EURAMCOSAFETY UB20xx M.E.D.™ Manhole Entry Device

  • The Intrinsically Safe UB20xx System utilizes high strength polymers with an anti-static housing designed to discharge static buildup safely. The M.E.D.™ allows workers to enter and exit small man-size openings while maintaining continuous 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 the new swiveling elbow makes duct alignment easy.
  • 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 rugged polyethylene construction endures heavy, negligent use and will last for years. 
  • Comprised of three components, the M.E.D.™, swiveling elbow, and universal mount, the RAMFAN M.E.D.™ system increases safety by maintaining continuous airflow.
  • Ventilate without blocking entry
  • Maintain airflow while working
  • UB-line compatible
  • Anti-static housing
