The Timed Trench Foam Sanitizer is an automated system for creating rich, thick foam sanitizer at regular, timed intervals, and feeding it to a foam bar located in the trench drain that needs to be sanitized. This venturi foamer uses city water pressure (35 - 125 PSI) to draw and blend chemical concentrate into the water stream and creates 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 system timer is user-programmable to meet the needs of any facility. Custom foam bars (sold separately) accommodate trench drains from 10' to 48' in length.
