General Description

Negative Pressure Duct - 20" (Diameter) * 32 ft (Length)


The 20” in diameter negative pressure proof duct has a length of 32 feet and is made out of a PVC material. It can endure negative pressure of 8000pa.

Function
The duct connects creates suction and exhaust through helix wire-framed ducting. One end of the duct can be connected to a portable ventilator via straps and ducts can be attached to one another, interconnecting them into a ducting system, using the same strapping. The PVC fabric of the duct is fire-retardant and the duct has a lightweight build.

Applications
The air duct is used in a ducting or HVAC system with a ventilator anywhere there is narrow space and poor air supply, especially in environments where ship welding and coating occur. It can be used for duct cleaning, heating and cooling.
