Design Specifications

Designed for gravity-fed water that has been filtered. The feeder is installed prior to a storage tank. The water to be treated enters in the 4? PVC inlet and exits through a 4? PVC outlet. The water erodes the tablets as it passes through. The LF Series have 1, 2, 3, or 4 feeder tubes for holding chlorine tablets. The LF 1000 holds 20 tablets, LF 2000 holds 40 tablets, LF 3000 holds 60 tablets, and LF 4000 holds 80 tablets. Typically a bypass arrangement is used so 10-30% of the total flow passes through the tablet feeder to prevent over-chlorination.
