Traditionally, you would have picked from nozzle sizes that have inch designations (see list below) in their opening diameter; you still can, but also have the option of choosing a size in between these traditional opening sizes as well. This will help you fine tune based on your available air supply. For example, if a 1/4 inch (6.35mm) opening is barely too big for your air supply and you don't want to go all the way down to 3/16" (4.8mm), you can now also choose from 5 mm or 6 mm openings as well.

This may be confusing to beginners when they are choosing their grit, as they may assume that they should buy "glass bead". In fact, different abrasives are used for different purposes. Glass bead is round, like a ball. It peens, refines, cleans, and shines metal surfaces as it is used. Additionally, it removes burrs and preps the work surface for paint or other coatings. While it will remove small amounts of rust, paint, or other material, that is not its intended purpose, nor is it an effective choice. If you need to smooth out a surface, prep for paint, shine aluminum or other metals, or remove burrs...then it is a great choice. When the user needs to strip paint, rust, or otherwise remove material from an object. They should choose an angular abrasive like aluminum oxide, garnet, or similar. These abrasives are shaped with sharp edges and will slice away layers to get to the good surface. Glass bead, being round, will repeatedly pound the surface. Many commercial operations run two cabinets, the first with a stripping abrasive like aluminum oxide, and the second with glass bead. As a starting point, every cabinet deserves to have two things sitting next to it from the beginning...Aluminum Oxide and Glass Bead. Most users will be able to accomplish most of their tasks with those two products. A good starting point is white aluminum oxide 100 grit, and glass bead mil 8 (some call it 80). How to choose an abrasive: The first question to ask is whether you are working inside of a cabinet where the product can be contained and reused, or, are you out in the open where you are unable to continually reuse it? If you are in a cabinet, then you should choose a higher quality abrasive like Aluminum Oxide, for your stripping needs. While it may be more costly up front, it quickly becomes cheaper as you continually use it. If however, you are sand blasting in a garage where you are unable to recover a bulk of the product, then use something more economical. In cases where you are outside of a cabinet, but are able to recapture the abrasive on a floor, tarp, or by other means, sweep it up and reuse it. But, before you put it back into your system run it through an old window screen to remove large debris. The two most common problems with blast systems: To small of a compressor. When a system is not functioning correctly, their are typically two main culprits. The first is an undersized compressor. Typically people assume that if they are running the correct pressure, than it should work. However pressure is not the same as volume. Every individual system requires a certain volume of air, or CFM (Cubic Feet per Minute), to effectively pick up the abrasive and flow it out the other end. Once you have the volume, than you can worry about the pressure your abrasive works best at. In addition, you must match your nozzle opening size to the amount of CFM your compressor can put out (you can find charts online). In general, purchase the largest compressor you can afford, you wont regret it :-) If your stuck...To make the best of an undersized system, you may consider the following: decrease your nozzle size, take breaks while blasting to let the compressor catch up, choose light abrasives that are easy to pick up. Moisture in the system: The second most common blasting problem is moisture in the system. Every running compressor condenses the moisture that naturally occurs in the air and introduces it into your air tools, abrasive, or other operation. It is a constant battle to combat this, especially in humid environments. If you feel like the gun is "surging" in your hand, or clogging, you probably have moisture. Additionally, if your compressor is undersized, and continually runs while you are blasting without stopping, it is constantly heating up, which in turn condenses moisture at an even higher rate. Solutions to this problem include having a large enough system that it is not running all the time without a break, refrigerated air coolers or dryers (expensive), moisture removal filters (inexpensive), and various types of home made copper or metal snakes with drains, bolted to your wall (google it). Most people are not going to purchase a refrigerated air dryer, but if you are handy, you can make a "snake" of copper with at least 50 linear feet (the more the better) of pipe and bolt it to your wall right next to your compressor. As the air runs out of the compressor, it will first travel through this snake and cool rapidly as it touches the metal. A higher percentage of the moisture will then collect at the bottom of these pipes, rather then travelling on to your mainline and tool. Additionally, there are many affordable moisture removal filters on the market. About our listings: Shipping: We typically ship within one business day.
