Merrill - Plastic Floats

An Air Volume Control System with over fifty years of service.  Proven performance by independent testing laboratory.  Only Merrill Manufacturing™ has a foldable float with balanced buoyancy and can be inserted into a pressure tank through the pipe connection hole.

A Merrill-Float is a barrier to absorption of air by water under pressure.  Merrill-Float assures a smooth working water system by separating the volume of air from the water within the pressure tank.  Merrill-Float is made of a durable plastic approved by U.S. Food and Drug Administration, for the interior of containers carrying liquids for human consumption.  Only Merrill-Float will stay level on top of water to separate air from water in tank.

1) Simple Economical Way to Minimize Water-Logging of Pressure Tanks.

Benefit - Most economical long life air volume control for tanks.

2) Plastic Flotation Ring forms a seal between water and air inside pressure tanks.  The air-water seal is assured by Merrill Manufacutring™ exclusive "Wiper Blade."

Benefit - Effective water/air volume separation in the tank.

3) Eliminates Other Air Volume Controls or the need for air-charge, bleeder valves or air-release valves and headaches caused by corrosion of these parts.

Benefit - Merrill-Float will not corrode and is not effected by chlorine.

4) Float`s Balanced Buoyancy is assured by a sealed, crush-proof flotation ring within the float, even if the tank drains.  Merrill-Float resumes its floating position when water returns.

Benefit - Balanced buoyancy insures float will maintain flat horizontal position on top of water.

5) Merrill-Float is Built for Permanent Service, yet this water-log barrier can be inserted into place in minutes.  The 12" through 20" sizes are flexible enough for insertion through a 1-1/4" tank opening.  The 24" size will require a 1-1/2" opening.  The 30" and 36" size require a 2" tank opening.  Merrill-Float recovers its stable circular shape and assumes its proper position after insertion in tank.

Benefit - Can be inserted in existing or new tanks.
