Page 21: Circulation
Installation 3.7.5 Circulation The blower is designed to circulate the Glovebox atmosphere continuously through the purifier column. For optimum performance the blower must run constantly. Turning off the blower results in the atmosphere within the Glovebox degrading as it is not being circulated through the O2 and H2O absorbing materials contained within the purifier column. - Page 22 Installation The blower provided is continuously variable; it can be set at a very low speed if you are handling sensitive crystals or during weighing. It can be set at a maximum to recover quickly from an operator error. We suggest it be set at 50% during normal operation. Blower speed can be changed by pressing the numeric value next to the Change Blower Speed.
