1812 100 GPD Superflow – High‑Efficiency RO Membrane Element

The 1812 100 GPD Superflow offers a powerful reverse‑osmosis solution for both residential and light‑commercial applications. Rated for approximately 100 gallons per day (~380 litres per day), this element is designed to work with low‑salinity feed water and standard 1812 housings. According to the “Superflow” spec sheet:

• Rated flow: 100 GPD (~380 L/day)
• Ideal for low TDS feed (< 500 ppm)
• Testing conditions: 60 psi, 25 °C, 250 ppm NaCl solution

Key Specifications

• Model size: 1812 (1.8″ x 12″) housing compatible.
• Rated output: 100 GPD (~380 L/day)
• Typical rejection: ~93‑97% depending on conditions.
• Maximum operating temperature: 45 °C (113 °F)
• Maximum pressure: ~300 psi (21 bar) or similar for “Superflow” versions.
• Free chlorine tolerance: Generally <0.1 ppm—chlorine needs to be removed before the membrane.
• Flow rate note: Actual daily output will vary with feed pressure, temperature, and TDS.

Why Choose the 1812 100 GPD Superflow

This membrane gives you high reliability in a compact size. Since it fits standard 1812 housings, upgrading is simple. Moreover, its “Superflow” variant offers robust capacity for domestic or light‐commercial use. Because it works best with low‑salinity water and requires proper pre‑filtration (sediment, carbon), you’ll get longer service life and consistent output.

Installation & Maintenance Tips

• Ensure your housing is rated for the pressures and size of the 1812 element.
• Pre‑filter feed water: sediment and carbon filters help protect the membrane.
• Remove all free chlorine before membrane feed to avoid damage.
• Install the element according to the flow direction; check for O‑ring seals and leaks.
• After installation, flush the system and check the permeate TDS.
• Monitor output: if flow drops significantly or rejection falls, consider replacing the membrane.
• Replace in accordance with water quality, usage, and manufacturer recommendations.

Applications

• Under‑sink RO systems for households
• Small water‑bar or coffee‑station RO systems
• Light commercial RO setups (offices, clinics) with feed water < 500 ppm TDS
• Use as a replacement element in standard 1812 housings
