WaterFed abc Reverse Osmosis Filter 4″ x 21″

Reverse osmosis filter waterfed replacement cartridges are the engine of every pure water system, and this 4 × 21-inch module is purpose-built for IPC units. By renewing your membrane with a fresh reverse osmosis filter waterfed professionals can restore peak flow, lower TDS, and maintain spotless window cleaning results.

Manufactured to exact ABC specifications, the high-rejection membrane produces up to 100,000 gallons at 100 TDS before needing service, giving commercial crews months of consistent production. The compact 21-inch length slides directly into IPC housings without modification, sealing leak-free with factory end caps.

• 4 × 21″ size – direct retrofit for IPC RO stages
• High rejection rate for ultra-low conductivity pure water
• Engineered for continuous professional window cleaning duty
• Rapid install – swap membranes in minutes and get back on glass

Keep your waterfed workflow efficient, reduce DI resin consumption, and deliver crystal-clear results on every pane by replacing membranes at the first sign of slowed production.
