-The cold-rolled steel shell is used, and the surface is treated by
electrostatic spraying
-DC
motor, quiet, longer service life
-No
working medium (no oil), no pollution, providing a clean vacuum environment
-Non
friction membrane motion is adopted, which does not generate heat, has no friction
loss, and extends the working life
-It
is small in size, light in weight, easy to move, saves laboratory space, and is
convenient for repair and maintenance.
