P191531 Polyester Fiber Dust Filter Cartridge

This product is engineered as a direct replacement for P191531, maintaining original equipment performance standards in industrial dust collection. Featuring 240.97 sq ft of polyester fiber media, this Polyester Fiber Dust Filter Cartridge optimizes both dust-holding capacity and airflow efficiency. With open top and bottom ends, it integrates seamlessly into existing collector housings. Backed by Ayater's precision manufacturing, this replacement element is designed to maintain consistent differential pressure performance and support extended service intervals.

1. Balanced Filtration Efficiency for Dry Dust
This replacement for P191531 uses a spun-bond polyester media formulation that targets dry particulate matter commonly found in material handling. The 240.97 sq ft pleated surface area facilitates depth-loading, trapping sub-micron particles while keeping pressure drop in check. This makes it a practical choice for facilities needing compliance with workplace exposure limits without oversizing their fan systems.

2. Dimensional Precision for Drop-In Installation
Interchangeable with OEM P191531, this filter matches the exact physical profile: 13.8" OD, 26" length, and 9.479" ID. The open-end geometry mimics the original design, ensuring proper sealing and alignment within tube sheets. Maintenance crews can execute changeouts without modifying ductwork or mounting hardware, reducing machine downtime during scheduled service.

A Texas mineral processing plant operating a barite grinding mill faced monthly filter changeouts due to uneven dust loading and high differential pressure spikes that tripped their mill interlock system. After converting to Ayater's replacement for P191531 Polyester Fiber Dust Filter Cartridge, the plant extended service intervals from 30 to 55 days-an 83% increase. Average differential pressure stabilized at 6.5 in.WC, below the 9 in.WC trip setpoint, and annual maintenance man-hours dropped by approximately 40 hours. The facility has since converted all five grinding lines to this replacement cartridge.

Selecting the right replacement for P191531 requires understanding three key operating parameters. For filtration velocity, the recommended air-to-cloth ratio for this 240.97 sq ft cartridge falls between 3:1 and 4:1 (ft/min) for pulse-jet systems-exceeding 4.5:1 may accelerate dust migration and increase residual pressure drop. For cleaning pressure, optimal pulse pressures range from 70 to 90 PSI depending on nozzle diameter, though fine cohesive dust may perform better at 60-70 PSI while abrasive minerals often require 90-100 PSI. For moisture prevention, while polyester resists humidity, liquid water causes media blinding; outdoor installations should maintain inlet temperature 15°F above dew point to prevent condensation.
