Super Vac’s “L” Ducts is a simple, yet effective solution for confined space ventilation. This durable duct features an “L” shaped design, perfect for ventilating deep into manholes and other tight areas.

Featuring reinforced vinyl, “L” Ducts can custom designed to any diameter as well as any horizontal length up to 25 ft and any vertical length up to 20 ft.
Super Vac’s “L” Duct is one piece, saving space on trucks and can quickly and easily attach to a negative pressure fan in seconds upon arrival.
