Made in the USA, Cellofoam North America’s PERMAFLOAT® rotationally molded Lift Tanks can be used to gain “freeboard” (height above the water) on existing docks, temporarily lift dock sections for repairs and/or replacement of flotation, and also to eliminate twisting and listing to stabilize the dock. Also suitable for use in boat lift construction. PERMAFLOAT® Marine Lift Tanks are large Heavy Wall air tanks that can be filled with water to submerge them and then re-floated by evacuating the water with air pressure. Our Marine Lift Tanks are a hollow one piece rotationally molded part manufactured from durable virgin linear low density polyethylene black material with ultraviolet inhibitors, available in both .300” nominal wall thickness and .375” heavy wall thickness. This material meets Industry Standards, offering a balance of toughness, rigidity and environmental stress crack resistance as well as low temperature impact performance. Quick Facts • Resistant to damage from the sun, salt water, fresh water, debris, oil, gas and marine organisms, making them virtually maintenance free. • Uniform, consistent thickness throughout tank. • Molded-in integral slots for easy and durable mounting. • Tanks include 1” pre-inserted pipe-thread hose fitting. • 100% tank tested for integrity. • Destructive puncture and thickness testing performed for each production run.
