The MistBuster® 500 by Air Quality Engineering is a compact, high-efficiency electronic air cleaner designed to remove oil mist, coolant mist, smoke, and other airborne particulate produced by CNC machining and metalworking processes.
With an airflow capacity of 500 CFM, the MistBuster® 500 delivers powerful source capture in a machine-mounted package, making it an ideal choice for small CNC machines or installations where space is limited.
Its multi-stage filtration system, featuring electrostatic precipitation technology, effectively captures submicron particles, helping shops meet OSHA and NIOSH indoor air quality standards. The washable collector cells reduce consumable filter costs and minimize downtime, while the quiet operation improves overall workplace comfort.
The MistBuster® 500 offers multiple mounting configurations—including direct machine mount and ducted connection—to fit diverse shop layouts. It’s designed for continuous operation in demanding industrial environments, providing clean air, reduced maintenance, and long-term value.
