Reverse Air Collectors
Longer Filter Life. High Energy Efficiency.
Reverse Air Collector: Efficient Dust Collection Solution
When energy savings are critical or the availability of quality compressed air is limited, the Sly RAC (reverse air collector) is an ideal option. The RAC uses an integral centrifugal fan to deliver low pressure reverse air to clean the filter bags and does not require compressed air. The advanced cleaning arm with high velocity nozzles rotates continuously providing clean, dry, contaminate free air to each filter bag. The cleaning arm is powered by a direct drive providing long reliable service and carries a 5-year warranty.
Sly’s Reverse Air baghouse dust collector excels in challenging applications such as grain, woodworking, recycling, aggregate, and more. The entire baghouse can stay online while cleaning the filters, which are all constantly in operation. With a longer filter life, high energy efficiency, and customization options, the RAC offers excellent value and quality.

FAQs – Reverse Air Collectors
What is a reverse air dust collector?
A reverse air collector cleans filter bags by reversing airflow through the bags rather than using compressed air pulses.
When should a reverse air collector be used instead of a pulse jet baghouse?
Reverse air collectors are often preferred when compressed air is limited or energy savings are a priority, since they do not rely on pulse air systems.
What types of processes use reverse air collectors?
These systems are commonly used in continuous industrial processes such as cement production, power generation, and large material handling systems.
Do reverse air collectors operate continuously?
Yes, most reverse air collectors clean compartments sequentially, allowing the system to continue operating while individual sections are cleaned.
What are the maintenance considerations?
Reverse air systems typically use longer filter bags and fewer moving parts, which can reduce maintenance requirements compared to other baghouse designs.
