Vacuum Pump Requirements
The user must provide a vacuum pump. 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
Triad 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 dry system. The higher
the pressure is set, the more likely it is that oil mist will be exhausted.
Vacuum pumps should be equipped with a reverse IEC plug. This will allow
the vacuum pump to be plugged into the receptacle on the back panel of the
Freeze Dry System. Refer to Appendix D: Triad Freeze Dry System
Accessories for vacuum pumps available from Labconco.
