Air-Loc® Manhole Testers

The Air-Loc Vacuum Generator allows vacuum testing of a manhole without the use of a separate
vacuum pump. This device turns your standard air compressor into a vacuum source for testing manholes.
Simply attach the unit to a head assembly and an air compressor to draw a vacuum in minutes.
The vacuum generator 450 produces 14 CFM at 10" HG and the NEW Vacuum Generator 600 produces 42 CFM at 10" HG.
Air-Loc Manhole Testers conform to ASTM Specification C1244 Standard Test for Concrete Sewer
Manholes by the Negative Air Pressure (Vacuum) Test and ASTM C1227 Standard Test for Pre-cast
Concrete Septic Tanks.
