vent® offer Easy Cleaning Solution for in the Duct & Ventilation Systems

vent® works with Enzymes that Continuously Clean even the Strong Contaminated Ventilation System in Industrial or Commercial Kitchen / Lab / Food Processing Industries

Biochemical Reduction Nebulized into the Exhaust Duct.

The Liquid Mist is Distributed inside the Exhaust Duct just like the Greasy Particles in the Exhaust Air and Split the Greases up in Glycerine and Fatty Acids. This will Soften all the Dirt, Grease, Oil, etc

Solvation of the Grease will Dissolve them from the Duct Walls
Those Soften Residues will Flow into the Grease Collection Channels. Grease drain Cocks Facilitate Draining in Longer Duct Sections.

Encapsulation will "Trap the Odours
The Odour Absorber will Absorb Unpleasant, Rancid Odours thus stop Attracting Pest or Mice into the Ventilation System
