Everything You Need to Know About the AquaStar Pipeline Filter
The AquaStar Pipeline filter is one of the most efficient and maintenance-friendly cartridge filters on the market today. Built for both commercial and residential pools, it delivers DE-level clarity in a compact design using just one cartridge element. With powerful flow performance, extended cleaning cycles, and industry-certified clarity, this filter is quickly becoming a top choice for pool professionals and homeowners looking to upgrade their system.
Whether you're maintaining a small hotel pool or a residential backyard setup, the AquaStar PLF35000 and PLF27000 provide maximum performance with minimum effort.
Built for Large Pools, Designed for Tight Spaces
The AquaStar Pipeline series offers two high-capacity models to fit different pool sizes and installation needs:
PLF35000 is rated for up to 35,000 gallons in commercial applications and 144,000 gallons in residential pools
PLF27000 is rated for up to 27,000 gallons in commercial applications and 108,000 gallons in residential pools
Both models use a single oversized cartridge and are ideal for high-traffic pools that need strong filtration without taking up unnecessary space. Their compact equipment footprint makes them perfect for pad retrofits, tight plumbing layouts, or installations where space is limited.
Certified DE-Level Clarity in Just One Turnover
Unlike traditional cartridge filters, which often require three to five turnovers to match DE clarity levels, the AquaStar Pipeline achieves certified clarity in just one turnover. This is a significant advantage for users who want faster water polishing, reduced pump run times, and more efficient sanitization.
The internal design of the Pipeline system promotes uniform water flow across the full surface of the cartridge, allowing for better particulate capture in a single pass. It’s this design that earned the filter NSF certification for DE-level performance without using DE powder.
One Cartridge, Less Hassle, Lower Cost
A standout benefit of the AquaStar Pipeline filter is its use of a single, oversized cartridge element. This eliminates the need for multiple cartridges or complex grids, which can be time-consuming and expensive to clean or replace.
The simplified internal layout means easier service, fewer parts to maintain, and faster filter changes. Over time, this translates into reduced maintenance costs and fewer interruptions during the swim season.
After the first cleaning cycle, the filter continues to outperform systems twice its size, both in terms of hydraulic flow and dirt-holding capacity.
Hydraulic Performance That Stays Consistent
Both the PLF35000 and PLF27000 are engineered to operate at high flow rates while minimizing pressure loss. Their large-diameter cores feature wide openings that reduce resistance and maintain strong flow, even as the cartridge begins to load with debris.
This results in a more efficient filtration cycle and helps reduce overall pump energy use. Even after repeated cleanings, the filters continue to operate within their performance window, which is critical for long-term clarity and equipment longevity.
The design also limits PSI increases after cleaning, maintaining steady pressure levels over time—a major benefit for systems sensitive to flow changes.
Durable Build, Long-Term Reliability
AquaStar Pipeline filters are constructed from high-strength polymer designed to withstand UV exposure, heat, and pressure. Each unit features a self-aligning base for easy installation, a locking collar system for safe depressurization, and an accessible drain plug with included wrench.
These design details make servicing the unit fast and frustration-free, whether you're doing a quick rinse or a full cartridge replacement.
Additional built-in features include a stainless-steel pressure gauge with protective rubber housing and a manual air relief valve for safe operation.
Real-World Performance Backed by Pool Pros
"Let this sink in—7 months, no cleaning, a 15K-gallon pool running through a blazing hot Texas summer with no changes in PSI or water clarity."
That’s a direct testimonial from a pool technician who installed the PLF35000 and ran it through extreme conditions. It’s one thing to see strong numbers in lab tests, but this filter also holds up in real backyard pools with real-world usage.
Its extended cleaning cycles are a major benefit for both service professionals and homeowners who want to cut down on routine maintenance without compromising water quality.
