Welch Direct-Drive High Vacuum Pump 8907A


The Welch Direct-Drive High Vacuum Pump 8907A is a compact high vacuum pump ideal for use with the Shel Lab Model 1445 Series 1.7 cubic foot capacity vacuum oven.

For many applications, Welch Dry Vacuum Pumps will provide drying speeds equal to those of traditional, oil-seal pumps.  This means you can upgrade to a cleaner vacuum pump that is easier to maintain.

Suitable samples include: Foods (Nuts, Cheeses, Fruits, etc), Cosmetics, wet or surface-coated samples needing moisture dryoff, chemicals drying, solvent evaporation, and many others. If your samples can be processed at 3 torr – 10 torr pressure levels, a dry pump will work well in 0.67 cubic foot, 1.7 cubic foot, and even 4.5 cubic foot capacity Shel-Lab Vacuum Ovens.

For electronic component bakeout, curing, or other samples requiring pressures of 1-3 torr, Welch Chemstar, DuoSeal (Belt Drive) and Direct Drive Oil-Seal High Vacuum Pumps are excellent choices for all size vacuum ovens.
