It is not easy to build an indoor shooting range. You need to plan the design based on the number of shooters and the type of ammunition. You need ballistic protection to prevent injuries and sound-proof mechanism to muffle the crackling sound of firing. You also need a perfect bullet trap based on your necessities. The installation of an indoor shooting range ventilation system is more important than the features mentioned above.
The air inside the indoor shooting range becomes quickly polluted due to the release of lead and carbon-monoxide after the firing. You cannot expect a normal HVAC system to properly evacuate the polluted air. You need a customized HVAC system with specialized features in order to keep the air fresh and free of any pollutant. You need to remember some essential factors during the installation of a ventilation system for your indoor shooting range.
Air-Flow Measurement
The 75 feet/minute airflow is considered optimum within the firing lines of your indoor shooting range. The airflow does not drop below 50 feet/minute at an individual point with this particular level of flow. The friction of lead slug against the gun’s barrel creates airborne lead residue. The 75 feet/minute airflow is necessary to ventilate the lead-filled air from the shooters’ respiratory zones within the firing lines. Hence, it is necessary to maintain the optimum airflow level during the building of an indoor shooting range ventilation system.
Negative Pressure
It is not enough to remove the lead or carbon-monoxide contaminants from the shooting lines. The spaces outside the firing line, though, within the indoor shooting range may also become polluted. The indoor shooting range ventilation system needs to keep these areas free of contamination. The special HVAC systems for indoor shooting ranges need to create negative pressures in order to perform this task effortlessly. The negative air-pressure will prevent the ingestion of harmful particles in any enclosed area of your shooting range.
The majority of indoor shooting range ventilation systems create laminar air-flow. It supplies fresh air from behind the shooter and drive it toward the target area. This type of airflow may create a vortex and allow the contaminated air to enter the shooter’s breathing zone. Hence, the shooting range HVAC systems need to maintain 10% higher exhaust than supply. The negative air-pressure can remove the largest lead particles and lead dust with equal efficiency. It prevents cross-contamination within the entire indoor shooting range.
Usability
You need specialists not only for the installation or maintenance of an indoor shooting range ventilation system. You also need trained technicians to control the advance features of these systems. It is not always possible to find skilled technicians. The user-friendly features of an indoor shooting range system will help you properly control the unit. It is necessary to evaluate the control and safety mechanism of indoor HVAC unit during its installation. Visit Here: Rushing Air Treated Air Systems
