How RABH Filter Bags Work in Reverse Air Baghouses
Aokai manufactures custom reverse air filter bags and replacement RABH filter bags for industrial baghouse dust collectors. RABH stands for Reverse Air Bag House, a dust collection system that uses low-pressure reverse airflow to clean the filter bags.
Reverse Air Filter Bags are specially designed filtration bags used in reverse air baghouse dust collection systems.
In a reverse air dust collector, low-pressure reverse airflow is used to clean the filter bags, which provides gentle cleaning performance and helps extend the service life of the filter media. Compared with pulse jet systems, reverse air systems typically operate under lower filtration velocity and are suitable for handling large air volumes and high-temperature dust.
How are reverse air filter bags different from pulse jet filter bags?
Reverse air filter bags are typically suspended from the top and use support rings to maintain their shape during cleaning. Pulse-jet filter bags are usually supported by internal filter cages and cleaned with compressed-air pulses.
Reverse Air Filter Bag Construction and Fit
Engineered for high-temperature baghouse operations with reverse air cleaning systems. Designed with Support-ring configuration customized to bag length and collector design, superior structural stability, and customized membrane options for unmatched particulate filtration down to sub-micron levels.

Reverse Air Filter Bag FAQs
A reverse air filter bag is a tubular filter element used in reverse-air baghouse dust collectors. It is cleaned by low-pressure airflow in the opposite direction of normal filtration.
Reverse air filter bags are typically suspended from the top and use support rings to maintain their shape during cleaning. Pulse-jet filter bags are usually supported by internal filter cages and cleaned with compressed-air pulses.
Yes. We can reproduce reverse air filter bags from old samples, drawings or photographs and match dimensions, support-ring layout, upper suspension and lower connection details.
The suitable media depends on operating temperature, gas chemistry, moisture, dust abrasion, cleaning conditions and emission requirements. Common options include woven fiberglass, aramid, PPS, PTFE, polyester and acrylic.
Many reverse air bag designs use support rings to help prevent excessive collapse and maintain bag shape during reverse-air cleaning. Ring size, material and spacing should be matched to the baghouse design.
Please provide bag size, quantity, photos or drawings, top and bottom construction, support-ring details, operating conditions and any existing filtration problem.
