Hydron RO Element 4"x40"

The HLE-4040 is a polyamide compound RO membrane built for window cleaners and solar panel cleaners who want to get more life out of their DI resin. By purifying incoming water up to 98% before it reaches the final DI stage, the membrane leaves the resin with fewer dissolved solids to remove, which can mean fewer resin changes and refills. The tradeoff is pressure; the higher rejection rate requires more pressure to keep water moving through the RO. For that reason, a pump is highly recommended when running this membrane. It is a good fit for RO/DI setups already running a pump, or for window and solar cleaners looking to get longer life out of their DI resin between refills.

Fits any 4"x40" RO housing.

Key Features:

• Up to 98% purification before water reaches the DI resin stage
