Micro-Jet® ULV DM 7421

Includes Motor-Saver brushes for extended use applications

The Micro-Jet® ULV DM 7421 drum mounted unit features precision control of particle size, from a dry, 7-micron ULV (ultra low volume) droplet to the larger particles of conventional fogging and misting equipment.

ULV application provides greater penetration and diffusion of fog particles, allowing more concentrated solutions to be used and shortening application times. Also, the higher surface to volume ratio of small droplets makes them superior for odor control and other gas contact applications.

With precision control and variable output (0-9 oz/min), the Micro-Jet DM can handle both oil- or water-based solutions. It is easily calibrated in the field to accomodate differences in solution viscosity and density. Application sites include waste treatment plants, paper mills, parks, warehouses, and food storage centers.

Fogmaster's Micro-Jet® ULV DM 7421 -- technologically advanced fogging, with controlled flow and particle size.
