GoldTop™—Universal Air Vent for Residential and Commercial
Heating and Cooling Systems.
Installers, wholesalers and OEMs can now stock one vent for all
their venting needs between 1 and 150 psi systems and obtain the
highest venting performance. Honeywell 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. Honeywell's
revolutionary patented fulcrum design offers a venting rate of 3-4
times that of other products. It works when others stop venting at
higher pressures. The GoldTop offers convenient, one-fits-all
concept and is competitively priced.
