HF-04 Capsule Membrane 80 GPD

Water entering the membrane spiral under pressure flows over the surface of the semi-permeable membrane; only water molecules pass through its pores to the permeate outlet. The rejected substances flow off the surface and leave through the concentrate outlet to the drain.

Features

Capsule design without a membrane housing
80 GPD (299 L/day) capacity, 97.5 % salt rejection
Quick membrane change without opening a housing
Sealed housing; no contact with the membrane at replacement

Applications

HF series reverse osmosis units
Compact under-sink RO systems
Service and membrane replacement

Stock Code	Model	Capacity (GPD)	Capacity (L/day)	Salt Rejection (%)
6-25-HF04	HF-04 Capsule Membrane	80	299	97.5

Inlet at the top end; permeate and concentrate outlets at the bottom end (see drawing). Sealed (welded) capsule housing; the membrane cannot be opened and is replaced as a unit. Capacity and salt rejection are values under test conditions; actual production depends on water temperature, pressure and TDS.

Operating Conditions

Test pressure: 4.1 bar
Test concentration: 250 ppm NaCl
Test solution pH: 6.5 - 8.5
Test temperature: 25 °C
Chlorine tolerance: 0 ppm

Materials and Construction

Membrane: Spiral-wound RO membrane
Housing: Plastic capsule, welded
Connection: Inlet at one end; permeate and concentrate at the other, 4/6 stems
Use: Disposable, sealed

Shut off the unit's water supply and open the faucet to relieve pressure.
Disconnect the tubing of the used membrane from the quick fittings.
Fit the new membrane; connect the feed, permeate and concentrate tubing to the correct ends.
Open the water supply and discard the water produced in the first 20 - 30 minutes. Mark the change month on the label.

The membrane's chlorine tolerance is 0 ppm; always use it with a carbon pre-filter and change the pre-filters regularly. Do not use with water that is microbiologically unsafe or of unknown quality without disinfection at the inlet or outlet of the system.
