Does 500 L/h mean 500 litres of storage?
No. L/h describes a production rate; L describes a volume. The latest 500 L/h specification lists a 200 L tank. Tank capacity for the 300 L/h configuration remains to be confirmed. Confirm usable storage separately from production capacity.
Are all pressure figures the same?
No. The 300 L/h configuration has a stated RO operating pressure of 0.6–2.0 MPa. For the 500 L/h configuration, the specified 0.1–0.4 MPa is inlet pressure and 0.2 MPa is supply-pump pressure; neither establishes its RO operating pressure. Its supply-pump flow is 1.5–3 m³/h, separate from RO water production of 500 L/h.
How to choose between 300 and 500 LPH RO systems
Start with daily treated-water demand and available production hours. For example, 3,000 L/day divided by 10 production hours requires an average 300 L/h. This calculation alone does not establish that JFPS-300L is sufficient: peak use, reserve capacity, feed-water conditions and downtime require review.
Request a quotation for the exact model and configuration, including the tank, distribution system, electrical supply and installation scope. Neither nominal output is a guaranteed on-site result.
Why does the older series page show different dimensions?
The series catalogue, July model records and September update describe different source configurations. The current 500 L/h dimensions are 850 × 750 × 1780 mm. Current 300 L/h dimensions and both net weights require confirmation. Do not fill those gaps with earlier catalogue values.
