A deaerator comprising:

• a detachable hollow body comprising:
• a lower part of a cup-shaped body with an inlet opening suitable for connection to a hydraulic manifold;
• an upper part of a cup-shaped body provided with a vent opening, said upper part being configured to be stabilized on said lower part with means of fixing, so as to define a deaeration chamber inside said hollow body;
• a float assembly comprising a float element sliding in said deaeration chamber, said float assembly further comprising a drive mechanism;
• and
• a vent valve stabilized on said upper part, said valve being configured to be operated by said drive mechanism;
• and
• a shutter extending through said inlet opening of the lower part;
• and
• an elastic element to hold the shutter in a raised position from a bottom of the lower part of the hollow body;
• wherein said shutter comprises a shaped rod and a head, the shaped rod configured to allow the passage of liquid through the inlet opening, and the head being arranged between an inner end of the lower part of said hollow body;
• wherein the elastic element pushes between the head of the shutter and the bottom of the lower part of said hollow body;
• and
• wherein said shutter includes a collar formed on said shaped rod, the collar configured to block the passage of liquid through the inlet opening when the upper part is in the raised position and detached from the lower part of the hollow body.
