| 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.” Bladder-Style Air-Loc® Head Assembly Features - Seals the inside diameter of the manhole at frame or cone
- Supported by a durable aluminum brace
- Push-pin rod design for easy depth adjustment
