Durag - Model D-FW 410 -Dust Filter Leak Detector

The D-FW 410 is a highly reliable dust filter leak detector designed for monitoring filter leaks in real time. Cost-effective and low maintenance, it has been developed to continuously measure solid particles in a gas flow.

• Highly reliable dust filter detector: Designed for monitoring filter leaks in real time
• Cost-effective and low maintenance: Enables long-term dust trend detection for predictive maintenance, reducing servicing needs and minimizing total cost of ownership through early fault identification
  
• Triboelectric principle: Robust and reliable technology, reducing filter maintenance intervals, process down-time, and filter costs.

• Accurate detection
  Measurement range with detection as low as 0.01 mg/m³, ideal for precise dust emission monitoring
• Fast response to process changes
  Provides immediate feedback on shifts in dust levels, allowing rapid intervention
• No sample handling required
  Direct in-duct monitoring streamlines installation and reduces maintenance
• Low-maintenance design
  Real-time monitoring with practically no drift ensures reliable performance and minimal upkeep
• Long-term trend monitoring
  Supports ongoing analysis of dust levels for efficient process control and preventive maintenance
• Built for harsh environments
  IP66 rating
• Early filter leak detection
  Rapid response to dust level changes helps prevent significant emissions, supporting compliance and avoiding product loss
• Improved process efficiency
  Continuous, real-time data on dust trends allows for optimized filtration cycles, which improves equipment longevity and reduces downtime
• Cost-effective maintenance
  Early detection of filter wear or failure minimizes the need for emergency repairs, and preventing costly disruptions promoting efficient maintenance
• Environmental and operational responsibility
  Accurate monitoring and control of emissions help industries meet environmental standards and improve overall plant efficiency

• Filter leak detection and dust arrestment plant management
  Ideal for monitoring industrial filtration systems such as baghouses, cyclones, and exhaust ducts, where precise dust emission control is required
• Process control and trend monitoring
  Used in various industries to maintain filtration efficiency, prevent product loss, and monitor system disruptions such as ventilation interruptions or cleaning cycle issues
