Ordering Notes:
*Manganese greensand filters with tank diameters up to 14" can be regenerated intermittently, and the regeneration feed is included. Filters with tank diameters of 16" and larger require continuous injection of potassium permanganate which will require a tank and feeder. The size of the injection system (sold separately) will depend on the water quality.
** Manganese backwash filters are available with several options of valve voltages. Please add the appropriate voltage code to the end of the model when ordering.
- 110v/60Hz = 116 Example: W-MFI1665G-116
- 220v/60Hz = 216 Example: W-MFI1665G-216
- 220v/50Hz = 215 Example: W-MFI1665G-215
***5 gpm per sq. ft. of media is the best design condition for filtration. For relatively clean water, you may go up to design criteria of 15 gpm per sq. ft. Backwash flow rate based on 25 psi pressure drop.
Skid mounting, control panel and custom sizes and configurations are available upon request. AMI Auto Backwash Carbon Filters are offered standard with new state of the art electronic programmable valves, but may be ordered with electromechanical Fleck valve heads upon request.
