SynSysCo si the U.S. Distributor and service center for Anest Iwata, L.O.T., and Kashiyama dry vacuum pumps.  Anest Iwata built scroll vacuum pumps are available from 3.8 to 18.4 CFM and have the longest time between scheduled maintenance of any such pump on the market.  The L.O.T. DuraDry series of multi-stage screw pumps are available in sizes from 62 to 2148 CFM and are proven industry leaders in the most aggressive CVD, Metal, and Diffusion pumping applications.  The smaller HD and LD series screw pumps run from 70 to 530 cfm and provide compact. lightweight solutions for Point Of Use applications. Kashiyama's line of NeoDry pumps are an excellent alternative to rotary vane pumps where inert gas or mildly aggressive gasses require oil-free pumping.  They are available sized 250-1200 L/m, and sizes up to 600 L/m do not require cooling water or Nitrogen purge.
