Allegro Blower Accessories

Made of durable vinyl polyester in 8", 12" or 16" diameters and designed for rugged use. The standard yellow ducting is constructed with vulcanized external strips, steel reinforced wire hoop, and cuffed with an attachment belt. The black colored ducting is the statically conductive material safe for use with explosion proof blowers. 

Manhole Ventilation Passthru - Replaces the Saddle Vent

Allegro's MVP is the first manhole system to combine the low profile manhole air vent, a 90 degree elbow and built-in mounting all in one unit.  This unit comes with a collapsible duct, for easy entry, stored in a small storage bag which can be dropped down into the manhole with a quick release of the drawstring.  The collapsible duct springs back into shape once a worker is down into the manhole.  The ducting is vinyl and polyester with a PVC coating and is heat resistant up to 180 degrees F.  The manhole cover fits into a flat channel corner for stabilization.  Compact, lightweight and made from Linear Low Density Polyethylene (LLDPE), this unit is easy to store and ships in one small carton.  Recyclable.

Allows safe connection of additional ducting for remote locations, this connector is constructed of galvanized steel with a raised lip to hold ducting in place.
