Product Q&A

Q:Can I replace a 4040 membrane from another brand with yours?

Yes, as long as the model number is the same, it is compatible.

Q:What's the difference between the 4021, 4040 and 8040 models?

The three models have different sizes. You can find the size diagram on the product details page.

Q:How long is the service life of the membrane?

There is no fixed service life for the membrane. Generally, it lasts 1-2 years. The actual service life depends on factors like raw water quality, water consumption, the ratio of pure water to wastewater of the equipment, pre-filter media, and the operating pressure of the equipment all of which affect the lifespan of the RO membrane.

Q:What's the difference between models 21 and 31?

Model 21 has a slightly higher water production rate than Model 31. Model 31 has a slightly better salt rejection rate than Model 21.

Q:What's the difference between ULP and LP?

ULP is Vontron's low-pressure reverse osmosis membrane, with an operating pressure of 6-8 bar. LP is Huitong's high-pressure reverse osmosis membrane, with an operating pressure of 15 bar. Please check the required product model carefully before purchasing.
