SUEZ AK4021TF; 4" X 21" 1050 GPD TFC Replacement Reverse Osmosis Membrane - (Product flow @ 107 PSI) (Veolia)
AK4021TF 4" × 21" Low Pressure Thin-Film Composite Membrane
The SUEZ AK4021TF (formerly GE Desal) is a commercial thin-film composite reverse osmosis element engineered for brackish and tap water applications where high rejection is needed at lower operating pressures. Rated at 1050 GPD at 107 PSI, this 4-inch by 21-inch element features a tape outer wrap and 28-mil feed spacers with male end connections, delivering consistent performance in light commercial and high-demand residential installations.
Engineered for Low-Pressure Efficiency
High Flux TFC Membrane
Thin-film composite construction with high permeate flow and excellent salt rejection for consistent water quality in brackish water systems
Low Operating Pressure
Optimized for operation at 100 PSI and above, reducing energy costs and extending pump service life in commercial installations
Standard 4" × 21" Footprint
Drop-in replacement for commercial housings using male end adapters, compatible with legacy GE Desal and FilmTec-style systems
Tape Wrap & Dry Storage
Factory tape-wrapped with 28-mil feed spacers, shipped dry to ensure long shelf life and reliable startup performance
Commercial Grade
Designed for continuous duty in restaurants, labs, small industrial applications, and whole-building water treatment
High NaCl Rejection
A-Series thin-film chemistry delivers dependable salt removal for brackish water and tap water desalination applications
Replacement for GE Desal & Legacy Systems
The SUEZ AK4021TF is compatible with GE Desal part number 1206812 and other AK-Series low-energy RO elements. Designed for use in commercial 4-inch housings with male end adapters, this membrane fits systems from Veolia, FilmTec-compatible platforms, and other standard brackish water reverse osmosis configurations. Ideal for tap water purification, light brackish water desalination, restaurants, coffee shops, laboratories, and whole-building commercial installations requiring reliable low-pressure operation.
SUEZ (Veolia Water Technologies) AK-Series membranes are specified by engineers worldwide for dependable, cost-effective brackish water treatment.
