Donaldson Torit Mini-Mist Collectors

The Donaldson Torit Mini-Mist is designed for CNC machining, grinding, turning, milling and drilling operations. It is used to collect coolant mists such as oil, water-soluble and synthetic coolant mists. The Mini-Mist design is compact and available in two models; MM 500 for light-duty operations and MM 1200 for machines requiring higher airflow or applications that require a mist and smoke collector.

What size are mist droplets/particles?

Mist can generally be defined as a liquid droplet 20 microns in diameter or smaller. Oil-based fluids typically produce mist droplets that range from 0.5 microns to 10 microns. A smoke droplet is typically smaller, from 0.07 microns to 1 micron, and is a solid or liquid aerosol.

What determines the performance of a mist collector?

A mist collector can be characterized by pressure drop, efficiency, and flow rate. Pressure drops affects the energy required to pull the airflow through the system. The efficiency of the system determines how clean the air will be as it leaves the collector and flow rate determines how much air will be cleaned.
