Incubator

An incubator including:

• a housing defining a chamber;
• a pump for introducing air into the chamber through an air inlet;
• a first air outlet for discharging air from the chamber, the first air outlet being spaced from the air inlet;
• a stack of operatively vertically spaced first trays disposed within the chamber, between the air inlet and the first air outlet;
• and
• a first means for tilting the stack of first trays on a plane substantially perpendicular to the direction of operative airflow from the air inlet to the first air outlet;
• a stack of operatively vertically spaced first deflectors are disposed operatively upstream of the first trays for dividing the airflow from the air inlet to the first air outlet into streams of airflow directed over the first trays;
• and
• the incubator further includes a second means for tilting the first deflectors on a plane substantially perpendicular to the direction of operative airflow from the air inlet to the first air outlet to align the first deflectors with the first trays, and
• wherein the first tilting means is coupled to the second tilting means to synchronise tilting of the first deflectors with tilting of the first trays.
