When selecting air filtration and dust collection systems for your facility, performance, reliability, and safety are key engineering requirements. In properly engineered resin conveying and blending solutions, air filtration units play a critical role in protecting vacuum pumps while maintaining clean airflow throughout the conveying network.
Advanced Blending Solutions (ABS) air filtration units are built to exceed those expectations with intelligent design and operator-centric features to improve efficiency. The unit is engineered for use in conveying bulk materials with particle sizes as small as 10 microns. It can operate at vacuum levels up to 16 inches of Mercury. These air filtration units can be used in both vacuum conveying systems and pressure conveying systems within pneumatic conveying applications.
Why Air Filtration Matters in Pneumatic Conveying Systems
Air filtration units are essential components in pneumatic conveying systems used in plastics processing plants. During normal operation, pellet abrasion, grinding operations, and powder handling can generate fine particles that travel through the conveying air stream. These airborne particles are commonly referred to as pellet fines or conveying dust, and if not removed they can accumulate in pipelines, loaders, and vacuum pumps.
Without proper filtration, these particles can:
- contaminate downstream equipment
- damage vacuum pumps
- increase maintenance requirements
- reduce conveying efficiency
Air filtration units remove these particles before the air stream enters the vacuum pump, protecting equipment and maintaining stable airflow throughout the conveying system.

1. Optimized Airflow = Maximized System Performance
Engineers know that pressure drop across filters is the silent killer of system efficiency of pneumatic conveying system efficiency. Airflow stability is especially important in pneumatic conveying systems, where vacuum pump performance directly influences conveying reliability and material flow. As discussed in our article on vacuum pump performance in resin conveying systems, selecting the correct pump technology can dramatically improve conveying efficiency and reduce energy consumption. ABS air filtration units are designed to minimize airflow restrictions in pneumatic conveying systems, ensuring that blowers operate with optimal performance. This reduces energy consumption, protects downstream equipment, and helps maintain consistent air quality.
Key Design Features:
- Streamlined flow paths to reduce turbulence and pressure loss
- Filter configurations designed to minimize clogging and extend service life
- Precise sizing options to match system airflow requirements
Effective filtration also helps reduce contamination caused by pellet fines and angel hair formation in resin conveying systems, which can accumulate in conveying lines and downstream equipment.
2. Delta P Monitoring for Data-Driven Maintenance
Forget arbitrary filter changes or inefficient timed cleanings! ABS air filtration units use precise delta P (∆p) measurements to monitor pressure drop across the filters in real time.
Why It Matters to Engineers:
- Enables on-demand cleaning cycles, reducing compressed air usage
- Extends filter life and reduces maintenance intervals
- Supports predictive maintenance strategies and minimizes unplanned downtime
3. Designed for Easy Access and Fast Servicing
Maintenance accessibility is often overlooked until it becomes a problem. ABS air filtration units solve this with thoughtful mechanical design.
Ease-of-Use Features:
- Front-access doors for quick inspections and filter replacements
- Quick-release clamps for tool-free filter changes
- Auto blow off for automated filter cleaning based on pressure monitoring
- Removable collection bins for clean and efficient waste removal
- Collection bin automation (optional) for knife-gate activated waste discharge into a customer’s gaylord bin – no labor required
These features directly translate to reduced labor costs and faster turnaround during servicing.

4. Safety for Combustible Dust & Robust Design
If your process involves combustible dust, safety compliance is non-negotiable. ABS offers NFPA-compliant systems rated up to ST2 Hazard-Class materials, ensuring peace of mind and regulatory alignment when working with combustible dust.
Engineered Safety Features:
- Pressure relief valves to handle excess pressure
- Burst panel to protect against explosions
- CE-compliance for international applications
- Heavy gauge sheet metal for extreme vacuum conditions associated with dilute phase conveying.
These safety features are particularly important in plastics processing environments where resin dust or polymer powders may present combustible dust hazards.
The ABS Air Filtration Unit is designed to keep plant personnel safe.
5. Custom Configurations for Engineered Systems
ABS understands that no two processes are the same. That’s why ABS air filtration units are offered in multiple sizes, filter types, and inlet/outlet options, to work with pumps rated from 5 to 100 HP.
Customizable Parameters:
- Diameter sizes: 16″, 24″, and 32″
- Filter options: 16oz Polyester Felt Bags or PTFE-membraned Pleated Filters
- Inlet/outlet sizes and breaker valve availability
These flexible configurations allow engineers to integrate ABS units into both standard and specialized applications without compromise. Proper sizing of the conveying airflow and filtration system is also essential, particularly in systems driven by industrial vacuum pumps. Engineers designing new systems can estimate airflow requirements using our vacuum pump sizing calculator.
Typical Applications for Air Filtration Units
Air filtration units are commonly installed in pneumatic conveying systems used throughout plastics manufacturing facilities.
Typical applications include:
- Plastic pellet conveying systems
- Resin drying and blending operations
- Centralized vacuum conveying systems
- Grinding and regrind recovery systems
- Powder handling in compounding plants
By removing fines and airborne particles, filtration units help maintain system efficiency while protecting pumps and downstream equipment.
In pneumatic conveying systems used for plastics processing, air filtration units serve three critical functions: removing pellet fines from the airflow, protecting vacuum pumps from contamination, and maintaining stable conveying performance.
Conclusion: A Practical Solution to Complex Air Filtration
Selecting the right air filtration system for pneumatic conveying involves more than just meeting minimum requirements. It’s about designing for long-term efficiency, maintainability, and compliance. ABS air filtration units offer a solution grounded in engineering fundamentals: optimized airflow, intelligent filter monitoring, accessible serviceability, and safety features aligned with NFPA standards.
For engineers seeking to balance performance, regulatory compliance, and system longevity, ABS DCUs present a well-rounded, configurable platform adaptable to a wide range of industrial applications.
As always, final selection should consider specific process variables, dust characteristics, and facility layout. However, for many engineered systems, ABS provides a reliable and proven starting point.
