Manhole Entry Device
The M.E.D allows workers to enter and exit small man-size openings while maintaining continues ventilation. Without such a device, duct fills the manhole opening, preventing rapid entry and exit. Tightly integrated into the UB-Line of confined space ventilation equipment, RAMFAN’s M.E.D is quick to assemble and easy to align.
Changing its cross-section from circular to elliptical and back to circular minimizes loss and optimizes airflow into a confined space, while providing adequate room for the worker to enter and exit unimpeded. The ruffed polyethylene construction endures heavy, negligent use and will last for years
