Centrifugal Mist Collectors

Donaldson Torit 290_Centrifugal_Mist CollectorCompact, direct machine-mountable mist collectors designed to collect, filter, and reclaim mist generated from machines using oil-based, synthetic, semi-synthetic, or water-soluble coolants.​

Efficient, compact design handles mist and smoke applications from 100-1000 cfm.
Three stages of filtration for high filtration efficiency and optimum filter life.
Available with high performance in-cover or in-line pre-filters for removal of swarf and large chips and in-cover impingers for applications with heavy concentrations of fine mist.
High collection efficiency of 98% on 1.0 µm increasing to 99.97% at 0.3 µm with optional fourth stage HEPA filter.
Direct-mount capability minimizes ductwork.
Recirculation of clean air eliminates the need for costly make-up air.
Provides a cleaner work environment for maximum productivity.
Helps support OSHA Clean Air Standards.

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.
