The Vision Satellite Trench Foam Sanitizer is an automated, "adjustable flow" foam applicator for feeding "custom made" foam bars. This venturi foamer uses city water pressure (40 - 125 PSI) to draw and blend chemical concentrate into the water stream and create a wide range of dilution ratios. Rich, clinging foam is created by injecting compressed air into the solution to greatly expand volume and coverage ability. The water, chemical and air flow can be adjusted "on-the-fly". Vision Satellite units are activated by compressed air from a Vision Satellite Controller and operated by compressed air local to the satellite - No electrical connection is required at the satellite location. The Vision Controller features highly flexible programmable settings with multiple options to precisely manage trench foam sanitizing in one or more zones.
