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.
