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.

Negative Pressure Duct - 24" (Diameter) * 16 ft (Length) The 24” in diameter negative pressure proof duct has a length of 16 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.
