Skat Blast Abrasive Blast Cabinet FAQs
Carburetor before and after sandblasting.
A Skat Blast Cabinet is an enclosed system for cleaning parts. Just place the parts on a work screen within the blast cabinet and use the built-in gauntlet- type gloves to hold parts and direct the Power Gun. Abrasive “blast” from the gun quickly removes all rust, paint, and scale, leaving a satin finish ready for paint or further preparation. Add your choice of abrasive by pouring it through the side door. Keep funnel about 1/3 full of abrasive and do not overfill, as abrasive will compact and not flow properly.
When media blasting, abrasive drops to bottom of funnel and is continually recycled each time foot pedal or trigger gun is pressed. Abrasive is picked up automatically and used over and over again, leaving a beautiful satin finish on your parts. Eventually the abrasive wears out, turning to a consistency of powder and must be changed. It is not practical to blast with worn out abrasive. Once the abrasive breaks down, blasting results are poor and cabinet visibility is greatly reduced. For best results, change abrasive on a regular basis and keep the window clean at all times. A “peel off” inner lens protector is included with our cabinets and replacements are available at extra cost.
Every Skat Blast Cabinet comes with a detailed set of Instructions, which will guide you through the initial setup and get you going quickly. Instructions are well-illustrated and lead you through the process – from hookup to your air supply, to operation of the unit. Instructions have photographs and diagrams to show you how to complete installation of the Power Gun and Vacuum or Dust Collector hook-up. If you need technical help or assistance in getting started, call TP Tools Tech Line at 800-321-9260. A knowledgeable technician will guide you step-by-step in minutes. When you call TP Tools, you will talk to a live person in Canfield, Ohio, not a recording. Best time to call our Tech Line is from 9:30 AM to 5 PM weekdays.
All Skat Blast Cabinets require a supply of compressed air. Our normal (Medium Nozzle) setup requires from 10-15 cfm air at 80-100 psi. Normally a good 5 HP 2-stage Air Compressor will handle most of our cabinets (check the cfm rating of your air compressor). If you are low on air, we can supply a “low air supply nozzle/air jet setup” extra cost, enabling you to blast, but at a slower pace.
Air from your compressor is routed to a convenient location in your shop, and we highly recommend an air filter, moisture separator and pressure regulator, so that air to the cabinet is clean and dry and set to the correct operating pressure for your particular application. We furnish a short whip hose (with 1/4″ male pipe threads) to lead from the Power Gun (inside the cabinet) through an opening in the front of the cabinet and to either a Foot Pedal Control or to your air hose.
Keep your Skat Blast Cabinet connected to your air supply, so it is always ready for use. Cabinet uses no air or abrasive except when actually in use. When you want to clean a part, cabinet is ready whenever you are, at a moments notice.
Glass Bead is a type of abrasive made primarily from soda-lime glass. It looks like salt or sugar and is a favorite abrasive for use in cabinet blasting, giving a satin finish to metal.
See “Abrasive” section of this site for description of many abrasives that are suitable for use in cabinet blasting. Glass Beads and Skat Magic are preferred for most automotive components: fuel pumps, carburetors, valve covers, nuts and bolts, but any abrasive can be used. You can easily change the abrasive through the spring-loaded trap door at the bottom of the cabinet funnel. You can also use 1st Choice, Speed Bead, or most any other abrasive. Skat Blast has now developed a new Soda Blast Attachment that can be fitted to most of their cabinets. For information on Soda Blasting, ask for a Free Catalog from TP Tools by calling 1-800-321-9260, or checking the TP Tools web site at www.tptools.com.
Simply pour in through side or topload door. We suggest pouring abrasive through a Sifter Screen to remove impurities. Normally the funnel should be filled to about the 1/3 full mark, as adding too much abrasive can result in compaction of the abrasive and poor flow.
All Skat Blast Cabinets recycle automatically, so abrasive can be used again and again (exception Soda Blasting, which is a one-time process). Eventually, the abrasive will break down and turn to “dust”. At this time, it must be replaced. Worn abrasive does not cut well and creates poor visibility. It is not economical or practical to attempt to blast with worn out abrasive.
When you press the foot pedal or pull trigger of power gun, abrasive is pulled up through the pickup tube, through the siphon hose and to the power gun where it hits the rusty object. Abrasive then drops through screen and into the funnel for recycling on a continual basis until abrasive finally breaks down and must be replaced.
The Pickup Tube is one of the most important components in a cabinet. Skat Blast has developed a high velocity, dual pickup tube with controlled openings to provide more power and eliminate “surging” during operation. You get a smooth, even flow of abrasive to the Power Gun at all times. Pickup tubes should be replaced occasionally as they will wear the same as the nozzle itself. We suggest annual pickup tube replacement for average shops.
The Blast Cabinet Power Gun holds the nozzle and provides the abrasive blast. Skat Blast Power Guns have large, direct air passages, resulting in better suction and blast … true high velocity. This Blast Cabinet Power Gun has a mixing chamber that mixes the air with the abrasive. Air is forced through a small orifice air jet, which intensifies as it passes through the mixing chamber of the Power Gun. Abrasive is pulled into the Power Gun from the funnel of the cabinet through a clear siphon hose from the Pickup Tube. The abrasive is then mixed with the incoming air, and exits the Power Gun through the nozzle, removing rust, paint and scale efficiently. Abrasive spray is confined to the inside of the cabinet and after hitting the object being blasted, drops into the funnel where it can be used over and over again. Eventually this abrasive breaks down into dust and must be replaced.
The inner nozzle holder of our Blast Cabinet Power Gun has a case-hardened steel insert for long life. This is important, since the nozzle holder is exposed to the abrasive stream and softer metals wear quickly. Power Guns in Skat Blast Cabinets are Made in USA and are built to last for many years, although nozzles and air jets must be changed on a regular basis. For high-volume users, we supply extended-life nozzles made of tungsten carbide. Steel or Ceramic Nozzles are suitable for light-duty work, with the Ceramic Nozzles lasting considerably longer than steel. (Nozzles and all parts can be shipped UPS the same day from TP Tools).
Most smaller blast cabinets include trigger guns. Larger cabinets usually include a Foot Pedal Control. When you pull the trigger or press the foot pedal, the result is the same: abrasive is pulled up through the gun and “blasted” at the part, instantly removing rust, paint, and scale. The results are the same, but for more than occasional use, we recommend the use of a foot pedal control to minimize operator hand fatigue.
The nozzle and air jet size determines the air requirements. The air jet fits inside the power gun and controls the amount of air leading to the nozzle. Nozzles and air jets can be changed, depending on your air compressor. If you have a 3 HP compressor (7 cfm), your best choice is probably the small nozzle. If you have a 5 HP compressor (10-15 cfm), use a medium nozzle. For a 10 HP or larger compressor, use a large size nozzle. Remember, nozzles and air jets must be changed in sets (small with small, etc.) and are available in steel, ceramic and carbide. Nozzles and Air Jets are always in stock at www.tptools.com
Blast cabinets require a vacuum to remove dust created in blasting and improve visibility. For smaller cabinets (SC-28 and under), a shop vacuum can be used. However, these vacuums have a small filtering area, so visibility may be reduced. Also, abrasive can work into filter, causing motor damage or failure. For more than light work, we recommend our Vac-50 HEPA Vacuum. For commercial or industrial use, we recommend our Dust Collector systems to remove dust while cabinet blasting. All of our Vacuums and Dust Collectors are also Made in USA and are very quiet in operation. A “Final Filter Outlet Kit” is available at extra cost for any of our Vacuums or Dust Collectors to prevent dust from escaping into the room in the event of a worn-out vacuum bag. More information is provided at www.tptools.com.
A fluorescent light provides dim lighting inside the cabinet. A floodlight is better, in that an intense beam of light is directed at the part. This is similar to fog lights in a car, which penetrate through the fog. All Skat Blast Cabinets use a floodlight for improved visibility. Floodlight bulbs are available at any local hardware or lighting store, saving you a lot of time when it comes time to replace the bulb.
Superior operation is determined by the type of pickup tube, power gun, vacuum system, funnel angle, door seal, method of holding lens and gloves, etc. (Skat Blast Cabinets are fully assembled, feature molded holders for both lens and gloves, and do not leak.) While not always visible, these features make a better product. We have thousands of satisfied customers all over the world. Over 40 years of building a successful product is your assurance that a Skat Blast Cabinet will provide the help that you need on a steady basis.
Beware of the word, “Kit” or “K.D.” in cabinet ads. Usually, you receive a “knock down” unit: steel panels, hundreds of rivets, bolts, nuts, hinges, caulking, etc. These kits can cost as much as a fully assembled cabinet, and you have to build the unit yourself, which can take hours (sometimes days) to assemble. Compare specifications and price. You’ll find a fully assembled cabinet from Skat Blast is a better investment — Years of experience in building a trouble-free abrasive cabinet have been proven to satisfied users all over the world.
