The Agilent Technologies TwisTorr 84 FS is a turbomolecular pump for high and ultra-high vacuum applications. The TwisTorr 84 FS is equipped with new and improved bearings and its TwisTorr drag state technology enables high compression of gases such as Helium and Hydrogen. The TwisTorr 84 FS is designed to pump any type of non corrosive gas and can be used with a smaller backing pump (5 m3/h).
The Agilent Varian TwisTorr 84 FS pumping action is obtained through a high speed turbine (max. 81000 rpm) driven by a high performance 3-phase electric motor. The TwisTorr 84 FS is free of contaminating agents and, therefore, is suitable for applications requiring a "clean" vacuum.
The TwisTorr 84 FS pump consists of a high frequency motor and a high-strength aluminum alloy turbine fitted with 9 bladed stages and 3 TwisTorr drag stages which are in the form of four disks. The turbine rotates counterclockwise when viewed from the high vacuum flange end. The TwisTorr 84 FS rotor is supported by permanently lubricated ceramic ball bearings. The static blades are precisely situated with the help of spacer rings and are made of stainless steel. The TwisTorr stators are in the form of machined disks with parallel spiral pumping channels. During normal operation, the motor is fed with a voltage of 54 Vac three-phase at 1350 Hz.
The Agilent TwisTorr 84 FS turbomolecular pump can be water cooled or air cooled. In order to prevent the pump from overheating, a thermistor sensor is mounted near the upper bearing.
