A blast pot is a container used to hold abrasive media for blasting operations. They range in size from 80 to 300 pounds and can be made of plastic or steel. They are cost-effective and efficient for removing corrosion and finishes from metal surfaces, as well as wood, masonry, and glass. Blast pots are easy to install and can be used by anyone from DIY enthusiasts to large factory owners. They are filled from the top and use a gravity feed system to deliver abrasive into the compressed air line.
A blast pot is a specially designed container used to hold loose abrasive media used in blasting operations. Most are designed to be used as an add-on unit to existing compressed air systems, allowing operators to take advantage of the many benefits of blasting without the high costs associated with installing dedicated abrasive blasting equipment. Blast pots range in size from small units with internal capacities of 80 to 100 pounds (36.3 to 45.4 kilograms) for use in light industry or home applications to heavy industry models capable of carrying 300 pounds (136 kilograms) or more. The smaller blast pot is often made from high impact plastic with larger examples usually featuring a welded steel construction. Most blast pots are open at the top of the tank for refilling and deliver the abrasive into the compressed air line at the bottom of the tank by a simple gravity feed arrangement.
Abrasive grit delivered at high velocity in a stream of compressed air is an extremely efficient and cost-effective method of removing corrosion and a wide variety of finishes such as paint and varnish from metal surfaces. Sandblasting, as it is known, can also be used to remove finishes and contaminants from wood and masonry, and can also be used to grind or etch glass. One of the easiest ways to install a sandblasting system in a home, shop, or factory where a reliable source of compressed air is available is to purchase a sandblasting pot. Consisting of little more than an open top cylinder with a compressed air fitting at the bottom, a blast pot is a convenient way to do most blasting jobs.
A wide variety of these devices are available with capabilities and construction to suit most needs, from the do-it-yourself weekend warrior to the large factory owner. The small models are usually made of strong, high-impact plastic and feature capacities of around 100 pounds (45.4 kilograms). The larger industrial varieties are usually made of plain or stainless steel and can carry 300 pounds (136 kilograms) or more of abrasive grit. The bins are usually filled from the top and gravity feed the abrasive into the compressed air line through an opening in the bottom of the tank, with some types of sandblasters having a foot switch that allows control of the flow of sand into the tank. air flow. The gravity feed system is particularly effective as it does not tend to clog even with wet grit mixtures.
