1.5 cubic foot Zeolite backwashing filter with Fleck 5600 SXT valve.
High purity natural zeolite is an excellent sediment filtration media. It has the advantages of high flow rate vs. low backwash requirement. The 10" filter requires about 7 gallons-per-minute backwash capacity, but supports a service rate of 7 to 10 gallons per minute. It has a nominal filtration rating of 5 microns — better than Filter Ag or Multi-Media.
