 Smoke Filters & Mist collectors For EDM Photo of MistBuster Electrostatic Air Cleaner While Electrical Discharge Machining (EDM) produces a light smoke and oil mist, it is a steady operation which should utilize some level of air filtration. The smoke and mist generated from the EDM process is generally best handled by electrostatic precipitators. Air filtration systems such as the MistBuster series of mist collectors are ideal due to their compact design, high efficiency – permanent filter systems that require very little maintenance. These compact electronic air cleaners feature variable speed airflow, low maintenance and high efficiency in a compact package that is both cost effective to purchase and due to its lack of replacement filters – cost effective to operate. Alternatively, larger central air filtration systems are available for multiple stations or for use with mixed machining operations. Consult with an air cleaning professional for assistance in sizing and selecting an appropriate commerical air cleaner for your manufacturing needs.
 Photo of MistBuster Quad Electronic Mist Collector What is EDM? EDM stands for Electrical Discharge Machining. It is a metalworking process where metal is removed through a series of rapid electrical discharges between an electrode and a workpiece under a dielectric fluid. The electrode can be fixed as in a sinker EDM or a wire continuously fed from one spool to another (wire EDM). Why do I need an air filtration system? EDM is a relatively clean process, but still generates a steady stream of mist and smoke due to their frequently long cycles. A portion of the dielectric fluid used to prevent premature arcing and to flush away the metal particles become airborne during the process and should be filtered for the safety of the employees, and to prevent soiling of the machine, parts and facility. A mist collector can also save cost by recycling the collected dielectric fluid. Request a quotation here on a mist and smoke collection system for your EDM process.
