40" Axeon HF4-4040 extra-low pressure Reverse Osmosis membrane

The Axeon HF4-4040 is a commercial reverse osmosis (RO) membrane known for its extra-low energy consumption and high performance. It is a thin-film composite polyamide membrane element designed for tap water applications that require a balance of high water production and low operating costs. 

Key performance specifications

Permeate flow rate: Up to 2,500 gallons per day (GPD), or 9.46 m³/day.

Average salt rejection: A nominal 99% rejection rate, which ensures high-quality purified water.

Applied pressure: Operates efficiently at a low applied pressure of 100 psi (6.89 bar), which results in significant energy savings compared to standard membranes.

Dimensions: It is an industry-standard size of 4 inches by 40 inches and features a protective ABS shell.

Operating temperature: A maximum continuous operating temperature of 113°F (45°C).

pH range: A continuous operating pH range of 2–11, with a short-term cleaning range of 1–13. 

Features and benefits

Energy efficient: The low operating pressure of 100 psi significantly reduces the energy required for the RO process, lowering operating costs.

Consistent performance: Built with advanced membrane technology and manufacturing processes to ensure high-quality and reliable results.

Quality tested: Every membrane is 100% vacuum integrity tested to ensure consistent and dependable performance.

Long shelf life: Shipped dry for easier handling and an indefinite shelf life.

Durable: A hard ABS shell provides added structural integrity and protection during shipping, installation, and operation. 

Common applications

The Axeon HF4-4040 membrane is used in a variety of commercial and industrial settings, including: 

Commercial water treatment: For hotels, restaurants, and other businesses that require a consistent supply of purified water.

Industrial water purification: Used in manufacturing and processing plants.

Municipal water systems: Deployed in smaller public water purification systems.

Window cleaning systems: Used for producing pure water for window cleaning.

Food and beverage: Provides high-purity water for food and beverage production.

Pharmaceutical production: Suitable for use in pharmaceutical manufacturing processes.

HF4 vs. HF5 series

Axeon also offers the HF5 series, which provides even greater energy savings, though at a slightly lower salt rejection rate:

Operating pressure: HF4 operates at 100 psi, while the HF5 operates at an ultra-low pressure of 80 psi.

Salt rejection: The HF4 has a nominal salt rejection of 99%, compared to the HF5's 98.5%.

Cold water performance: The HF5 series is particularly suited for applications with colder water temperatures, which typically reduce RO production.
