Filmtec (XLE-2521) Low Energy Membrane 365 GPD 2.5"X21"

The Filmtec XLE-2521 delivers 365 GPD of purified water at the lowest operating pressure in the industry, reducing energy costs and extending component life in small commercial RO systems. This 2.5" x 21" low energy membrane achieves 99.0% salt rejection while operating at pressures lower than standard elements, making it ideal for installations where energy efficiency matters.
SPECIFICATIONS

Filmtec XLE-2521 Technical Details

Model Number XLE-2521
Dimensions 2.5" diameter x 21" length
Permeate Flow Rate 365 GPD (1.38 m³/d)
Active Surface Area 13 ft² (1.2 m²)
Salt Rejection 99.0% stabilized
Operating Pressure 100 psig (6.9 bar) nominal
Test Conditions 500 ppm NaCl, 77°F (25°C), 8% recovery
Flow Variance ±20% per element
INSTALLATION & USE

Installing the XLE-2521 Membrane

  1. Ensure the membrane housing is clean and free of debris before inserting the XLE-2521 element into a compatible 2.5" x 21" pressure vessel.
  2. Install the membrane with the brine seal oriented correctly, ensuring proper seating against the end cap to prevent bypass flow.
  3. Flush the system at low pressure for 30-60 minutes after installation to remove preservatives and allow the membrane to stabilize before bringing to full operating pressure.
  4. Monitor permeate flow and TDS during the first 48 hours of operation, as new membranes typically stabilize within this period.
COMPATIBILITY

System Requirements

The Filmtec XLE-2521 fits standard 2.5" x 21" commercial RO housings and is designed for small commercial systems processing less than one gallon per minute of purified water. This extra low energy element works best with tap water feed sources and is compatible with systems using lower cost pumps and components due to its reduced pressure requirements. Suitable for applications including beverage preparation, light food service, small laboratory use, and other commercial settings requiring consistent high-purity water production.

🔧 The XLE-2521's low energy design means you can often reduce operating pressure by 15-20% compared to standard membranes while maintaining the same permeate flow, which translates to measurable energy savings and longer pump life in continuous-duty commercial installations.
