5 STAGE DIRECT FLOW RO SYSTEM

Suitable For Drinking Water

The 5 Stage Direct Flow RO system is a compact solution for producing drinking water quality purified water, measuring just 53cm tall, 43cm wide and 27cm deep. Utilising an integrated 500GPD booster pump the system can run on pressures as low as 1 bar, making this a great choice for direct flow applications, where purified water is required on demand (such as for the cutting of spirits, use with autoclaves, or coffee machines). The visible pressure gauge gives a clear indication of filter lifespan, making this system incredibly easy to operate and maintain.

Why Use A Direct Flow RO System?
This system is a great alternative to buying purified water, offering a short payback time and low maintenance costs. With an adequate flow rate of 78 litres per hour, this RO accommodates many small-batch applications without the use of a water-storage tank which can otherwise take up valuable space. A de-ionising stage can also be added to the outlet of this system, polishing off any remaining TDS to give 0ppm pure water (where high-purity water is required such as for electronics, autoclaves and lead-acid batteries).

How Long Do The Filters Last?
All pre and post-filters should be changed every 6 months based on daily usage. The 500GPD RO membrane needs to be replaced every 2-3 years if you have soft water, or every 1-2 years if you have hard water. For customers in hard water areas, pre-treatment is recommended to improve membrane lifespan and to reduce operating costs.

Why Choose Our 5 Stage Direct Flow RO System?

  • Small footprint with no separate water storage tank
  • Cost effective alternative to buying purified water
  • Suitable for water pressures as low as 1 bar
  • Visible pressure gauge for filter lifespan
  • Easy to operate and maintain

Very pleased with the service. There was an issue with the water softener I ordered initially, but then following communications made the replacement process quite pleasant. Happily recommend this company. Thanks to Becky for working with me. Great follow up support 😊😊😊

First time using this company and product and i wasnt dissappointed. Communication was easy and quick resulted in an easy order and now having fitted the filter i can say its a great product easy to install and appears good quality apart from the four mild steel bracket screws stainless would have been better considering the environment these are fitted. All in all, very pleased and would highly recommend .

Excellent local company and genuinely lovely people to deal with. Really helpful and knowledgeable, with great advice about my water softener and the correct salt to use. They even gave me some resin cleaner at no charge, which was a very kind gesture. Fantastic friendly service and I’ll definitely be returning for my salt in future. Highly recommended.

Excellent service. Product proved my softener was not working as it should. I fully serviced it and cleaned with Resin Clean returned to service and it is now working as designed. Very pleased.

If you're thinking about a water softener then i HIGHLY recommend Ultra Soft Water Softeners Ltd. Great softeners and exceptional customer service. The water softener I bought needed some adjustments with the installation setup where I supported throughout. The customer service is honestly next level. I had countless calls with Becky Gillett, the Sales Manager, over a period of months to get to the bottom of it. She was incredibly patient with me, staying on the phone and doing video calls to walk me through the programming instructions step-by-step while I changed the settings and ensured all was installed correctly. All the staff here have been great, but Becky really stuck with me from start to finish to make sure it was sorted and working well. It runs like a dream now. HIGHLY recommend them!

Easy to order, quick delivery, good communication. Resclean worked a treat; one treatment cycle and soft water is back again from our 12 yr old softener!
