Part #: PJR 000 HA
Air eliminator for closed-loop hydronic (boiler) heating system.
The professionals encourage proactive preventative maintenance on all “wearable” parts to keep your hydronic heating system running optimally and thus saving you money! Air trapped in the system causes blockages and inefficient heating zones. Most hydronic heating systems have one but many homeowners don’t realize that the minerals in the fluid clogs the vent eventually. When this happens, the air is unable to be expelled from the system.
New this goes for $70+. Mine works perfectly but since it’s used, I’m selling it for 80% off the price of the new version.
