hello,
I have build a vacuum chamber out of an acrylic cylinder.
I can get down to 50 micron but if I turn off the vacuum motor the chamber does not keep its atmosphere (air getting in)
What i did is add a high quality valve between the chamber and motor. Sunk everything in an oil bath. Turn off the valve and quickly disconnect the hose from the motor vacuum and sink that in the oil bath too.
Now everything is submerge and My sensor indicates that air is coming in ! slowly goes from 50 micron to 600 micron then it stays there
Any thoughts about this would be appreciated??
thanks
ken
