  1. Caleffi Discal Series 551 Air Separators Brass NPT

    Caleffi Discal Series 551 Air Separators Brass NPT

    Air separator with automatic ½" check valve (code 561402A) to mount expansion tank on bottom thread. Brass body. Glass reinforced nylon internal element. Max. working pressure: 150 psi. Working temperature range: 32—250°F.
    In heating and air conditioning control systems, the circulation of water containing impurities may result in rapid wear and damage to components such as pumps and control valves. It also causes blockages in heat exchangers, heating elements and pipes, resulting in lower thermal efficiency within the system. The dirt separator separates off these impurities, which are mainly made up of particles of sand and rust, collecting them in a large collection chamber, from which they can be removed even while the system is in operation. This device is capable of efficiently removing the smallest particles, with low head loss.

  8. Caleffi Discal Series 551 Compact Air Separator 3/4" Sweat

    Caleffi Discal Series 551 Compact Air Separator 3/4" Sweat

    Air separator. Brass body. Stainless steel mesh internal element. ½" NPT bottom thread. Max. working pressure: 150 psi. Working temperature range: 32—250°F.
    Air separators are 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, fuse together, increase in volume until they become large enough to rise to the top where they are automatically released.
