Taco In-Line Air Separators (AC / ACF Series)

  • Taco AC/ACF Separators use a large-diameter chamber and internal baffle to reduce fluid velocity and change flow direction, allowing air to rise to the top connection. Captured air can be vented through an automatic air vent or directed to a plain steel expansion tank, depending on the system arrangement.
  • AC models are supplied without a strainer; ACF models include a removable stainless steel strainer for collecting larger particles. Multiple sizes, connections and pressure ratings accommodate different system requirements.
  • Standard connection sizes: 2"–20"; custom sizes up to 36".
  • Body: Carbon steel with exterior red oxide primer.
  • Internal design: Baffle-assisted, low-velocity air separation.
  • Standard working rating: 125 psi at 375°F (approximately 8.6 bar at 191°C).
  • Optional working pressures: 150, 250 or 300 psi (approximately 10.3, 17.2 or 20.7 bar); higher ratings upon request.
  • Connections: Threaded or ANSI flanged, depending on model; grooved options available.
  • ACF strainer: Removable 304 stainless steel, with 3/16" perforations (approximately 4.8 mm).
  • Strainer free area: At least five times the nozzle opening area to limit pressure loss.
  • Service connections: Top air vent/expansion tank connection and bottom blowdown connection.
  • Options: Alternative construction materials and custom sizes or pressure ratings.
  • Helps reduce air locking and maintain system circulation.
  • Supports heat transfer and system efficiency.
  • Helps reduce air-related corrosion, pump damage and operating noise.
  • Large separation chamber limits pressure loss.
  • ACF strainer captures larger debris and is removable for cleaning.
  • Compact construction helps minimise installation space.
  • Hydronic hot water heating systems.
  • Chilled water and cooling systems.
  • Water and water/glycol circuits.
  • Commercial, institutional and industrial installations.
  • Air elimination systems with bladder or diaphragm expansion tanks.
  • Air control systems with plain steel expansion tanks.
  • ASME: Designed, constructed, tested and stamped to Section VIII, Division 1.
  • National Board: Pressure vessel registration.
  • ISO 9001: Manufacturer’s quality management certification.
