The DMC-64 Type Pulse Opsinn Industrial Dust Collector Bag Filter with Dust Supporting Cage is a high-performance filtration system designed for heavy-duty industrial dust collection applications. Below is a detailed breakdown of its features, specifications, applications, and key considerations:
Product Overview
The DMC-64 is a pulse-jet baghouse dust collector featuring 64 filter bags arranged in a modular design. It utilizes compressed air pulses to clean the filter bags, ensuring continuous operation and high filtration efficiency even under high dust loads. The supporting cage inside each bag maintains structural integrity, preventing collapse during operation and cleaning cycles.
Key Features
High Filtration Efficiency
Captures ≥99.9% of particles ≥1μm (depending on filter media).
Suitable for fine dust (e.g., welding fumes, pharmaceutical dust, metalworking particles).
Pulse-Jet Cleaning System
Uses compressed air pulses to dislodge dust from filter bags, extending service life.
Automated cleaning reduces downtime and manual maintenance.
Dust Supporting Cage Design
Galvanized steel or stainless steel cages prevent filter bag collapse under negative pressure.
Venturi-style cages improve airflow distribution and cleaning efficiency.
Modular Construction
64-bag configuration allows for scalable dust collection capacity.
Compact footprint suitable for indoor or outdoor installation.
Durable Filter Media Options
Polyester, Nomex, or PTFE-coated fabrics for high-temperature or chemical-resistant applications.
Antistatic or flame-retardant treatments available for hazardous environments.
Low Pressure Drop
Optimized airflow design minimizes energy consumption.

Chemical Industry: Handling corrosive or toxic dust.
Cement & Minerals: Limestone, gypsum, or silica dust collection.
Woodworking: Sawdust and shavings from CNC routers or sanders.
Power Generation: Fly ash or coal dust control.
Advantages
High Efficiency: Continuous operation with minimal downtime due to automated cleaning.
Cost-Effective: Long filter life reduces replacement frequency.
Versatile: Adaptable to various dust types and operating conditions.
Compact Design: Space-saving compared to traditional baghouses.
Key Considerations
Filter Media SelectionChoose based on dust type, temperature, and chemical resistance:
Polyester: General-purpose, up to 130°C.
Nomex: High-temperature resistance (up to 200°C).
PTFE-coated: Chemical-resistant and hydrophobic.
Compressed Air Quality
Use dry, oil-free compressed air to prevent bag damage or contamination.
Cage Compatibility
Ensure the cage diameter matches the filter bag to prevent leaks or abrasion.
Maintenance Access
Design should allow easy access for bag replacement and cage inspection.
Explosion Protection (if required)
For combustible dust (e.g., wood, flour), install explosion vents or suppression systems.
Maintenance & Troubleshooting
Regular Inspections: Check for bag tears, cage corrosion, or air leaks.
Pulse Timing Adjustment: Optimize cleaning cycles to balance efficiency and bag life.
Differential Pressure Monitoring: Replace bags when pressure drop exceeds 1,500–2,000 Pa.
Customization Options
Bag Material & Coatings: Antistatic, flame-retardant, or PTFE membranes.
Cage Design: Venturi-style or standard cylindrical cages.
Dust Discharge Systems: Rotary valves, screw conveyors, or pneumatic transport.
