A deaerator is a totally compact sanitary device designed for the removal of air or other occluded gases from any type of liquid or paste, by means of vacuum.

The operating principle comprises the formation of a fine layer of product inside a vacuum chamber, depending on the viscosity, speed and design of the distributor plate. As a result of the vacuum effect, the air bubbles are burst and the deaerated product is discharged through the lower part by means of a positive displacement helicoidal pump.

Numerous processes including the manufacture of food products, cosmetics and chemicals amongst others, need to avoid air oxidation to ensure a correct preservation or application. End products can be mentioned, such as sauces, fruit pulp, cosmetic creams, syrups, PVC dispersions, lubricants, car polish, shower gels, paraffin and penicillin emulsions, ice creams, adhesives, etc.

Production capacities range from 20 to 5000 kg/h in continuous operation.
