Abrasive Blasting Cabinets, Dust Collectors, Vacuums & HVLP Paint Spray Systems
HOW TO INSTALL CORRECT METAL PIPING IN YOUR SHOP
When we first moved into our Canfield, Ohio plant, we installed all of our air lines with metal piping, being sure that the pipe size was correct for our needs, and correctly designed so that moisture in the air lines could be easily removed with water separators and drain valves. This is a necessity when operating any type of abrasive blasting equipment, plasma burning equipment or simple air tools. To see a very detailed piping diagram and other information on airline accessories, parts and fittings, please see:
One of our customers (Mr. EZ of Ringgold, Georgia) used the above piping diagram and airline accessories to install a neat airline piping system in his shop. Shown below are three pictures of his shop. Take a careful look of how the piping was installed with "risers" to keep the moisture within the metal pipes until it can be removed with our water separators and drain valves. EZ even has a neon "Open Sign" to welcome visitors.
Center picture shows the best way to install such piping. The main air line from your compressor runs horizontially across the walls of your shop. At each airline hookup station, the pipe drops down towards the floor with a drain valve to blow water out of the piping as shown. You can place a bucket under this pipe to catch the water when valve is opened. Just above this drain valve is a short length of pipe stubbing out horizontially and then an elbow facing up and another elbow facing to left. This section of piping is called the "riser" and is very important, as we are using gravity to keep the moisture within the piping below this area, so that most moisture can be removed when opening the drain valve (suggest daily).
Air is then directed into a moisture separator and then to an airline regulator, whch is used to regulate the air pressure from your main line to whatever pressure is to be used for your particular application. For most abrasive blasting in a Skat Blast Cabinet, we recommend 80 to 85 psi, as higher pressures will pulverize the abrasive on impact, eventually turning the abrasive into a powder form, which will not blast effectively, and will also create much dust within the cabinet, resulting in poor visibility. Looking at the above setup, see that EZ installed two moisture separators. Not a bad idea, although we would recommend that the second separator be a Coalescing Filter, which is the best choice for a final airline filter.
*Note: There are exceptions to the above suggestion as to pressure. If using "First Choice" or other lower cost abrasives and are blasting very rusty objects such as wheels or some heavy steel automotive components, you may want to increase your pressure above the recommended 85 psi. It will cut faster, but the abrasive will break down quickly, resulting in the necessity of changing your abrasive more frequently. Blasting with worn out abrasive is never satisfactory, as results and visibility will be poor.
Abrasives should be change on a regular basis and we offer many choices for various projects that you might need. See other section of this web site by clicking "Abrasives" at Home Page.
WARNING: Do not use Silica Sand for abrasive blasting, even within a closed cabinet. Sand is a severe health hazard, as operator is always exposed to dust when loading and unloading cabinet. Also sand breaks down quickly on impact & turns to dust quickly, so visibility is poor.
WARNING: Do not install any airline piping with PVC or plastic piping. Even though it may be rated at high pressure, it is unsafe and is banned in many states. Reason: should the PVC piping get damaged on impact for any reason, it will shatter and "explode", sending pieces of plastic in the form of shrapnel in all directions, with a strong possibility of personal injury. As an example, if you bump the PVC piping with a cart or any object, it will break. This is even more likely in colder climate areas. We have also heard reports of PVC piping systems failing after a few years, due to a deterioration of the inside surface of the piping from the oils that are commonly within air lines that come from your air compressor. There is a new type of plastic piping now being sold by TP Tools that has metal reinforcement built into the inside of the plastic to minimize danger of breakge under impact. Call TP Tools for more information on this new product.

"BUILD YOUR OWN CABINET KITS" are available.
These are described in TP Tools Catalog in detail at www.tptools.com
See below for a really professionally built cabinet that was made by one of our customers (Ken D, Westminster, MD). Using Skat Blast Plans and components and ordinary plywood and some metal legs, Ken was able to build a cabinet that will serve him well for many years. The nice thing about using Skat Blast componets is that they are always available at TP Tools in Canfield, Ohio for immediate UPS shipment. This means no down time.
Side view of Ken's Cabinet. Notice that he used two door latches, which is always a good idea to keep the dust created in blasting where it belongs. Floodlight was installed in the upper left hand corner - out of the way, but aiming at the work area in front of the gloves. Switch and duplex receptacle is on top left of cabinet and turns on the floodlight, and a vacuum can be plugged into the outlet. Ken opted for a foot pedal operation and added a very useful accessory - a blow gun inside the cabinet to blow dust of the surface of small parts. This is evidenced by the two air hoses entering the cabinet on right front (one to power gun and one to the blow gun).
Other then the legs, the entire cabinet was made of plywood. The lens, lens trim and glove and glove flanges were purchased from TP Tools at moderate cost. Joints were neatly aligned and sanded to where they cannot be seen and the cabinet was painted with light gray enamel, close to the standard color used by Skat Blast. If you look closely, you can see the inner lens protector, which is attached to the inside of the tempered glass lens. This protector is made of durable Mylar and can be changed as it gets scratched from blasting. These are sold in convenient packages of three and are always in stock at TP Tools in Canfield, Ohio
Front View, showing Power Gun and Blow Gun. Metal framework attaches to the wooden cabinet with either wood screws or bolts and nuts. Notice electrical outlet with switch at top left, which can be used to turn on the vacuum and light. A very professional job and with Skat Blast plans and components, you can make this very same cabinet, using regular carpenter shop tools. Not shown in this picture is a trap door at bottom of funnel, which is used for dumping used abrasive. This is available at TP Tools and is spring-loaded to keep it closed. Always remember to change abrasive on a regular basis, as blasting with worn out abrasive is one of the main reasons for poor visibility inside a cabinet, as well as not being cost effective, due to slow results. Most any abrasive can be used in this cabinet. See other section of this web site for a description and pictures of available abrasives that are in stock.
Side View - If we didn't know better, we would think this was one of our Skat Blast Cabinets! It is identical in appearance to our cabinets, including Gloves, Lens, Floodlight and Work Area Sscreen. As you blast, rust and paint are instantly removed and drop to the bottom of the funnel, along with abrasive. When foot pedal control is pressed, air passes through the power gun at about 80 PSI and pulls the abrasive from the bottom of the funnel and injects it into the air stream. This powerful blast removes paint, rust and scale quickly and efficiently. For small parts, we recommend the use of a hand-held "Bolt Basket" that holds the parts so that they do not become lost. This is not shown in this picture and if Ken doesn't have one of these, you can be sure that we will send one to him quickly. As you blast, the abrasive mix can be used over and over again until it turns to dust. At that time it should be replaced.
Congratulations Ken on building one of the nicest cabinets that we have seen, although there are undoubtedly many other similar cabinets, as we have sold thousands of "Build Your Own Kits". These kits are available in several types:
a) Trigger Operated Kit includes Trigger Gun, Pickup Tube, Siphon Hose and Air Inlet Hose, along with a clearly illustrated set of Instructions and Plans. Extra Nozzles are included.
b) A Foot Pedal Operated Kit includes all of the above, except that a Foot Pedal Control is included, and gun does not have trigger. This type of setup eliminates operator fatigue when pulling trigger for extended periods of time. Extra Nozzles are included and long-wearing Ceramic or Tungsten Carbide Nozzles are available at extra cost.
c) Trim Kits are available in several sizes and include Gloves, Glove Flanges and Gaskets, Tempered Glass Lens, Inner and Outer Lens Protector, Lens Frame with Gaskets and Screws. A Floodlight Assembly is included which includes a Duplex Outlet and Power Cord.
d) Cabinet Plans are included with all of the above kits, but are available separately at moderate cost and can be shipped via 1st class mail to U.S. and Canada.

Dust Collectors & Vacs
To remove the dust created in cabinet blasting, Skat Blast has a choice of Vacuums for smaller cabinets and Dust Collectors for the larger cabinets. All run on 115 volts for easy hookup to your existing power supply. An accessory "Final Filter Outlet Kit" is available at extra cost that connects to the outlet side of the Vacuum or Dust Collector. With this kit, you can prevent dust from escaping into the room in case of vacuum bag failure. You can also determine if your vacuum is leaking by checking the inside surface of this bag. If buildup is more than just a light coating of dust, inner Vacuum or Dust Collector bag(s) need replaced. Final Filter Outlet Kit provides a cleaner and quieter shop environment and is described in a Free Catalog offered by TP Tools in Canfield, Ohio. To receive a Free Catalog, go to www.tptools.com and click on the Free Catalog Icon. A 164 page descriptive catalog will be mailed to you the same or next day via 1st class mail.
Which do I need - Vacuum or Dust Collector?
A. Our Vac-35 (shown below left) is recommended for light-duty use. This vacuum is included with most of our smaller for those who plan on using their cabinet a few hours a week, and is specifically designed for removal of the dust created in blasting. As you blast, the dust is pulled into the vacuum. Vac-35 has a vacuum bag made of space-age material with a rubberized coating called "soil release" fabric.
This bag has weights installed to assist in the cleaning process. During operation, the bag is pulled up towards the vacuum motor at top of the canisters. Clean air exits out the top opening of the vacuum and dust is confined to the inside the vacuum bag. Each time you shut off the vacuum, the weights allow the vacuum bag to drop to the bottom container and most of the dust falls off the inside rubberized coating of the vacuum bag. In the process, the bag surface is cleaned automatically.
For further cleaning, we recommend that (with vacuum turned off) you lift the vacuum and slightly tap it on the floor, to further dislodge any remaining dust. It is not necessary to disassemble the vacuum until the bottom container is about 1/3 full. You will be able to tell this, as gradually the vacuum will feel heavier each time you pick it up to tap on the floor. At this time, vacuum bag should be disassembled and the excess dust discarded. Handle the rubberized coating of the vacuum bag carefully, as the surface can be easily damaged. Replacement bags are always in stock for replacement purposed.
A. Vac-36 (shown right below) is similar in appearance to the Vac-35, but instead of a vacuum bag, has a HEPA cartridge filter to collect the dust created in blasting. This cartridge also has a "soil release" coating so that dust will drop off when cabinet is shut off or taped on the floor. After bottom container is about 1/3 full, it should be opened and excess dust discarded. A HEPA filter provides a finer filtering of the dust, and is required for certain applications where EPA regulations are in force. Coming soon is our New Vac-37 (will have a larger HEPA Filter).
B. New Vac-40 and Vac-45 (HEPA) are now available and replace the vacuums shown above. For information, specifications and pricing, see www.tptools.com.
C. Dust Collector (Shown to left of cabinet in picture below): If using your Cabinet more than 1 or 2 hours daily, or for any type of commercial or industrial use, we recommend that you upgrade your cabinet to a Dust Collector. Dust Collectors have a larger 5" inlet hose to handle more volume of dust and motor is a commercial grade type that is not exposed to the dust, as it is above the filtering area below. Inside the dust collector are tubular bags with "soil release" fabric, so that the dust can drop into the bottom of the unit. Our Dust Collectors have a spring-loaded "shaker assembly" on the side to manually dislodge the dust from inside the dust collector bags. The dust falls into a convenient bottom clean-out drawer for easy disposal. Dust Collectors are not shown below in detail, but can be seen at www.tptools.com. Feel free to call TP Tools Toll Free at 800-321-9260 for more information on the advantages of our Dust Collector Systems, or for a Free TP Tools Catalog. (Phones are answered live - no buttons to push and no waiting).
Vac-35 is shown left & Vac-36 (with HEPA filter) is shown right. (Final Filter is optional).
