The Mark III Continuous Air Inverter from CIPP Services can install 6- to 18-inch liners using compressed air and a steam-air mixture for curing with interchangeable adapters. The unit has the ability to maintain constant air pressure within the liner from the start of the installation to the final cure cooldown. The insertion gland on the unit can be sealed off to allow full steam-air pressure for curing, eliminating the need to deflate the liner to install a steam cap. It has adjustable legs and allows for the unit to swivel 180 degrees for horizontal installations. 815/712-8708; www.cipp-services.com.
