Next-Generation Baghouse Efficiency with High-Surface-Area Pleated Elements
Skytech Ultrafab Pleated Dust Collection Bags replace multiple conventional round bags with a single high-surface-area pleated unit, dramatically reducing the number of filter elements, lowering compressed-air cleaning consumption, and extending maintenance intervals. The stainless steel internal cage with PTFE-laminated polyester pleated media delivers superior filtration efficiency at a lower air-to-cloth ratio. Ideal for retrofit upgrades of existing pulse-jet baghouses in cement, mining, food, pharmaceutical, and general industrial dust collection.
What Are Pleated Dust Collection Bags?
Pleated dust collection bags are oval or round filter elements designed to replace conventional cylindrical needle-felt bags in pulse-jet baghouse tube sheets. By folding the filter media into pleats within the same housing footprint, each pleated bag delivers 3 to 5 times more filtration area than the felt bag it replaces. This means fewer filter elements are needed for the same airflow, cleaning pulse frequency drops, compressed air consumption falls, and filter service life extends — all without modifying the existing baghouse structure.
Pleated Dust Collection Bags
Features and Benefits
-
3–5× More Filtration Area:
Pleated geometry delivers 3–5 times the media area of a conventional felt bag in the same tube-sheet hole — directly reducing air-to-cloth ratio and extending service life
-
Fewer Elements Required:
One pleated bag can replace 3–5 conventional bags — reducing the number of snap rings, cages, and tube-sheet penetrations that require maintenance
-
Lower Compressed Air Consumption:
Larger media area requires less frequent pulse-jet cleaning cycles — reducing compressed air consumption by 40–60% compared to equivalent felt bag installations
-
ePTFE Membrane Surface Filtration:
PTFE membrane on the media surface prevents dust penetration into the media depth — enabling complete dust cake release with each cleaning pulse for consistently low pressure drop
-
Stainless Steel Internal Cage:
Rigid SS wire cage maintains pleat geometry and element roundness under pulse-jet cleaning shock loads — critical for long-term pleated bag structural integrity
-
Direct Retrofit:
Pleated bags manufactured to fit existing tube-sheet hole sizes — no baghouse structural modification required for retrofit installation

Applications
-
Cement Industry:
Retrofit of raw mill, kiln, and clinker cooler baghouses — pleated bags reduce cleaning frequency and extend intervals between baghouse maintenance shutdowns
-
Mining and Minerals:
Upgrade of crusher, conveyor, and ore processing dust collection systems to improve emission compliance and reduce filter maintenance costs
-
Food and Grain Processing:
PTFE membrane pleated bags for grain elevator, milling, and food dust collection — clean pulse release prevents product contamination in food-contact dust streams
-
Pharmaceutical Manufacturing:
cGMP-compliant pleated bags for API and potent compound dust collection where low emission and complete cleaning between product batches are mandatory
