M9/M11 Steam Sterilizer Fan System

Fans

The fans reduce heat inside the enclosure by circulating air between the chamber and the cover.

The digital temperature sensor (located on the main PC board) controls the ON/OFF function of the fans.

When the temperature exceeds 45 °C (113 ° F), the fans turn on. When the temperature drops below 41 °C (105.8 °F), the fans turn off.

The fans run regardless of the state of the temperature sensor during the heating phase and then turn off at end of cycle (if no drying, then at end of Venting). Prior to venting, the bottom fans will shut off for a few minutes.

12 VDC is applied to the fans causing the fans to run.

The top fan blows air out of the enclosure. The bottom two fans blow air into the enclosure.
