Max Water XLP-4040 RO Membrane | 2300 GPD, 4-inch x 40-inch | Dow Filmtec XLE-4040 / HF4-4040 Compatible

Overview

Meet the Max Water XLP-4040 4-inch by 40-inch RO membrane, a high-capacity solution built for commercial, industrial, and agricultural water purification. This membrane balances strong flow with robust impurity rejection across a range of water chemistries, helping you pursue dependable filtration performance.

Performance highlights include up to 2300 gallons per day, a 99.2% impurity rejection rate, and an operating window near 100 psi with a practical range of 80-150 psi. It is designed for seamless integration with Dow Filmtec XLE-4040 and HF4-4040 modules, enabling straightforward upgrades or retrofits to existing systems.

The membrane uses a 0.0001 micron TFC layer to filter a wide spectrum of contaminants, including heavy metals, organic compounds, and dissolved minerals. It’s important to note that the XLP-4040 is not intended for direct whole-house filtration; proper system design and pretreatment are essential to match water quality and flow demands.

Why choose this membrane?

Durability and safety are at the core. The XLP-4040 ships dry in a sealed package to preserve performance, and the build employs BPA-free components to align with common filtration safety expectations.

• High flow capacity supports larger production needs without sacrificing purity
• Robust impurity rejection provides reliable water quality across applications
• Flexible operating range accommodates different feed water pressures
• Compatibility with Dow Filmtec XLE-4040 and HF4-4040 simplifies retrofits

Product longevity varies with water quality, temperature, and pressure. Expect a useful life of approximately 2 to 3 years under typical conditions, with performance potentially extending or reducing based on pretreatment, cleaning, and maintenance routines.

• Durable, long-lasting construction for steady operation
• BPA-free components reduce exposure to plastic-related concerns
• Designed for a broad set of applications, from commercial to agricultural use
• Shipped dry to preserve membrane integrity during transport and storage

Practical considerations for buyers include compatibility with existing RO systems, water chemistry, and intended use. Before selecting, evaluate your feed water quality (ppm), target purity, and the maximum acceptable production rate to ensure the XLP-4040 meets demand without compromising membrane life.
