Air-Loc® Pressure Testing Systems

Used to perform a low-pressure air test from manhole to manhole. This is done by installing two Cherne Air-Loc plugs and using Cherne's Air-Loc Panel to inflate the plugs and pressurize the pipeline. The test pressure is monitored for a predetermined amount of time for any decrease in pressure. If pressure drops less than 1PSI, the test passes. If a leak is detected, additional equipment is required to isolate the leak.

If the line acceptance test indicates a leak in the sewer line, it becomes necessary to locate the leak(s) so that proper repairs can be made. The Leak Location Kit provides everything needed to perform a leak location (segment) test except for plugs and an air source.

A leak location (segment) test is accomplished by first stringing the sewer line using a Chenrne Air-Loc Line Stringer or float line. Once strung, a winch cable is used to pull two Air-Loc Leak locator plugs, which are attached together with an interconnect hose, through the pipeline in 22' intervals. Air is introduced between the plugs at each 22' increment until the test fails. Then by moving the plugs back and forth the leaks can be isolated within two feet.

The Versatile Air-Loc Fan Assembly can be used as a line stringer, smoke blower and ventilator.
Made from lightweight cast aluminium, this assembly includes a 5HP Honda or Briggs & Stratton engine and top mounted handles for easy manoeuvrability.

Line Stringer - will string a 300 foot section of sewer line in less than one minute without plugging the line. The vacume created by the kine stringer pulls a lightweight nylon parachute through a wet or dry line.

Ventilator - supports OSHA guidelines for confined space entry. Cherne Ventilators provide up to 2,350CFM as a blow-in ventilator and up to 3470 CFM1 as a suction ventilator. Cherne's suction ventilator outperformed similar competitive models by 40% 2 at 3" of static pressure.
