The Venturi effect refers to the pressure drop that occurs when a fluid or air flows through the narrow section of a filter bag. Venturi tubes are widely used in dust collector frames and filter elements, utilizing their suction effect to transport dust particles. Located at the top of the filter cage, their working principle is based on fluid dynamics. During a cleaning pulse, high-pressure air flows rapidly through its narrow throat, creating a vacuum and drawing a large amount of surrounding air into the filter bag.
Our Venturi tubes are available in aluminum and stainless steel, and in styles including one-piece, traditional, and louvered designs.

Maximizing Pulse-Jet Baghouse Performance
As a manufacturer of filter cages, Filmedia understand that a high-performance cage requires an optimally designed Venturi.
- Precision Engineering: Each Venturi is meticulously machined to ensure optimal aerodynamic performance for a strong, consistent pulse.
- Seamless Integration: Our Venturi are designed to perfectly fit our filter cages, creating a unified system that performs flawlessly.
- Durability: Robust construction prevents deformation under high-pressure pulses, ensuring long-term reliability.
- Expert Guidance: Our technical team can help you select the perfect material and design for your specific dust collection challenge.
We have 5 materials of Venturi tube can be chosen and differents types.
Stainless steel venturi tube
It is generally made of 1.2mm thick stainless steel plate through stretching and forming. Its characteristics include a smooth and beautiful appearance, stable and reliable quality, and effective extension of the service life of the filter bag.
- Exceptional Durability: Outstanding resistance to corrosion, moisture, and high temperatures.
- Extended Service Life: Performs reliably in harsh chemical and abrasive environments.
- Consistent Structural Integrity: Maintains strength and stability under demanding operating conditions.
