Oil mist — small airborne droplets of oil — is one of several pollutants that cannot be extracted by standard ventilation. It’s caused by high-speed rotating parts, coolant under pressure impacting with surfaces, flushing nozzles, heat generated by machining, and lubricant spray or misting systems. There are many benefits to controlling oil mist, including health and safety, costs savings and increased productivity. Though the human body offers some self-defence, extraction at the source is required.
One method of extraction is an oil mist collector, like Filtermist. Here’s how it works:
- The three-phase motor rotates the drum at high RPM, creating a vacuum and drawing the oil mist into the unit.
- The oil mist particles collide with the vanes of the rotating drum and coalesce into larger droplet-sized particles.
- These larger droplets are forced through the perforations in the drum and by centrifugal force and impact on the inside of the outer casing.
- The droplets are then forced up the inside wall of the casing to the return spigot where they are returned to the machine.
- Clean air is exhausted through the top of the unit back into the shop.
- A dry smoke afterfilter can be fit over top of the motor as an option for applications that require it.
Filtermist Xcel features many enhancements, including: compact construction to reduce size and weight; curved vanes to improve airflow and collection efficiency; new entry cone to optimize air distribution; reduced drum/case gap to minimize droplet fragmentation and improve filtration efficiency; and split casing to allow easy access for maintenance.
AMT Machine Tools, based in Etobicoke, Ont., offers an extensive inventory of Filtermist oil mist collectors.
