For decades Fischer Technical has produced the powerful High-Vacuum 3CFM pump which comes on its own or with a 0-30.00″ Hg Gauge. These are powerful instruments, able to run continuously for long periods of time and capable of producing a near perfect vacuum in most cases.
We’ve carried these units for almost as long as we have been open. A popular set is the Vacuum Experimental Kit which is used by many educational institutions.
These pumps are designed to pump 3 cubic feet per minute (3 CFM) which is pretty good, but could be better. That is why Fischer has recently introduced higher-powered models that can pump much more than their classic model.
So the appearance is the same (Except for the ‘LAV-3″ on the front sticker, but the new units are much more powerful:
Fischer Technical 10 Cubic Feet Per Minute Pump without gauge or with a 0-30″ Hg gauge
These new pumps can fill the need for faster pump down and can handle larger gas loads. All can get as close to vacuum as you could want (better than 28″ Hg ). They can be used for vacuum casting, vacuum ovens, dessicators, impregnation. They are ideal for a lab’s vacuum needs.
Fischer Technical Vacuums are must more affordable than the competition: Manufacturers like Welch, Cenco & Leybold. Their comparable models can cost 4-10x as much as the Fischer line.
