Patented ~ The Man Pan Classic is structurally designed to prevent bending or buckling under load. The patented convex positive arch center provides unusually rigid construction and less volume for collected water and silt, which helps to prevent The Man Pan Classic from falling into a sanitary manhole system and causing maintenance problems.

Lifting Lugs

Patented ~ Patented lifting lugs are embedded into The Man Pan Classic. Field staff can remove The Man Pan Classic with the same J-hook or pick that they use to remove the manhole cover without broken straps or strained backs. Or—because it is not necessary to reach into the collected muck to find the strap—without the temptation to drain the water and debris by punching a hole in the insert!

High-Quality Gasket

The Man Pan Classic comes with a high-quality elastomeric seal. This gasket attached under the flange is what ultimately prevents unwanted inflow.


The Man Pan Classic standard construction is 100% Recycled High-Density Polyethylene (HPDE) plastic, but it is available in other non-corrosive materials to meet specific needs.

Degassing Valve (Optional)

If a section of the system requires it, an optional one-way degassing pinch valve can be installed.The flexible elastomer construction will not clog and is durable.

These valves are for degassing only.  Man Pan models do not use drain valves that can misfunction and allow surface inflow without systems operations’ knowledge.  Man Pan models are also available with drilled weep holes if some drainage is needed.
