High-Efficiency Polypropylene Filtration Solutions
At Purecowater, we specialize in providing top-tier filtration solutions for complex industrial challenges. Among our premier offerings are the AJR Filtration PPO Series Pleated Filter Cartridges. Designed for superior versatility and efficiency, these cartridges are an essential component for critical liquid filtration processes across various industries.

Product Overview
The AJR PPO (Polypropylene) Series consists of high-purity, pleated liquid filter cartridges. Unlike standard string-wound or depth filters, the PPO Series utilizes a pleated design that significantly increases the effective surface area. This design enhancement allows for higher flow rates, improved dirt-holding capacity, and lower initial pressure drops.
Constructed from 100% polypropylene materials, these cartridges offer broad chemical compatibility, making them suitable for aggressive chemical filtration as well as sensitive food and beverage applications. According to data from filtrationworld.com, the PPO series is available in micron ratings ranging from as low as 0.2 up to 40 microns, ensuring precise contaminant removal.
Key Features & Benefits
- 100% Polypropylene Construction: Ensures compatibility with a wide range of process fluids, acids, bases, and solvents.
- High Surface Area: The pleated media design maximizes the filtration area, leading to longer service life and reduced change-out frequency compared to depth filters.
- Low Pressure Drop: Engineered to maintain high flow rates with minimal energy loss.
- Versatile Configurations: Available in standard 2.5-inch and 2.75-inch diameters (PPOW) and various lengths to fit most industrial filter housings.
- Fixed Pore Structure: Prevents unloading of contaminants under high differential pressure.

Common Applications
Due to their purity and rugged construction, AJR PPO cartridges are deployed in a variety of critical sectors:
- Reverse Osmosis (RO) Pre-Filtration: Protecting expensive membrane elements from particulate damage.
- Food & Beverage: Filtration of potable water, beverages, and liquid foods (FDA listed materials often available).
- Chemical Processing: Clarification of acids, bases, plating solutions, and solvents.
- Electronics: High-purity water filtration for circuit board manufacturing.
- Oil & Gas: Filtration of produced water and completion fluids.
For applications requiring higher sediment holding capacity or alternative media, we also supply depth filters and other specialized configurations.
