Durag Group D-FW 410 Dust Filter Leak Detector

The DURAG D-FW 410 is a dust filter leak detector designed for the continuous, real-time monitoring of solid particles in a gas flow. Using the triboelectric principle, the D-FW 410 helps identify filter leaks early so operators can respond quickly to dust level changes, reduce product loss, and maintain more stable filtration performance. DURAG positions the unit as a cost-effective, low-maintenance solution for ongoing dust trend monitoring and filter leak detection in industrial applications.

Because the D-FW 410 measures directly in the duct, it does not require sample handling. This simplifies installation and reduces maintenance while supporting fast response to process changes. DURAG also highlights the detector’s low drift, long-term trend monitoring capability, and IP66 construction for harsh environments, making it well-suited for facilities that need dependable filter leak detection without unnecessary system complexity.

Available in Canada through Westech Industrial, the D-FW 410 fits well within Westech’s emissions and dust monitoring offering for customers looking to improve filtration performance, detect early baghouse or filter issues, and support environmental compliance.

PRODUCT FAQ's

What is the DURAG D-FW 410 used for?
The DURAG D-FW 410 is used for real-time filter leak detection and continuous monitoring of dust trends in gas flow. It is designed to help operators identify filter wear, failure, or process disruptions before they lead to larger emissions or product loss.
How does the D-FW 410 detect dust?
The D-FW 410 uses the triboelectric principle to detect solid particles directly in the gas stream. This in-duct measurement approach eliminates the need for sample handling and supports fast feedback on dust level changes.
What types of applications is the D-FW 410 suited for?
DURAG lists applications including filter leak detection, dust arrestment plant management, and process control and trend monitoring in systems such as baghouses, cyclones, and exhaust ducts. It is also described as suitable for industries such as cement, metalworking, food processing, and chemical manufacturing.
What makes the D-FW 410 a low-maintenance option?
Yes. Westech Industrial can help customers in Canada evaluate where a dust filter leak detector fits within their filtration, emissions, or process monitoring strategy and support selection of the right monitoring solution for the application.
Can Westech help identify where the D-FW 410 fits in a dust monitoring program?
Yes. Westech Industrial can help customers in Canada evaluate where a dust filter leak detector fits within their filtration, emissions, or process monitoring strategy and support selection of the right monitoring solution for the application.
