F93 Series Air Volume Controls for Deep Wells
Product/Technical Bulletin
Part No. 24-7664-3000, Rev. A
Issued October 2018
The F93 Series Air Volume Controls for Deep Wells
control the amount of air in the residential water
storage tanks of deep well water systems. Deep wells
are more than 25 ft (7.6 m) deep.
F93 Series Controls automatically maintain air volume
in the storage tanks of deep well water systems by
allowing air to escape from the tank and into the
surrounding room when the water level in the tank
drops (increase of air volume).
F93 deep well controls open the air valve on a fall in
tank water level to bleed excess air from the tank at
pressures up to 100 psig (690 kPa).
The F93H has a minimum pressure release valve to Figure 1: F93B Air Volume Control
avoid lowering tank pressure below 25 psig (172 kPa). for Deep Wells
Use this model on applications where water may be
rapidly drained.
