EXAIR Products Help Clean a Sandblasting Room

I’m sure there are any number of things that you could do incorrectly running a blasting room, but I became familiar with one failure mode this week: Clean Up.

I don’t know much about blasting rooms, but I know folks usually say this when it’s over –  clean up! That is a phrase I have heard once or twice in my life. We had a customer call in this week, who ran large pieces, one at a time through his sand blasting room, and needed to clean up after each operation. He had used electrically powered industrial vacuum cleaners in the past, but they did not hold up. He had a cyclonic separator in place, but enough dust and debris passed through the separator and into the impellers to create a maintenance nightmare. The problem had gotten so bad that before calling us he was using a broom and scoop method. The clean up was taking longer than the process, which made him unable to meet their production schedule, when the vacuum was down.

EXAIR’s solution the Heavy Duty Dry Vac (HDDV), model 6397. The HD Dry Vac fits onto a 55 gallon drum and uses compressed air to create a powerful vacuum, capable of moving over 50 pounds of ceramic tumbling media per minute.  The 6397 comes with a drum, drum dolly, 20 feet of compressed air hose, heavy duty accessory kit, and 10 feet of static eliminating vacuum hose, which allows the HDDV to clean easily in a 25 foot radius. Large enough to reach every corner of the customer’s 25′ X 25′ room.

I thought this would be great solution to the customer’s problem, but of course, the customer had one more wrinkle in his process.  His hopper for the blasting media was on the roof of his sand blasting room 12 feet in the air, and he needed to recycle the blasting media he collected. I can understand not wanting a new process to lift a 55 gallon drum up to the roof of his sand blasting booth after every part. Unfortunately, the HDDV, model 6397 would not be the best solution to vacuum and convey the blast media back into the hopper – but we do manufacture a solution, the EXAIR Line Vac.

The Heavy Duty Line Vac, model 150200, can easily transfer product up 12 feet in the air. After cleaning the floor of the facility, the customer setup a conveyance station with a 2″ Heavy Duty Line Vac to move the material to the hopper in the top of the roof. We were able to reuse the cyclonic separator he had from his electric vacuum to contain the material and release the air that is moved through the 2″ Heavy Duty Line Vac.

After using the EXAIR product, his cleaning time greatly decreased  Also, the Spill Recovery kit that comes with every 6397 Premium Heavy Duty Drum Vac greatly reduced the wear and tear on the employees backs and knees.  Finally, he effectively recycled his blast material with the 2″ Heavy Duty Line Vac air operated conveyor system.
