What is a Cage Venturi Tube?
A Cage Venturi Tube is an essential component of dust collector systems designed to enhance the cleaning efficiency and airflow distribution in baghouse filters. Installed on the top of the filter bag cage that is the Venturi tube acts as an accelerator that increases the pulse jet air pressure including ensuring the effective dislodging of dust from the filter surfaces.
Hebei OuTai Environmental Protection Equipment Co., Ltd. manufactures high-quality Cage Venturi Tubes that is engineered for optimal performance and extended service life in industrial dust control systems.

Why Our Cage Venturi Tube is Unique Compared to Other Bag Cage Components
The Cage Venturi Tube plays a unique role by controlling airflow velocity and pressure during cleaning, ensuring every part of the filter bag receives uniform air impact.
This makes it more effective than standard open-top cage designs, as it:
· Improves cleaning intensity without increasing air consumption.
· Reduces pressure loss across the filter media.
· Prevents dust re-deposition on cleaned bags.
· Increases the lifespan of both bags and cages.
Why It’s Important to Have a Cage Venturi Tube in Your Industry
A Cage Venturi Tube is vital for any dust collection or air filtration system because it optimizes dust removal efficiency and reduces operational expenses. Without a Venturi tube:
In industries requiring clean and consistent airflow, Cage Venturi Tubes are not optional—they are essential.
