This negative pressure duct is designed specifically for negative pressure exhaust systems. Its built-in, sturdy metal spiral supports prevent the duct from being crushed by negative pressure during high-pressure extraction, maintaining maximum ventilation efficiency. The smooth duct wall provides low airflow resistance, effectively extracting dust, smoke, and hazardous gases after blasting. The high-strength PVC coating provides excellent resistance to negative pressure and abrasion, making it ideal for use with dust removal fans to improve visibility and air quality at the work surface.

Use high quality raw materials to ensure product quality;
Being engaged in the field of ventilation system for more than 40 years, have rich experience in ventilation design;
Cooperate with several research institutes and have the latest technology;
Several automatic ducting welding production lines with a monthly output of 20,000 flexible ventilation tubes with assured batch order lead time;
PVC ventilation tubes are available in custom sizes to ensure a perfect fit for your requests;
The spiral ventilation duct is coupled with zipper and Velcro. The extra fabric on which the zipper/Velcro is sewed is welded to the flexible duct body to ensure that there are no sewing needle eyes throughout the ducting, reducing air leakage.
