STP-iXA3306C ISO250F

YT820Z020 - STP-iXA3306C ISO250F


The STP-iXA3306 series magnetically levitated turbomolecular pump provides industry-leading performance and incorporates a small power supply into the onboard control unit – the latest technology of the well-established STPiXA3305 series.
The height of the pump is equal to the STP-XA2703/XA3203 and is also equal to the height of the STP-iXA3305 series without its power supply (iPS-1200). This fully integrated product offers easy installation and a small footprint as an all-in-one solution for all application tools.
