Tumbler & Supplies

* You are purchasing a dual tank tumbler which will allow you to roll 2 tanks at the same time

* This tumbler will work with cylinders with a length of up to 34 inches and will fit any cylinder with a diameter of 8.25 or smaller 

* This machine consists of two heavy gauge, dichrome-plated steel end plates that support three parallel rubber rollers, the center one of which is rotated by a 60 rpm, 1/4-hp gearmotor.

* This tumbler allows two dive cylinders to be simultaneously tumbled at about 25 rpm.

* The semi-soft rollers will not deface or mark tanks, but still have excellent traction.

* The spacing between each roller axis is adjustable so tanks of different diameters can be accommodated.

* The parallel side rollers are offset in height from the central drive roller which also promotes handling tanks of varying size.

* The tumbler is easily assembled and can be anchored to a bench, floor, or fabricated frame.

* NOTE: An exploded parts diagram/instructions are included or available at our website www.global-mfg.com.

** Electrical connections are not included.

* Supplied with a 110v motor only.

** Shipped in 2 boxes

* Roughly: 47" inches long ...22" Wide by 9" inches tall 

Ships unassembled, in a box that’s around 41" x 11" x 5", and the motor ships alone in a box (12" x 10" x 7"). 

* You are purchasing a Tank Drying Stand    

* This is a sturdy 3-legged steel frame which holds all common size SCUBA cylinders in an inverted position so that after tumbling, media and cleaner can be drained from them into a receptacle.

*The stand will hold tanks up to 8.25 in diameter.

* You are purchasing 1 pound of glass balls for tumbling your cylinders

* Glass Beads are 4-5 mm clear glass balls which are employed whenever minimal cutting activity is required such as during oxy-cleaning for Nitrox usage or for removal of persistent internal tank odors.

* NOTICE: Glass Balls will not remove heavy, gross contaminants.

* You will need about 10 pounds of these glass balls per tank!

* Remember you are purchasing by the pound so if you want 10 pounds you would enter 10 at the add to cart area

*You are purchasing 1 pound of Aluminum Oxide Media for cylinder tumbling

* Aluminum Oxide Media chips are small, hard, randomly-shaped abrasive particles which will loosen scale and rust from tank walls, thereby augmenting the action of solvent chemicals to remove/suspend internal contamination.

*This media can be used in steel or aluminum tanks and with various adjunct solvents EXCEPT TANK ACID which will attack the chips and produce excessive gassing.

*Aluminum oxide has been successfully used for tank tumbling for 40 years.

* We suggust you use 25-35 lbs. per tank while tumbling

* Ceramic Chips are cylindrical, cast resin pellets with a computer-designed shape for specific cutting activity.

* Each pellet (5/32" OD x 5/16" long) contains an abrasive agent which gives a very precise, predictable cleaning action.

* More tolerant of acid than aluminum oxide, ceramics are very useful for tumbling aluminum tanks or for oxygen-cleaning operations.

* We recommend you Use 25 - 35 lbs. per tank for tumbling!

* You are purchasing 1pound of ceramic media so if you want 25 pounds you would enter the number 25! 

*This tank dryer system can hold two dive tanks in an inverted position so that they can be dried after tumbling by forced hot air.

* Includes two tank stands, an air delivery pipe with two outlet ports, and an industrial-grade heat gun.

* New heat gun with the dyer system

* One outlet vent on the air manifold is interchangeable into a smaller diameter pipe for drying older steel cylinders with 1/2" - NGT openings.

* NOTE: Care must be exercised NOT to over-heat aluminum tanks during drying. Our dryer's design makes over heating unlikely, but 325 F or more can impair a tank's tensile strength. See dryer manual, tank manufacturer's specification 

* This is the dryer heat gun for our drying stands

* Special, small stainless brushes for removing those stubborn deposits on the very bottom of dive tanks.

* Each brush screws onto a 3 - foot aluminum rod which fits into any 3/8 electric drill.

* Each unit comes with the brush, extender rod, and a plastic guide sleeve to augment insertion through tank necks.

* Fine wire for light rust sports in steel tanks or Bayerite deposits in aluminum models.

* Will not seriously damage the interior coatings of aluminum tanks.

* Special, small stainless brushes for removing those stubborn deposits on the very bottom of dive tanks.

* Each brush screws onto a 3 - foot aluminum rod which fits into a 3/8" electric drill.

* This kit comes with the brush, extender rod and a plastic guide sleeve to augment insertion through tank necks.

*This Heavier, stiffer wire for use on the bottom for flash rust or other hard deposits in STEEL tanks.

* Not recommended for Aluminum models.

* Heavy-Duty Bush - without Rod Special, small stainless brushes for removing those stubborn deposits on the very bottom of dive tanks.

* Each brush screws onto a 3-foot aluminum rod which fits into any 3/8 electric drill.

* Each brush comes with the brush and a plastic guide sleeve to augment insertion through tank necks.

*Light-Duty Brush - without Rod Fine wire for light rust spots in steel tanks or Bayerite deposits in aluminum models.

* Will not seriously damage the interior coatings of aluminum tanks.

* Special, small stainless brushes for removing those stubborn deposits on the very bottom of dive tanks.

* Each brush screws onto a 3-foot aluminum rod which fits into any 3/8 electric drill.

* Each brush comes with the brush and a plastic guide sleeve to augment insertion through tank necks.

* A fine, sand like abrasive grit which speeds the cleaning activity of normal media in STEEL tanks and usually shortens the tumbling process by several hours.

* Also enhances the cleaning of very dirty tanks with pitted or concreted walls.

* Requires only 2-3 teaspoons of grit per tumble.

* Sold by the pound.

* Just the tool to remove congested media from a dive tank after turnbling.

* Snap this air gun onto any pressurized BC hose, place the curved tube nozzle into the neck of the tank which is inverted over a catch pan, and inject a stream of air.

* The internal pressure created will quickly jet a slurry of liquid and media into the pan, emptying the cylinder in seconds.

* A chrome-plated 1.5" hexagonal brass block with 6 machined grooves which can be used to estimate the depth of pits in dive tank walls.

* Slots ranging from 0.01" to 0.06" deep can be used as a reference after the depth of the pit has been probed.
