Static from sandblaster

[TheClaw]

We are getting a lot of static from our sandblaster while operating it. This is my son, he's standing on a foam HF mat and rubber soled shoes. he gets a little jolt from the screws on the glove rings if his arm gets to close to the box when he's blasting. The vacuum is also running.




It's not alot, but its anoying and static like that with all the fluids in the garage will get us nominated for a Darwin award.

Any suggestions?

Skat Blast® Anti-Static Kit

Get the Skat Blast® Anti-Static Kit and eliminate static in your bead blaster cabinet! During the abrasive blasting process, abrasive flows through the rubberized suction hose in the cabinet. This rubberized hose is nonconductive and can cause a static charge to build up within the cabinet...

The cabinet is grounded. The problem is making sure you are at the same potential as the cabinet. Standing on the mat and wearing shoes is just making the situation worse.

Ground the gun and/or wear a grounding strap bonded to the cabinet.

I have the same cabinet call TIP and I ordered the kit for that, grounded the gun and stand on a mat haven't had a problem since. It is annoying

Cabinet is on rubber feet.

Ok, stupid question #2, before spending money, would a ground from the Cabinet to some nearby conduit be ok?

I suspect you have the cabinet grounded one way or another. Usually I see a light, blower, or something that is grounding the cabinet but yes, you can tie the cabinet to anything.

Bonding the gun is going to be the ticket here. If that's out of the budget the anti-static strap bonded to the cabinet is the next cheapest option.

The electrical outlets that I have installed in metal boxes, automatically ground to the box and hence to the EMT conduit. If your setup is similar, then yes, you can ground the cabinet or gun or whatever to your metal conduit. I suppose there might be some vintage outlets that don't do this, so I can't say for 100% certain that it will work. You do have a 3 wire electrical system, right?

My last shop had a large **** Blast cabinet, getting a shock on your pecker was should I say interesting.

The flow of abrasive and the air extraction flow builds a static load in and on the cabinet. When standing on the mat you are isolated until you get close to the cabinet. A static strap to the cabinet or keeping your body against the cabinet before beginning blasting will usually solve this. Blasting a plastic piece will really light you up. My cabinet size is such that I can keep my chest against it while in use. No issues since I learned to do that.

Need the operator to be bonded to the cabinet

I get shocks using my SkatBlast too.
Mine is larger but still metal housing and my arms easily go into the gloves further.
Extended use I get a black and blue like bruise inside my left arm from the shocks.
Never really cared to resolve the issue.

I have added metal electrical boxes on back for a receptacle to power on the lights and Vac at same time. So it is essentially grounded to the electrical system. But I am not.
My dust collector has been modified after the motor on top burned out. 3D printed a hose adapter on top to just use a $30 Hart shop vac now.
The cabinet was free. I did ad the Eastwood gun and foot pedal and found a deal on a filter to replace the rotted original, why the motor burned out...
