Fast Vacuum Pumps Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-12759
Jlab Export is a leading Fast Vacuum Pumps Manufacturer,and suppliers in India
This two-stage vacuum pump pulls air and moisture out of a refrigeration or air-conditioning circuit before it is charged. It moves 15 CFM and reaches 15 microns or better. It runs on 220–240 V, 50 Hz with a DC motor, and has a solenoid or check valve and a built-in vacuum gauge.

Evacuation Practicals for Students
Before evacuation, students pressure test a split AC trainer with the Nitrogen Pressure Test Kit and then release the nitrogen. They connect the pump through the Manifold Gauges for Air Conditioning and evacuate both sides at once. The deep vacuum is read on the vacuum sensor of the Digital Manifolds, as the pump gauge shows the pull-down only roughly.
For a standing vacuum test, students close the manifold valves, switch the pump off and watch the reading for a set time. A steady reading means the circuit is tight and dry. A reading that rises and then levels off points to moisture, and one that keeps rising points to a leak. Afterwards they drain the pump and refill it with Replacement Vacuum Pump Oil.
Frequently Asked Questions
What size of job suits a 15 CFM pump?
CFM is the volume of free air the pump moves each minute. At 15 CFM this pump suits larger split, ducted and commercial systems as well as lab trainers. The vacuum a system reaches still depends on leaks, moisture and the hoses used.
Why choose a two-stage pump?
The first stage draws gas from the system and passes it to the second stage, which pushes it out to the air. The first stage never works against full atmospheric pressure, so the pair pulls a deeper vacuum than one stage can.
When should the pump oil be changed?
Change it when it looks cloudy or milky, because moisture in the oil limits how deep the pump can pull. Change it after evacuating a wet system too. Drain it while the pump is warm, then refill with fresh vacuum pump oil.
What does the solenoid or check valve do?
It closes when the pump stops. Oil and air are then not drawn back into the evacuated system if the power fails or the pump is switched off with the manifold still open.
