Pleated Bags Improve Dust Collection Performance at Novamet Specialty Products
Industry: Metal Powders & Specialty Materials Manufacturing
Application
Nickel Powder and Metallic Material Dust Collection
Case Study Highlights
TubeJet® collectors installed
Operating since 2006
Monthly pulse cleaning only
Improved product recovery efficiency
Utility savings through air recirculation
The Challenge:
Frequent Maintenance and Product Loss from Existing Dust Collectors
Novamet Specialty Products manufactures precision-engineered nickel powder, metallic flake, coated materials, and nickel oxides. Efficient dust collection and recovery of valuable materials were critical requirements for the process. Existing cartridge and baghouse collectors created operational and maintenance challenges.
Problems included:
- Frequent filter replacements required
- Valuable product trapped in filters
- Messy collector maintenance procedures
- Ongoing air quality permit requirement
Previous collectors required annual filter replacements, creating maintenance difficulties. Some systems are also exhausted through roof stacks, increasing permitting requirements and operational complexity.
The Solution:
TubeJet® Dust Collectors with Pleated Filter Bags
Sly representative Joe Caccamese of Cino Equipment recommended Sly’s TubeJet dust collectors equipped with pleated filter bags. Although Novamet initially associated pleated bags with previous cartridge collector issues, the pleated bag configuration became the preferred solution due to limited headroom within the facility.
This approach provided several advantages:
- Reduced maintenance requirements
- Improved product recovery capability
- Vertical filter removal configuration
- Safe filtered air recirculation
Sly also supplied custom HEPA housing transitions, allowing Novamet to mount HEPA filters directly on the fan discharge and safely recirculate filtered plant air for additional utility savings.

- Lower utility costs from heat recovery
Novamet reported significant savings due to filter longevity, reduced maintenance requirements, and the ability to safely recirculate filtered plant air.
Why TubeJet® Dust Collectors Work for Metal Powder Dust Collection Applications
TubeJet® dust collectors with pleated filter bags provide efficient filtration and recovery for valuable metal powders and specialty materials. The pleated bag configuration supports high filtration efficiency while accommodating facilities with limited headroom. Reduced cleaning frequency and long filter life also help minimize maintenance requirements and operational costs.
Foire aux questions
What are pleated filter bags used for in dust collection systems?
Pleated filter bags are used to improve filtration efficiency and increase filter surface area in compact dust collection systems.
How do pleated filter bags differ from cartridge filters?
Pleated filter bags use a different structural design that can improve maintenance access, filter life, and cleaning performance depending on the application.
Why is dust recovery important in metal powder manufacturing?
Recovering valuable metal powders helps reduce material waste and improve process efficiency.
What are the benefits of recirculating filtered plant air?
Recirculating filtered air can reduce energy costs by recovering conditioned plant air while maintaining filtration performance.
How often do pulse jet dust collectors require cleaning?
Cleaning frequency depends on the application, dust loading, and collector design. In this case, pulse cleaning occurred only once per month.
