During program 2, the dry stage begins after the steam exhaust stage,
The exhaust valve is open, while the chamber is heated, which allows evacuation of
water vapors and humidity from the chamber.
For models EA or EKA, an air compressor which works during the dry stage pushes
hot air which flows through a 0.2 yu filter enters the chamber and escapes through the
opposite end exhaling the water vapors and improving drying of the sterilized
material.
