THE AIRLESS TUMBLAST
The efficient blast cleaning
The heart of any airless blast cleaning equipment is the
abrasive throwing unit. The 27" x 36" Tumblast uses the type
"Q" wheel (15" diameter x 2 1/2" wide) that hurls abrasive by
controlled centrifugal force upon the work to be blasted.
This wheel features blades held in position with a spring clip
The Type "Q" Unit
HOW THE WHEEL WORKS
Gravity-fed abrasive is picked up by the rapidly rotating
impeller and discharged through openings. It is then forced
through the opening in the stationary (but adjustable) control
cage and immediately picked up by the rotating blades.
Blades repeat this operation approximately 300 times a
second. The abrasive slides along the blades until it leaves
the wheel in a controlled barrage of high capacity cleaning
