During filling, maintenance, or through oxygen infiltration, air is introduced into every hydronic heating/cooling system. To function properly, the air must be eliminated and these air eliminators are designed to remove trapped air, micro bubbles and dirt from heating, cooling and domestic water systems. We are your source for air eliminators and many other heating and cooling parts and products.

 |
These float-type automatic air vents are designed to be installed vertically to vent air that is released from the water by being heated. Silicon seals, anti-vibration and anti-rotation features ensure long life and superior venting. |
| Floatvent, Supervent, Maxivent |
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.

| Hygrovent |
HV 190 |
The Sparco Hygrovent is an automatic air vent for hot water and steam systems. Install in baseboards, radiators, convectors and high points in piping systems to remove air. The nickel plated valve has a quick venting design and a positive shut-off ball check.
Note: These units must be installed vertically |
Air Purger
Stamped Sparco or Honeywell on side
Powervent Gold
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. |
