1.1 Applicable pump specifications

Model Name Specification Applicable Control unit*1

STP-F2203 series High-flow type SCU-1500/SCU-1400

*1 Applicable control unit: There are different performance specifications between SCU-1500 and SCU-1400.

Refer to Section 1.1.1, "STP pump specifications" for the differences.

Naming convention:

•"C" following a pump model name indicates a corrosion resistant*2 type (e.g. STP-F2203C).

•"CV" indicates an enhanced corrosion resistant type with TMS*3 (e.g. STP-F2203CV).

*2 Corrosion resistant: STP pump with anti-corrosive treatment.

*3 Temperature Management System: TMS unit (optional accessory) maintains the temperature at the base of the

turbomolecular pump by monitoring the temperature with the temperature sensor in the

base of the turbomolecular pump, and performing the TMS valve and base heater

ON/OFF control.

*1 The pressure is applicable under conditions that N2or other similar gas is vacuumed and the backing-pump (pumping

speed: 1,300 L/min) is used. When the gas is exhausted intermittently, the gas more than the maximum gas flow-rate can be

exhausted. Consult Edwards about conditions.

*2 A backup rotational speed is the lowest rotational speed to which the magnetic bearing can be backed up at a power failure.

*3 Time varies depending on the control unit used.
