Drop Out Box Dura-Box DBX Series
The Dura-Box DBX Series is a large particulate drop out box designed to work inline with ductwork and remove heavier material before it reaches the primary dust collector. By slowing the airstream at the inlet deflection plate, the unit helps separate larger particles into the hopper and collection bin, reducing filter loading and helping extend filter life.

The Dura-Box DBX Series is a self-contained drop out box used ahead of an industrial dust collector to remove larger particulate from the air stream. It is designed for easy installation in new or existing dust collection system layouts and is a practical way to improve material separation before air continues to the main collector.
Dura-Box DBX Range
- 1,000 to 10,000 CFM
- Inline ductwork installation
- Large particulate separation
- 1 to 2 in. wg pressure consumption
- Great for new or existing dust collection systems
The Dura-Box series is available with safety options such as explosion venting for applications involving combustible dust. Final equipment selection should be based on the specific material being collected, process conditions, and overall system design requirements.
The Dura-Box DBX Series is well suited for applications where larger particulate should be removed before it reaches the primary dust collection equipment. It is commonly used in systems that benefit from pre-separation, reduced filter loading, easier material reclamation, and longer filter life.
Common Applications
- Inline pre-separation
- Existing dust collection system upgrades
- New dust collection system installations
- Large particulate removal
- Material reclamation applications
The Dura-Box combines simple operation, durable construction, and practical system protection in one pre-separation unit. With no moving parts, solid welded steel construction, and a replaceable stainless steel inlet deflection plate, it offers a low-maintenance way to reduce the particulate load on the primary collector and improve long-term filter longevity.
Standard Features
- Self-contained design
- No moving parts
- Solid welded steel
- Replaceable stainless steel inlet deflection plate
- Easy installation
- Increases filter longevity
- Great for new or existing dust collection systems
The Dura-Box DBX Series is designed to operate inline with the duct system and reduce air velocity as particulate enters the box. Larger particles drop into the hopper and collection bin, while smaller dust continues downstream to the dust collector. Operating ranges from 1,000 to 10,000 CFM with low pressure consumption of approximately 1 to 2 inches wg.
Performance Range
- 1,000 to 10,000 CFM
- 1 to 2 in. wg pressure consumption
- Large particulate drop out
- Reduced loading on primary filters
- Improved filter longevity
ProVent industrial dust collectors and system components are built for practical performance, durable construction, and easier long-term maintenance. The Dura-Box DBX Series gives facilities a simple way to improve pre-separation, reduce filter loading, and support better performance from the main dust collection system.
Why ProVent
- Simple inline pre-separation
- Heavy-duty welded construction
- Low-maintenance design
- Helps extend filter life
- Works with new or existing systems
