Gold Top Air Vent
	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 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. The GoldTop is field serviceable, offers convenient, one-fits-all concept and is competitively priced.

Floatvent, Supervent, Maxivent
Floatvent FV 183	Supervent SV 173	Maxivent FV 147/147A
The Sparco Floatvent is an efficient automatic vent with high venting capacity. It removes trapped air that prevents free circulation of liquids and restores maximum performance of the system. Floatvents are used for continuous venting of hot water and chilled water cooling systems. The Floatvent removes air from tanks, radiators, pipelines, radiant panels, unit heaters and systems. The Maxivent features a low profile, fit anywhere solid brass body and cover, and a high temperature polypropylene float. The Supervent has a high venting capacity and incorporates a check valve.

NPT Powervent

During filling, maintenance or through oxygen infiltration, air is introduced into every hydronic heating/cooling system. To function properly, the air must be eliminated. The Sparco Powervent slows the velocity of the water in its enlarged chamber, where the water impacts onto a stainless steel dynamic concentrator. The concentrator merges bubbles and microbubbles, which then float to the top from where they are vented to the outside. The high capacity vent keeps the water level below the venting point for a clean vent nozzle. The GoldTop venting mechanism (patent pending) offers the largest venting rate at pressures up to 150 psi.
