Bulk Material Handling and Dust Collection Division

Metal structures and stairs give safe access to bulk handling equipment such as dust collectors, silos, conveyors and filters. Platforms, ladders and stairs support inspection and maintenance at height.

Products Available

• Access platforms – service equipment safely
• Stairs and ladders – OSHA-compliant access
• Support structures – mount collectors and silos
• Handrails and safety gates – fall protection
• Galvanized and painted finishes – corrosion protection

Planning Access

Consider equipment layout, maintenance points, loads and code requirements. Modular structures install faster than custom fabrication.

Centro supplies metal structures and stairs for equipment access.

Expansion joints are essential for piping and ducting systems, designed to handle thermal expansion, contraction, vibration, and other dynamic movements. Expansion joints are vital in preventing damage caused by temperature changes and mechanical stress, ensuring the integrity and efficiency of the systems. Available in various types, including metal, rubber, and fabric, each type is designed for specific applications and environments. By accommodating movement and reducing stress, expansion joints help extend the lifespan and reliability of infrastructure in industries like construction, power generation, chemical processing, and water treatment. Choosing and installing the right expansion joints is crucial for optimal system performance and safety.

Ducting carries dust, fumes and particulate from the point where they're generated to your dust collector. Good duct design keeps air velocity high enough to hold dust in suspension, which prevents buildup, keeps hoods working and protects workers.

Ducting Components

• Quick-fit clamp-together duct – modular, easy to reconfigure and expand
• Spiral and welded duct – permanent systems for heavy dust loads
• Elbows, branches and reducers – smooth transitions that limit pressure loss
• Blast gates and dampers – balance airflow between drops
• Flexible hose and hoods – capture dust at the source

Design Considerations

Size ducts to keep the right conveying velocity for your dust, typically 3,500 to 4,500 feet per minute for most industrial dusts. Use long-radius elbows and 30° or 45° branch entries to cut losses. For combustible dust, include grounding, explosion isolation and NFPA-compliant design.

Centro can help you lay out dust collection ducting matched to your collector and production equipment.

Dust personnel cleaning systems remove dust from workers' clothing safely before they leave dusty areas. They replace unsafe compressed air blow-off and help keep dust from spreading through the facility.

System Types

• Cleaning booths – enclosed, filtered cleaning stations
• Safety air showers – controlled airflow cleaning
• Vacuum-based systems – capture dust at the source
• OSHA-compliant nozzles – safe pressure levels

Benefits

Personnel cleaning cuts dust exposure, keeps contamination out of clean areas and supports OSHA compliance in industries like foundries, mining, woodworking and food processing.

Centro supplies dust personnel cleaning systems.

Dust filtration cartridges are pleated filter elements used in cartridge-style dust collectors. Their large media area captures fine dust efficiently in a compact footprint.

Cartridge Options

• Cellulose blend media – economical general-purpose filtration
• Spunbond polyester – moisture resistance and easy pulse cleaning
• Nanofiber media – high efficiency for fine dust
• PTFE membrane cartridges – sticky or very fine particulate
• Flame-retardant media – welding and hot sparks

Choosing Replacement Cartridges

Match cartridge dimensions, end cap style and gasket to your collector. Choose media based on dust type, moisture and efficiency requirements. Replace all cartridges at the same time for balanced airflow.

Centro supplies replacement dust collector cartridges for many collector brands.

Dust collectors capture airborne dust and particulate from cutting, grinding, mixing, conveying and packaging operations. They protect workers' health, keep facilities clean and help you meet OSHA and EPA requirements.

Dust Collector Types

• Cartridge collectors – compact, high-efficiency for fine dust
• Baghouse collectors – heavy dust loads and high temperatures
• Cyclones – pre-separation of coarse particles
• Bin vents – filter displaced air from silos and hoppers
• Portable collectors – source capture at individual workstations

Sizing a Collector

Sizing depends on airflow (CFM), dust type and loading, and the required air-to-cloth ratio. Combustible dust requires NFPA-compliant design with explosion venting or isolation. Pulse-jet cleaning keeps filters performing between changes.

Centro can help you size a dust collector and supply replacement cartridges, bags and ducting.
