Engineered for durability and consistent flow
- Reinforced center cores provide even stress distribution and higher debris loading. The extruded PVC center cores help prevent collapse under heavy filtration demands, meaning fewer cleanings and less downtime.
- Wider support bands keep pleats evenly spaced, reducing flutter and ensuring steady, optimum flow through the cartridge.
- Sharp pleat folds with a unique synthetic fiber construction prevent bridging, allowing dirt to penetrate deep into the folds for stronger filtration and easier cleaning.
Superior filtration media that lasts
- Durable polyester media delivers dependable filtration performance, helping to maintain water clarity over time and extending cartridge life.
- Antimicrobial end caps reinforced for added strength and treated to repel odor-causing bacteria and mold, helping to keep the filter cleaner between uses.
- Salt and chlorine resistance formula resists deterioration in challenging water chemistry, making it a reliable choice for salt pools and high-chlorine environments.
Installation and practicality you’ll notice
- End caps with integrated fittings are molded-in for simple installation and removal, eliminating the need for PAD adapters that can restrict flow.
- Embossed part numbers make re-orders quick and accurate, so you can stock the right replacement without guesswork.
