The DISCAL® air separator uses a coalescing element that consists of an element of concentric diamond pattern mesh surfaces. This element creates the whirling movement required to facilitate the release of micro-bubbles and their adhesion to these surfaces. The bubbles, fusing with each other, increase in volume until the buoyancy force overcomes the adhesion force to the surface. They rise to the top of the unit from where they are released through a float-operated automatic air release valve.

  • Features
  • Product Videos
  • 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 the micro-bubble level
  • The circulation of fully de-aerated water enables the equipment to operate under optimum conditions, free from noise, corrosion, localized 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
  • Stainless steel float guide pin and linkage
  • Glass reinforced nylon internal element
  • Air separator with automatic 1/2 in check valve (Code 561402A) to mount to expansion tank on bottom thread
  • Up to 100% removal air separation efficiency
