What Are Cylinder Screen Packs?
Cylinder screen packs are specialized filtration elements designed for advanced extrusion systems that utilize cylindrical filtration chambers rather than flat breaker plates. These precision-engineered components feature carefully selected mesh configurations arranged in a cylindrical form factor, providing superior filtration while maintaining optimal polymer flow in specialized extrusion equipment.
At Rowe Equipment, we manufacture premium cylinder screen packs for all major equipment manufacturers including Keifel, Hosokawa-Alpine, JSW, Windmoeller, Gloucester, and many others. Our cylinder packs are custom-engineered to provide the exact filtration characteristics needed for your specific polymer, equipment, and product quality requirements.
Unlike flat extruder screens, cylinder screen packs create a radial filtration pattern that distributes pressure more evenly and provides increased filtration surface area. This specialized design enables more efficient contaminant removal, improved pressure stability, and enhanced product quality in applications where traditional flat screens are not suitable.

Frequently Asked Questions About Cylinder Screen Packs
How do I identify the right cylinder pack specifications for my equipment?
Start by gathering information about your equipment manufacturer, model, and filtration chamber dimensions. Our technical team can work from your current cylinder specifications or directly from equipment documentation. For many common systems, we already have the specifications on file. We’ll help determine the exact dimensions, end cap configuration, and mounting system needed for your specific equipment.
What mesh configuration will work best for my polymer and application?
The optimal mesh configuration depends on several factors including polymer type, processing temperature, contamination profile, and product quality requirements. Our technical team evaluates these factors to recommend the ideal configuration. We typically start with proven configurations for similar applications and fine-tune based on your specific needs. Factors we consider include melt flow rate, typical contaminant types, quality specifications, and pressure limitations.
How do cylinder packs compare to flat screen packs in terms of performance?
Cylinder screen packs offer several advantages over flat packs in appropriate applications. The cylindrical design provides significantly more filtration surface area, which typically results in longer service life and more stable pressure characteristics. The radial flow pattern often creates more uniform polymer distribution and more consistent filtration. However, cylinder packs are generally more complex and equipment-specific than flat screens. Our team can help you evaluate the best option for your particular process.
Can you match the exact specifications of our current cylinder packs?
Yes. Rowe Equipment specializes in manufacturing exact replacements for OEM cylinder packs. We can work from samples, specifications, or equipment documentation to create precision matches for your current filtration components. Many customers find that our custom-engineered replacements actually outperform original equipment components due to our specialized mesh selection and advanced manufacturing techniques.
How quickly can you deliver custom cylinder packs?
Delivery timeframes depend on complexity and customization requirements. For common equipment types, we often have standard configurations available for immediate shipment. Custom designs typically require 3-5 business days. For urgent requirements, we offer expedited manufacturing and shipping options. We can also establish inventory management programs for high-volume customers, ensuring consistent availability while minimizing on-site inventory requirements.
Can cylinder packs be cleaned and reused?
While cleaning and reuse are technically possible, most customers find that the cleaning process is not cost-effective and may compromise filtration performance. The complex structure of cylinder packs makes thorough cleaning difficult, and residual polymer is challenging to remove completely. For consistent quality and performance, we recommend using new cylinder packs for each production cycle. However, for specialized applications where reuse is necessary, we can provide guidance on appropriate cleaning procedures.
