determine the pattern and velocity of the abrasive exiting the nozzle.
The composition of the liner material determines its resistance to wear.
Designed for surface cleaning,rust removal and glass,aluminum alloy and other decorative surface sandblasting,marble engraving.
Specifications:
Condiiton: 100% Brand New
Material: Aluminum + boron carbide
Color:Black + Sliver
boron carbide Nozzle Internal diameter:8mm
Operation:
1.The operator inserts the nozzle washer into a contractor-thread nozzle holder and screws in the nozzle, turning it by hand, until it seats firmly against the washer.
2.With all related equipment correctly assembled and tested, the operator points the nozzle at the surface to be cleaned and presses the remote control handle to begin blasting.
3.The operator holds the nozzle 18 to 36 inches from the surface and moves it smoothly at a rate that produces the desired cleanliness. Each pass should overlap slightly.
4.The operator must replace the nozzle once the orifice wears 1/16-inch beyond its original size.
Package includes:
1 x Air Sandblaster Gun
1 x Boron Carbide Nozzle

HF blast cabinet. Modified to gravity feed. I was not getting enough performance from the gun that came with the cabinet and I wanted foot pedal control. After looking at all the reviews for other guns on Amazon They seemed to have either marginal performance or a high price. This one is inexpensive and had good reviews. I believe the 1/4" port foot pedals on Amazon do not flow enough air for blast media unless you are just etching glass. I built a foot pedal using a 3/8" ball valve. With this combination I can quickly remove rust, heavy scale, paint and even powder coat.

Be sure you adjust the air nozzle in or out until you get good media flow.Works well. I hope it lasts and I can find nozzles for it.

As many other people have stated these WILL NOT work at all right out of the box. You MUST install a washer directly behind the boron nozzle to prevent it from sucking backward and stopping all flow. Once you get that corrected it will work very good.

I just bought this, installed it in my blast cabinet and tried it out. Well nothing happened, So I pulled the gun apart and found that the air nozzle had not been through drilled when it was made. I drilled it out to the diameter of the nozzle end to that size. Once I had it drilled and back together it was a great blasting gun. I have had issues with my blasting media not being lifted up to the gun. I found that there were no issues with this unit and it flows significantly more than my previous $110 gun. I was able to reduce the pressure and had more consistent and uniform blasting patterns, no more streaky lines on the parts. This has saved me lots of time standing around waiting for my parts to cleanup. I am running a deep well blast cabinet with 80grit Al oxide and a twin piston 12cfm compressor. I will say this seems to require a good amount of air flor but less pressure. I think it would do a great job with vapor blast cabinets or even spraying masonry coatings or stucco and plaster.It has a plastic housing for the blasting nozzle which would likely be better for wet operations, but also looks like It can hold a wide variety of nozzle sizes. 4 stars because I had to fix it right away, but otherwise its 5 stars for the price.I would suggest this to a friend or other people Microsoft thinks would enjoy their operating systems.

Good cheap gun. Recommend to drive a roll pin into the air jet to reduce the volume of air so compressor can keep up.

Upgraded my harbor freight blast cabinet with this gun and it’s a night and day difference

Product is poorly made . It cannot be attached to pressure washer wand firmly . Only way to use us a length of rubber hose attached to the Barb fitting which causes it to flop around and become useless at directing the blast to where it's needed . I wouldn't suggest this product to anyone.
