Flexible duct connects to compatible negative air machines for air cleaning applications. The duct can be connected to a negative air machine's intake manifold to pull contaminated air into the machine so it can be filtered. The duct can also be connected to a negative air machine's exhaust ring to discharge clean air from the machine into a room or outdoors.

Duct clamps secure flexible ducting onto the intake or exhaust outlets of a compatible negative air machine.

Intake manifolds (also known as inlet manifolds) connect flexible duct to a compatible negative air machine to pull contaminated air into the machine so it can be filtered. This allows the negative air machine to be set up outside of the area that is being treated, which helps free up space inside the treatment area.

External exhaust kits contain parts that install onto negative air machines to move filtered air from the machine to the outdoors or another area outside of the area being treated. They create negative pressure in the area being treated and are used in applications where the machine will sit inside the treatment area.

These parts are used to replace worn, lost, or damaged parts on negative air machines so they can continue to operate effectively.
