The 51000 SERIES hood is designed to create a safe work environment with a savings in operating cost without compromising containment. By operating at 60 F.P.M., air flow across the sash opening results in a 40% reduction in CFM resulting in savings in the cost of fume hood operation. The 51000 Series hood has been engineered to adhere to the standards of today's most rigorous testing procedures.

The 51100 SERIES hood is an airfoil-type hood with a 45-degree angle around the fascia and a flush mount radius airfoil across the bottom. The result is minimized turbulence with increased performance.

The superstructure is designed to remove fumes, both those heavier and lighter than air. Baffle positions are fixed for both safety and consistent and complete containment of fumes at all sash positions.

The interior of the hood is lined with a U.L.-certified Polyresin board. The exterior is fabricated of cold rolled steel and finished with acid wash and powder coat. The solid frame galvanized steel construction provides both stability and convenient knock-down ability to improve flexibility. Posts are 5" (127mm) wide.
