LIGHT COMMERCIAL - ULTRA REVERSE OSMOSIS SYSTEM

This is our most durable reverse osmosis system with low pressure FILMTEC membranes for compact commercial applications. The Light Commercial (LC) models are super quiet and energy saving because they do not need pumps or electricity and are driven by your water pressure alone.

This system is built to last with convenient 20" industrial sized housings and filters to eliminate frequent filter change-outs. We provide unmatchable value in quality, convenience and price in this durable system. This is the best valued commercial RO system if you have good water pressure.

*Please note that this system should not be installed at the main water line as a whole-house water filter.

Trusted Quality in APEC Drinking Water Systems

APEC reverse osmosis systems are engineered for high performance, durability and safety. Constructed of select premium components, our RO systems have been tested to guarantee the highest contaminant removal rates, giving you the purest water possible. We are one of the very few manufacturers who still insist on building, inspecting, and lab testing every system in our US facility. Our stringent QC process eliminates even the slightest component imperfections to guarantee a system that is free from water leaks, bursts and noises.

For over 17 years, APEC has been an industry leading manufacturer who specializes in high performance RO systems. Founded by engineers, our company understands the science behind our business, however through the years we have learned that the true value of our offerings comes from our service and support. As the original manufacturer, we have dedicated a knowledgeable and sincere team that is committed to providing customer satisfaction for the entire lifespan of every system – unparalleled in the industry. 

Every APEC system is built to meet the most demanding applications in water purification -- from drinking water for homes, to purified water for restaurants, healthcare facilities, and research labs. Our durable RO systems are designed to last for decades and will bring many years of enjoyment and good health for you and your family.

Flow Rate with Variable Pressure and Temperature:

When sizing a system, particularly if system output is critical for you, you need to understand that the actual flow rate GPD(Gallons Per Day) of any reverse osmosis system depends on the input water pressure, temperature, and water conditions. The higher your input water pressure and temperature, the higher the pure water output. The industry standard*, which is the same as our standard, is set at 60 psi pressure and 77° F(25° C) temperature.

*Please note that this standard is not necessarily followed by all vendors. We have seen other RO systems claiming 100 GPD at 100 psi —very unrealistic input water pressure! So do check on these facts before you make a buying decision.

More on water temperature: While the industry standard temperature is set at 77 °F, we know that not everyone has 77 °F input water. Below is a water temperature compensation chart for you to calculate the nominal GPD of your RO system at different temperatures.

INSTRUCTIONS: find your water temperature and its factor, divide the RO system GPD by that factor, and you will get the temperature-corrected output.
