Spirovent® Air Eliminator employs a patented Spirotube® coalescing medium that
”scrubs” the air from the system fluid. Simple to install with a straight
in-line design it is available in the Junior Series for residential and light
commercial applications from ¾” to 2” pipe size. Solid brass construction,
integral patented air release mechanism and a 20 year limited warranty.
units are fabricated steel and available from 2” through 36” pipe size and can
handle flows to over 30,000 GPM. Custom fabrication is available for special
project requirements. For large high velocity systems the ”HV” Series is available
specifically for central plants and district systems where large volumes of
water are being distributed.
air/water mixture enters the Spirovent and the Spirotube coalescing medium
combined with a drop in velocity allows the air to break free of the flow path.
All free and entrained air is removed through the integral vent mechanism along
with up to 99.6% of the dissolved air. The need for frequent venting, bleeding
and purging is eliminated along with air related gurgling and waterfall noises
in the piping.
Spirotop® Air Release Valve is essentially the vent head used on all products
through 12”. It has a ½” bottom connection and can be used in places where
other float vents have been used. Carries a 20 year Limited Warranty and is
designed not to leak by means of a dry air chamber.
