Timed Drain Maintainer Foam Sanitizing System

Model # 976810

The Timed Drain Maintainer Foam Sanitizing System is a low volume foam applicator for creating a constant, microbial foam barrier between "ready-to-eat" areas and effluent in the drains. This venturi injection system uses city water pressure (50 - 125 PSI) to draw and blend chemical concentrate into the water stream and create an accurately diluted solution using precision metering tips. The adjustable timer runs for up to 1 minute and delays for up to 1 hour. When the system activates, compressed air is injected into the solution to create rich, clinging foam which is projected through a user-supplied discharge hose directly into the drain.

Key Features
  • Projects bursts of rich, clinging foam into drains at set intervals
  • Creates a microbial foam barrier between sanitary areas and drain effluent
  • Foam increases chemical contact time and effectiveness
  • Adjustable timer projects foam for up to 1 minute and remains off for up to 1 hour
  • Adjustable foam consistency (wet/dry)
  • Ideal for sanitizing drains or preventing grease build-up
  • Chemical-resistant components ensure durability and years of trouble-free performance
  • See Catalog 9 for other chemical management systems
