The FP-4040-XLP is a cutting-edge extra low pressure reverse osmosis membrane element designed for maximum energy efficiency. Operating at just 100 PSI (6.9 bar) — significantly lower than standard 150-225 PSI membranes — this 4040 element achieves a 30-50% reduction in pump energy consumption while delivering 2400 GPD of high-quality permeate water.

• Ultra-Low Operating Pressure: Rated at only 100 PSI, this XLP membrane dramatically reduces electricity costs in continuous operation, making it the most economical choice for brackish water treatment systems running 24/7.
• Aromatic Polyamide TFC Technology: Advanced thin-film composite membrane with aromatic polyamide active layer provides superior salt rejection (99.1%) at low pressure while maintaining excellent chlorine tolerance.
• 2400 GPD High Output: Despite the low pressure operation, achieves an industry-leading 2400 GPD permeate flow rate, comparable to standard 150 PSI membranes in the same 4040 form factor.
• Standard 4040 Format: Compatible with all standard 4-inch membrane pressure vessels, enabling seamless retrofit into existing RO systems without hardware modification.
• Extended Membrane Life: Low pressure operation reduces mechanical stress on the membrane surface, minimizing compaction and extending service life beyond conventional membranes.

Perfect for small to medium commercial and industrial RO systems where energy costs are a primary concern: hotel and resort water purification, bottled water production, food and beverage processing, pharmaceutical water pretreatment, and community-scale drinking water systems.
