It is normal for the pump to emit vapor when pumping on a chamber from atmosphere. Since all the air that is removed from the chamber by the pump moves through the oil in the oil reservoir, some of that oil is vaporized when a lot of air is moving through it. When the pressure in the chamber is reduced to a few hundred torr, the oil vapor will be reduced.

We recommend to empty or replace oil at the end of every usage. Don’t leave old oil in the machine. Store the pump and oil in dry clean areas for longest life. The oil can lose its sealing properties if left uncovered. Keep the oil sealed until it’s ready for use.

No, you can use any manufacturer's vacuum pump oil, however fieldpiece oil is optimized for our vacuum pumps and has a specific viscosity for maximum performance.

Excessive moisture is present in the oil indicating that the oil needs to be replaced.

Perform this test to ensure the vacuum pump and your micron gauge are working properly. ...................................................................................................................................................................................................................................................................................................................................................... 1. Connect your vacuum gauge directly to a port on the vacuum pump. ...................................................................................................................................................................................................................................................................................................................................................... 2. Seal the 3 other ports. ...................................................................................................................................................................................................................................................................................................................................................... 3. Ensure the gas ballast is closed. ...................................................................................................................................................................................................................................................................................................................................................... 4. Turn on the vacuum pump to create a vacuum at your gauge. ...................................................................................................................................................................................................................................................................................................................................................... If your gauge measures below 200 microns within 1 minute, you know the vacuum pump and your micron gauge are working correctly. If your gauge does not reach 200 microns, there is a problem with your gauge, the vacuum pump, or both.

The port sizes from left to right are 1/4”, 1/2”, 3/8”, 3/8“.

A gas ballast valve will allow a flow of air into the final part of the compression cycle and allow the vapor to be expelled without condensation or affecting the pump's overall performance. Using the gas ballast valve on the initial pull down helps the pump run smoothly and keeps the oil in good condition.

The vacuum pumps are certified for A2L refrigerant systems. We do not certify the pump against A3 systems, or systems with NH3 - however, as long as the systems are completely void of refrigerant before evacuation, it can be used on those systems.

Yes, The Fieldpiece Vacuum Pumps features a non-mechanical ‘anti-oil suck back’ system which when the machine loses power, will ensure that the oil in the vacuum pump does not migrate into the system or the hose lines. We achieve this by having an ‘open-air’ valve that is sealed when the machine is running, but then slowly opens up to atmospheric pressure when the machine loses power or is switched off. The issue we solve with this feature is the oil-suck back issue which can be very damaging and time consuming to the system should this happen.

Final vacuum is 15 microns

All our vacuum pumps (VP67/VP87/VPX7) have 2 stages.
