Coolant Mist Collector Combines Centrifugal Separation with HEPA Filtration

Edge Technologies will exhibit the Vortex AF water-solubale coolant mist collection system designed for machine tools performing wet machining operations. The Vortex AF is described as a synthesis of advanced centrifugal separation and HEPA air filtration, achieving high-efficiency air purification with minimum maintenance and low cost. The Vortex is designed with multi-layer filtration to thoroughly capture fine particles with an interception capability of over 2 microns.

The Vortex features a three-stage separation-filtration process. At the first stage, the coolant mist airstream collides with the fish-scale profile, coalescing the mist into larger droplets. Then, through a wind shear effect with the 70-degree, self-draining mesh filter, additional smoke and particles larger than 2 microns are captured. The multi-layer stainless steel mesh filtration element with built-in handle is cleanable for reuse. At the third stage, an E12 HEPA after-filter finishes the air purification to a 99.97 percent filtering efficiency by capturing all particles larger than 0.3 microns before releasing the purified air back into the plant. The Vortex also recycles collected coolant back into the machine. 

The 220-V, three-phase design consumes low power and is available with the choice of an independent power supply. The Vortex AF can be mounted on the machine, on a stand or on the ceiling. 

The air flow capacities for the AF line range from 475 to 1,700 cubic feet per min., with units designed for working envelopes ranging from under 215 to 1,130 cubic feet.
