The Timed Entryway HV Foam Sanitizer (24V) is an automated foam applicator for projecting sanitizing chemicals on to floors of 8' - 16' wide overhead doors to prevent cross contamination. When activated, this venturi injection system uses city water pressure (35 - 125 PSI) to draw and blend chemical concentrate into the water stream to create an accurately diluted solution. A high volume of rich, clinging foam is created by injecting compressed air into the solution to greatly increase volume and coverage ability. The foam is then projected through the discharge hose and unique Spreader™ nozzles. The system timer is user-programmable to meet the needs of any facility. This unit requires 24VAC electrical input - a locally sourced standard step-down transformer is required.
