Vacuum Pump Requirements
A vacuum pump must be provided by the user. A vacuum pump with a
displacement of 144 liters per minute and 0.002 mBar ultimate pressure is
adequate for most samples. The inlet fitting on the vacuum pump must be
suitable for 3/4" ID vacuum hose, which is provided with the FreeZone Freeze
Dry System. It is recommended that the vacuum pump is equipped with an
exhaust filter to minimize oil mist exhausting from the vacuum pump. The
operating vacuum level may be set on the freeze dryer system. The higher the
pressure is set, the more likely it is that oil mist will be exhausted.
Vacuum pumps used with 115V models should be equipped with an 115V, 15
Amp NEMA 5-15P plug. Vacuum pumps used with 230V models should be
equipped with a reverse IEC plug. This plug is included with 230V models. This
will allow the vacuum pump to be plugged into the receptacle on the back panel
of the Freeze Dry System. Refer to the User’s Manual for the FreeZone Freeze
Dry System for vacuum pumps available from Labconco.
