THE ULTIMATE IN DISTRIBUTION EFFICIENCY
AIR IN SYSTEM WATER
CAUSES MANY PROBLEMS.
Noisy pipes, valves, and other air-related noises are often accepted
as the signs of a functioning system. Excessive pump noise,
cavitation, and cascading in terminal units are considered normal.
But… air in system water can cause corrosion, reduced efficiency,
poorly heated or inadequately cooled rooms, accelerated component
wear and on-going complaints.
There is a device that will keep your system free of air … permanently.
Less maintenance, quiet operation, fewer costs!
The name:
SPIROVENT
Unlike conventional air eliminators or air scoops, the Spirovent
completely eliminates 100% of the free air, 100% of the entrained air,
and up to 99.6% of the dissolved air in the system. Consisting of
woven copper wire soldered to a copper tube, the patented
Spirotube® creates a low velocity area in the Spirovent that scrubs
the bubbles from the water. The air bubbles rise and collect in the air
chamber before they are vented from the system via an integral
automatic valve. Air problems become a thing of the past.
INSTALL THE SPIROVENT FOR
OPTIMUM PERFORMANCE
Ideal placement of the Spirovent Junior is based on microbubble
separation and Henry’s Law*. Simply put, Henry’s Law states that air is
released from water as the temperature increases or the pressure
decreases. In hydronic heating systems, the Spirovent should be
installed in the boiler supply line where the temperature is highest.
Should the circulator be located on the supply line as well, the
Spirovent should be installed between the boiler and the circulator
where pressure is also the lowest.
ADVANTAGES TO THE
INSTALLER AND END-USER
●
Maintenance free.
●
No venting required.
●
Vent head is designed to stay dry. Dirt and leak resistant.
●
1
⁄2” male thread port for pressure testing or remote venting of
unwanted gases.
●
Quiet operation.
●
Increased component life.
●
Reduced oxygen-based corrosion and pump cavitation.
THE KEY DIFFERENCE
The Spirotube is the core of the Spirovent. It allows the Spirovent
to scrub out 100% of the free air, 100% of the entrained air, and
up to 99.6% of the dissolved air in the system. Even the smallest
microbubbles coalesce and rise. Air is eliminated, component life
and heat transfer abilities are increased; oxygen-based corrosion
and pump cavitation are reduced; and annoying gurgling, cascading,
and other air-related system noises are eliminated.

q
Unique valve mechanism is
guaranteed not to leak and cannot be
shut off. Standard thread for vent pipe
connection or pressure testing.
w
Specially constructed air chamber to
protect the valve mechanism from
dirt. Sufficient volume to handle
pressure fluctuations.
e
Solid brass construction for extended
service life.
r
The unique Spirotube is the core of
the Spirovent. Designed to trap even
the smallest microbubbles, yet it
offers little resistance to flow.
