AOS FS-TFC XLE-4021 ULP commercial reverse osmosis membrane. 1000 gallons per day membrane, suitable for aquatics and pole window cleaning.
The AOS XLE-4021 reverse osmosis membrane element is made from the highest quality membrane material manufactured by Toray. This is ideal for use with our own GRP fibreglass, stainless steel or champ 21" commercial RO housings. Designed and manufactured using Toray advanced polymer membrane technology providing some of the industry's most reliable and best performing reverse osmosis elements. Toray are a leading Japanese reverse osmosis membrane manufacturer.
These membranes are manufactured in China by a wholly owned American company that has recently received NSF accreditation across all its products. NSF is the most respected highest international standard. This company is the largest supplier of water products in China. We are proud to tell you these are assembled to the highest standard in China.
XLE-4021 = 4,900 litres (1,079 uk/gallons) per day, at a pressure of 100 psi. This membrane will provide the equivalent out put to an HF-4 membrane and is cheaper. This is under optimum output conditions.
Unlike many other companies, we would like to provide information as to reasonable expectations. Fact: unless you input water is heated to 24°c, and pumped with a pressure of 100 psi, and other water factors you won't achieve this.
UK water temperature is around 12°c, and if you have a pressure of around 55 psi, you will approximately achieve in excess of 1 litre per minute (over 60 litres hour) that is around 1,400 litres per day. If you increase your pressure you can expect a higher output. We assemble systems many times every week and this is what we achieve straight from our pre-filters connected to the water mains when we test systems.
If you are going to pump your water, please ensure that your pump has sufficient water flow and pressure. Beware there are many "Water-movers"; low wattage, low pressure, high volume pumps. You need a pump that will provide around 2.5 to 3.0 litres per minute, at a pressure of 80 to 100 psi constantly.
