Altecnic Robocal 15mm automatic air vent (502649) removes trapped air from heating and cooling systems via a float mechanism. Compression, vertical-discharge design isolates automatically during filling to prevent water loss, reduce noise and improve performance.

• The range of automatic air vents is operated via a float mechanism and is designed for the removal of air from systems
• Discharge pressure 6 bar
• Small sized valves for tight installations
• Manual cap fitted if required
• Compression or male threads available
• Sizes range from 6.35 mm, 9.525 mm, 12.7 mm or 15 mm compression
• Check valves available
• Operated via a float mechanism to continually remove air from heating and air‑conditioning systems — releases air as the system is filled then automatically isolates to prevent water loss and wastage, reducing noise and improving control‑valve accuracy and overall system performance.
• Compression end provides a secure, leak-resistant connection to copper pipework.
• Optional manual cap and check-valve variants available to assist maintenance and prevent backflow.
