Pure Water Power 272-21-04 Double RO/DI System – 1.75 GPM, No Pump Required

The Pure Water Power 272-21-04 Double RO/DI System produces 1 to 1.75 gallons per minute of 0 TDS pure water at standard 50 PSI municipal water pressure — without a booster pump. Two 40-inch RO membranes in parallel double the flow rate of a single-membrane system, making this unit capable of running two water fed poles simultaneously. The powder-coated steel frame with flat-free wheels is made in the USA.

Where Window Cleaning Companies Use the 272-21-04

Window cleaning companies that clean multi-story commercial buildings use the 272-21-04 when their tap water pressure is at or above 50 PSI — the case in most municipal water systems — and need 1+ GPM flow rate without adding a booster pump and its associated power requirements. The dual membrane design supports two-operator teams working with two poles from a single system. The system can be positioned freestanding on the job site or laid flat for transport in a cargo van. The flat-free wheels eliminate flat tire downtime that pneumatic wheels suffer on job sites with debris.

Four-Stage Filtration and TDS Reduction

The 272-21-04 runs tap water through four stages: 10-inch sediment filter (removes particles), 10-inch carbon filter (removes chlorine and organics), dual 40-inch RO membranes (removes dissolved minerals, heavy metals, and most contaminants), and 10-inch DI resin cartridge (polishes to 0 TDS). Water at 0 TDS evaporates from glass without leaving mineral spots or streaks — eliminating the need for squeegee work after rinsing.

Frequently Asked Questions

Does the 272-21-04 require a booster pump?
No. The Double RO/DI system produces 1 to 1.75 GPM at standard 50 PSI municipal water pressure without a booster pump. If your water pressure is below 40 PSI, a booster pump may be necessary to achieve full flow rate.
Can the 272-21-04 supply two water fed poles simultaneously?
Yes. The dual 40-inch RO membranes produce enough flow for two-pole operation at typical water pressure. Flow split between two poles will be approximately 0.5 to 0.875 GPM per pole at 50 PSI input.
How often do the filters need replacement?
Filter life depends on input water TDS, water usage volume, and water temperature. The sediment and carbon pre-filters typically need replacement every 6-12 months with regular professional use. DI resin needs replacement when output TDS rises above 0. RO membranes typically last 2-5 years. The included TDS meter monitors output quality.
Is the 272-21-04 made in the USA?
Yes. The PWP Double RO/DI system is made in the USA, using a powder-coated steel frame with domestic-sourced components.
Can the system be used vertically and horizontally?
Yes. The 272-21-04 can be positioned upright (standard operation) or laid flat for transport in a cargo van or truck bed. The fittings and membranes function in both orientations.
