Lab Exercises on Small Systems
In a refrigeration lab, students evacuate a domestic refrigerator trainer through the Manifold Gauges For Refrigeration Systems, with the yellow hose on the 1/4 in pump inlet. They note how long the compound gauge takes to reach its lowest reading. Then they repeat the job with one of the Fast Vacuum Pumps and compare the two pull-down times.
A standing vacuum check follows, with the manifold valves closed and the gauge watched while the pump stands idle. Teachers also show an oil change. They drain the pump and refill it with Replacement Vacuum Pump Oil, so students can compare cloudy, wet oil with fresh oil.
Frequently Asked Questions
Is 4 CFM enough for my work?
For small systems, yes. It suits domestic refrigerators, water coolers, deep freezers, window and small split air conditioners, and lab trainers. On larger systems it takes much longer, and a higher-flow pump does the job faster.
What does 150 microns mean?
It is the lowest pressure the pump reaches on its own with the inlet closed off. A system reading will sit higher, because hoses, joints and any moisture left in the circuit add load.
Will a standard charging hose fit the inlet?
Yes. The inlet is a 1/4 in port, so any hose with a 1/4 in flare end fits, such as the plain-ended Refrigerant Hose set. For the larger ports on newer split units, fit one of the Hose Adapters at the system end.
How often should the oil be changed?
Look at it after each job. Fresh oil is clear, and once it turns cloudy or milky it holds moisture and the pump will not reach its rated vacuum. Change it then, and always after a wet system.
