Honeywell-Sparco Air Vent Model: FV147A Size: 1/4"NPT
Sparco has reinvented the vent! Air vents have been removing air from heating and cooling systems for decades. Some were better than others. Many stopped venting after initial filling. No one has, up to now, been able to design a low cost vent that performs at both low and high pressures. It was always one or the other. Sparco's revolutionary patent pending fulcrum design offers a venting rate of 3-4 times that of other products. It works when others stop venting at higher pressures.
Product Application: Residential or commercial heating an cooling systems including Solar Water Heaters and Solar Collectors.
Product Function: Sparco Air Vent purges and eliiminates air in water lines. Valve should be installed in an upright position at the highest point in the plumbing.
