™ThePurgAirAdvantage –AnAirFree System.

Benefits• Air-free water flow means enhanced systems operations and reduced costs• Internal diverter effectively separates air from heating and cooling systems.

The result: better performance and lower operating costs• Permits quick venting of air at start-up• Reduces service costs due to air-bound piping• Extends the life of your system by reducing corrosion and erosion• Improves heat transfer efficiency in boilers, fan coils, chillers, etc.• Reduces the overall energy costs of your system• Optimizes pump performance

ApplicationsPurgAir Air Separators should be installed at the highest temperature and the lowest pres-sure points in the system. When this is not possible, the best location is at the point ofhighest temperature. Ideally, a separator should be located on the outlet side of the boiler,and the suction side of the pump.

cost-effective means for

separation of air in a hydronic

system. The Purgair are fitted

with air vent tapping and drain

connection tapping. Purgair’s

rugged construction makes it

suitable for pipe line mounting.

Standard pressure ratings of

150 psi. Available with 150 lb.

plate steel flanges, butt weld

ends and groove ends.

We 100% pressure test every

PurgAir to assure trouble-free
