Dust Collection Technology on the Range

Action Target has worked closely with Carey’s Heating and Cooling to provide industry-leading ventilation systems that improve the safety of ranges around the country. However, it is sometimes unclear as to why ventilation systems are needed in the first place. For this reason, this week’s Action Target Journal explains why such systems are essential in today’s ranges.

Every time a bullet impacts the plate in a steel bullet trap, there is a small amount of dust (bullet fragments) that is generated from the collision. However, with dust collection technology, as the bullet enters into the chamber of the bullet trap it takes in air with it. Because the chamber is a sealed environment, taking in this air creates an element within the high-pressure chamber. A dust collection system is required because of the air that is brought into the chamber. One of the technologies Action Target has developed to optimize dust collection is called Negative Pressure Technology. To better understand this concept, let’s look at an example.

Imagine a person holding a glass in their hand as if they were going to take a drink from it. Then, imagine the person placing a cotton ball on the closest part of the rim of the glass. It would be impossible for them to blow the cotton ball to the other side and have it land on the opposite edge.

Action Target's Total Containment Bulle TrapThis is the same concept that is taking place when a bullet travels into the bullet trap. In front of the bullet there is a large wall of air that is being pushed into the trap. When a supersonic crack sounds, what is actually happening is that the bullet is breaking the shockwaves of air. This same air is what is being pushed in the bullet trap. If there were no dust collector on the bullet trap, the overpressure of the air entering the trap would collect surrounding particles and lead dust and shoot it back onto the range. This is where the dust collector becomes essential. The dust collector enables a negative pressure to be established inside the bullet trap, and it functions at a rate that is high enough to overcome the bullets and air pressure entering the trap. Referring again to the example of the cotton ball and the glass, if there was no back on the glass it would be easy to push the cotton ball to the rear of the glass by blowing on it. This is possible because there is no overpressure in the glass.

Although many other systems have attempted to use Action Target’s patented negative pressure technology, none have succeeded. Action Target continues to hold the patents on the negative pressure systems utilized in many bullet trap chambers and this system continues to provide a pressure and cleaning method that allows the minute particles of lead to be picked up and safely gathered together for recycling.
