Replacement for P191619 round flange dust filter cartridge. 12.75" OD x 26" L x 8.375" ID conical open-end design. 222.64 sq ft media. For industrial dust collectors.
Ayater supplies the interchangeable P191619 round flange dust filter cartridge manufactured in our ISO-certified Xinxiang facility. This conical replacement unit matches OEM specifications at 12.75" OD × 26" length with an 8.375" ID and 222.64 sq. ft. of effective media area. By sourcing directly from our factory, procurement teams gain competitive pricing, shorter lead times, and direct technical support. For non-standard collector housings, we accommodate dimensional modifications including alternative lengths, custom flange diameters, and specialty media grades – all verified for seamless drop-in compatibility with existing systems.
Power Generation – Coal-Fired Boiler Baghouse Pre-Collectors
Coal-fired utilities employ pulse-jet collectors ahead of main baghouses to reduce fly ash burden on downstream fabric filters. This round flange dust filter cartridge captures coarse ash particles efficiently, extending the service intervals of final-stage filtration and reducing outage frequency for maintenance.
Pharmaceutical Intermediates – Dry Powder Processing
API manufacturing facilities handling dry powder intermediates operate under strict containment requirements. This interchangeable conical filter with upgraded nanofiber media achieves fine particle capture appropriate for GMP-compliant environments, with smooth internal surfaces that resist material accumulation.

Chemical Processing – Powder Handling and Pneumatic Conveying
Chemical plants handling dry powders (e.g., catalysts, pigments, polymer additives) require reliable dust collection to protect product purity and worker safety. This replacement for P191619 provides high-efficiency particulate capture with low pressure drop, reducing energy consumption in pneumatic conveying systems while maintaining consistent air-to-cloth ratios.
Coal Mining and Processing – Crushing and Screening Operations
Coal preparation plants generate significant respirable dust from crushing, screening, and conveying. This round flange dust filter cartridge captures fine coal dust effectively, reducing explosion risks and improving air quality in confined processing areas. The open/open design enables straightforward installation in existing dust collector housings without modification.

A specialty graphite processing facility in the Pacific Northwest operates a centralized dust collection network serving milling, sizing, and packaging lines. Graphite dust is electrically conductive and inherently lubricious – properties that caused frequent collector fires from static discharge and rapid cartridge blinding from fine particle adhesion. The plant's engineering team replaced their existing filters with Ayater's replacement for P191619 conical alternative featuring conductive scrim reinforcement and an anti-adhesive surface treatment. Over 18 months of continuous monitoring, zero static-related ignition events were recorded, and average filter service life increased from 600 hours to over 1,800 hours. The facility reduced annual cartridge consumption by 4,800 units and eliminated downtime previously allocated to fire-safety inspections and emergency change-outs.
Ayater's Xinxiang production hub spans over 15600 sq. meters with dedicated cells for media pleating, end-cap fabrication, and sealant application. Our ISO 9001-registered workflows incorporate statistical process control at each stage. Every P191619-replacement batch undergoes burst-strength verification, pleat-spacing measurement, and flange-flatness inspection.
