Description

Plug Technologies’ Flat-Max™ plate style vacuum testing heads are used in conjunction with the Max-Vac™ Venturi Pump II to evacuate the air from a manhole while performing a manhole vacuum test. The 38” Flat-Max™ weighs only 45 pounds and has two lifting handles allowing one person to perform a vacuum test.  Both the 555-38 (38” OD)  and 555-44 (44” OD) Flat-Max include the new Cam-Lock® connection between the Flat-Max and the Max-Vac II Venturi pump.  The Cam-Lock® fittings allow for a secure and stable connection between the Max-Vac™ II and the Flat-Max™ allowing for maximum vacuum.
