Manhole Ventilation Passthru (MVP)
Allegro's Manhole Ventilation Passthru is the first system that combines the low profile manhole air vent, 90° elbow and built in mounting all in one unit.
The MVP comes with a collapsible vinyl duct that is stored in a small storage bag that can be dropped down into the manhole with a quick release of the drawstring. The manhole cover fits into a flat channel corner for stabilization.
Made from Linear Low Density Polyethylene, the MVP is compact, lightweight and recyclable. Unit is easy to store and ships in one small carton. Available for 8" and 12" ducting.
