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.

Is the hose water proof?

It is waterproof in the sense that rain will not penetrate it since it is pvc coated, however submerging the hose might not be as effective.
