Bladder-style head assembly for Cherne Air-Loc manhole vacuum testers, illustrating sealing mechanisms at frame and cone top, highlighting efficient manhole testing features.

Cherne Air-Loc Bladder Style Manhole VacuumTesters  

Air-Loc® Manhole Vacuum Testers provide the most efficient, accurate and cost-effective method of testing new, existing and rehabilitated manholes, per ASTM C 1244. Vacuum testing identifies infiltration and exfiltration problems by creating a vacuum in a manhole and then monitoring a gauge for vacuum loss. Less expensive and faster than water testing, the Air-Loc® manhole tester’s remote-inflation and monitoring system keeps users away from the “danger zone.”
