Key Features Absolute Polypropylene sediment filter cartridges
Manufactured using advanced extrusion and injection technology
True depth filtration for superior particle retention
High flow rates with low pressure drop
Longer operational life, reducing replacement frequency and overall cost
Chemically resistant and suitable for a wide range of applications
Advantages of 40-Inch PP Depth Filter Cartridges
1. High Dirt-Holding Capacity
The 40-inch length provides a larger filtration surface area, allowing the cartridge to trap more sediment throughout its depth. This results in longer service life and fewer change-outs.
2. Superior RO Protect Clean N Series Depth Filtration
Manufactured from graded-density polypropylene microfibers, these cartridges capture particles progressively from the outer to inner layers, ensuring efficient removal of fine and coarse contaminants without premature clogging.
3. Reduced Operating Cost
Longer cartridge life and higher contaminant retention lower replacement frequency, reducing labor, downtime, and consumable costs—especially in high-flow industrial systems.
4. High Flow Rates
The extended length supports higher flow capacity with low pressure drop, making 40-inch sediment filter cartridges ideal for large-volume and continuous filtration applications.
5. Chemical & Thermal Resistance
Pure polypropylene construction offers excellent resistance to a wide range of chemicals and is suitable for demanding industrial environments.
6. Safe & Clean Filtration Media
100% polypropylene
No binders, adhesives, or additives
Free from extractables, lubricants, and wetting agents
Suitable for potable water and sensitive process applications
7. Ideal for Multi-Cartridge Housings
40-inch cartridges are designed for industrial multi-round housings, making them perfect for:
Consistent Filtration Performance
Advanced extrusion technology ensures uniform pore structure, providing stable and repeatable filtration efficiency throughout the cartridge life.
Disadvantages of 40-Inch PP Depth Filter Cartridges
• Not Cleanable or Reusable
PP depth cartridges are disposable and cannot be backwashed or regenerated, unlike some pleated or washable filter designs
- Higher Initial Cost
40-inch cartridges are more expensive upfront than 10″ or 20″ cartridges due to increased material usage and manufacturing cost.
- Larger Housing Requirement
They require industrial-grade, multi-round housings, which:
Take up more installation space
Have higher housing and piping costs
- Handling & Replacement Difficulty
Due to their length and weight:
Installation and removal can be physically challenging
Often require two-person handling in multi-cartridge systems
Increase maintenance time compared to shorter cartridges
- Not Ideal for Low-Flow Applications
For small or low-flow systems, 40″ cartridges may be overdesigned, leading to unnecessary capital and operating expenses.
- Disposal Volume
Longer cartridges generate more solid waste per replacement, which can be a concern in facilities with strict waste-management policies.
- Pressure Drop Sensitivity
If incorrectly selected (micron rating or flow rate too high), clogging can cause:
Rapid pressure increase
Reduced system efficiency
Proper pre-filtration and sizing are critical.
- Limited Flexibility in System Design
Compared to modular 10″ or 20″ systems, 40″ cartridges offer less flexibility when scaling small systems or retrofitting existing installations.
