Ensure full heating performance: Now vent water-bearing heating systems automatically and continuously, including boilers, underfloor heating manifolds, and much more. Your radiator is only fully functional without air in the pipes!

Simple operating principle: A displacement disc in the valve allows air and gases to escape when dry. It immediately seals as soon as the air is out and the disc comes into contact with water.

• Radiator air vents in a double pack: always ensure optimum radiator operation.

• Automatic venting by source disc: allows air to escape only in dry state, stops on contact with water.

• Manual quick venting possible.

• Reliable and durable construction.

• Versatile use in water-bearing systems, such as radiator boilers, underfloor heating manifolds, etc.

• For 1/2" connections.

• Self-sealing thread with O-ring.

• Integrated automatic check: valve change without water loss.

• Set of 2 bleeders including German instructions.
