What makes the FC-2972 stand out
- Reinforced center cores: Extruded PVC center cores provide even stress distribution and higher debris loading, helping prevent cartridge collapse under heavy loading and extending time between cleanings.
- Premium filter media: Durable polyester media delivers lasting filtration performance, cleaner water, and easier maintenance over the life of the cartridge.
- Antimicrobial end caps: End caps are reinforced and treated to repel odor-causing bacteria and mold, helping preserve cartridge integrity in salt and high-chlorine environments.
- Wider support bands: Extra-wide bands resist breakage and keep pleats evenly spaced for optimum flow and filtration performance.
- Sharp pleat folds: Innovative synthetic fiber construction prevents bridging, allowing dirt to penetrate deep into the pleats for improved filtration efficiency and easier cleaning.
- End caps with integrated fittings: Molded-in fittings simplify installation and removal, eliminating the need for PAD adapters that can reduce flow and filtration efficiency.
- Embossed part numbers: Easy identification and ordering help you keep your spa/pool running smoothly with the right replacement cartridges.
- Extruded PVC center cores: The strongest design with round holes to distribute stress evenly, reducing the risk of cracks and collapse even under demanding conditions.
