What is the minimum flow rate through a TR-140C filter?

For the Pentair Triton C TR140C Sand Filter, the maximum flow rate is specified at 141 gallons per minute (GPM), based on a filtration rate of 20 GPM per square foot over its 7.06 sq. ft. filtration area .While the manufacturer does not explicitly state a minimum flow rate, it's essential to ensure that your pool's circulation system provides sufficient flow to achieve proper turnover and filtration. Typically, a flow rate of 1 to 2 GPM per square foot is considered a reasonable minimum for sand filters, which would correspond to approximately 7 to 14 GPM for the TR140C model.However, operating at such low flow rates may not provide adequate filtration for most pools. Therefore, it's advisable to aim for a flow rate that allows the entire pool volume to be filtered at least once every 8 to 12 hours, depending on usage and environmental factors.To determine the appropriate flow rate for your specific pool, consider factors such as pool volume, pump capacity, and desired turnover time.
