The dust left in an indoor fire range at the end of the day is a serious concern from both a health and safety standpoint. The accumulation of lead particulate presents a challenge from the health side and presents a regulatory concern as well. That is why we recommend the PRO Series with the Integrated Floor Sweep for firing ranges. The Integrated Floor Sweep makes cleaning up the lead and powder residue quick and easy. For an extra layer of protection use the 550H which features our Dual-Stage HEPA Filtration. With two sets of HEPA filters one on the intake side and another on the exhaust side providing the best HEPA level filtration available.
