PRODUCT FEATURES:

Double the protection: Captures two forms of debris that can damage or shorten the life of heat exchangers, circulators, valves and polymers: ferrous debris such as magnetite, and non-ferrous debris such as copper shavings, solder, lime-scale fragments, silica and pipe compound.

Unique dual magnetic fields: Two powerful neodymium rare-earth magnetic fields attract and capture ferrous oxide impurities and allow simple blowdown - no disassembly required

Unique dual magnetic fields: Two powerful neodymium rare-earth magnetic fields attract and capture ferrous oxide impurities and allow simple blowdown - no disassembly required

Fast and easy clean hands purging: Pull out the magnetic pull rod from drywell on top, unclip the External barrel magnetic collar and open the purge valve to simply release the captured magnetic impurities and purge all dirt.

Caleffi 551004A Automatic Air Vent High Performance 1/2" NPT
DISCALAIR automatic air vents release air that forms in the hydraulic circuits of heating and air conditioning systems, with pressures to 150 psi. The venting air discharge capacity is very high, capable of discharging over 4 standard cubic feet per minute (SCFM). The circulation of fully de-aerated water or glycol-water fluids enables the equipment to operate under optimum conditions, free from noise, corrosion, localized overheating or mechanical damage.

Caleffi 551028A Air Separator 1" Sweat DISCAL
The DISCAL air separator is used to continuously remove the air contained in the hydronic circuits of heating and cooling systems. The air discharge capacity of these devices is very high. They are capable of removing automatically all the air present in the system down to micro-bubble level. The circulation of fully de-aerated water enables the equipment to operate under optimum conditions, free from any noise, corrosion, localized overheating or mechanical damage. Micro-bubbles, fusing with each other, increase in volume (get larger) until they become large enough to rise to the top where they are automatically released.

Series DuoVent High Capacity Air Vents with Manual Vent Feature are used in commercial and residential hydronic heating applications to provide automatic air venting for hot or cold water distribution systems. It consists of a brass body construction with female NPT connection, brass cover, air vent with silicone rubber seal, shutter, polyethylene float with valve plug, automatic vent with black cap, and manual vent with red cap. Series DuoVent has a high capacity and high temperature rating and is ideal for use with glycol systems or for use as an anti-vacuum device. Can be disassembled for inspection and cleaning.

• Air vent with silicone rubber seal
• Impurities do not usually affect function as maximum float line of water is always lower than the valve seal
• Float is high temperature resistant polyethylene
• Suitable for use with glycol systems
• With manual vent feature

The HAV valve utilizes moisture retaining discs within the body which vary in volume when they change from a wet to a dry condition. As the discs dry, they allow air to escape from the system and when wet, provide a positive shut-off.

• Automatic or manual operation
• Quick venting design
• Positive shut-off ball check
• Heat resistant hand wheel
• Simple two piece construction
• Non adjustable
• Straight mount
• Straight body style
