Allegro Manhole Ventilation Passthru

Introducing the new Allegro Manhole Passthru entry system. This unit is combined in an all in one unit making ventilation of the manhole entry simple. It has a duct bag built directly into it so all you have to do is fold up and tighten the draw strings. When the Manhole Passthru is needed again just undo the draw string and drop it down the confined space manhole.

Allegro has made this system with the ducting being a combination of vinyl and polyester with a PVC coating. The PVC coating is a heat resistant up to 180 degrees F. The 90 degree elbow and lip of the unit is made out of a Linear Low Density Polyethylene.

The Allegro Manhole Passthru is lightweight weighing in at only 14 lbs and shipped in a compact box making shipping also cost effective.

This unit can be used with any of the Allegro blowers found on this page
