207HC Level Master™ with SS Bracket

Model # 989207

The 207HC Level Master™  with Stainless Steel Bracket is a water driven chemical proportioner that clamps to the rim of a user-supplied tank and automatically maintains a constant supply of highly concentrated ready-to-use solution. When the solution in the container drops below a pre-set level, this venturi injection system uses city water pressure (40 - 80 PSI) to draw and blend a high concentration of chemical into the water stream to create up to 1:1 dilution ratios. The solution replenishes with a water flow rate of 2.0 GPM @ 40 PSI and will cycle continuously.

Key Features
  • Automatically maintains a pre-set level of ready-to-use chemical solution
  • Achieves strong dilution ratios, up to 1:1 (with water thin chemicals)
  • Weaker ratios controlled by precision metering tips & plugs
  • Refills with a water flow rate of 2 GPM @ 40 PSI
  • Unsinkable solid polypropylene float suspended by a rigid "push rod" ensures smooth operation and prevents the float valve from sticking in the open position
  • All stainless steel mounting bracket attaches to open tanks
  • Chemical resistant wetted components ensure years of outstanding performance with minimal maintenance
  • Industrial-strength design holds up in tough environments
  • Available with paired tanks (#989225)
