Who It’s For
- Residential techs: Reliable day-in, day-out pulls on splits, cassettes, and heat pumps.
- Commercial contractors: Higher CFM options to accelerate evacuations on larger plant.
- Service managers: Lower downtime and simple maintenance = better utilisation across the team.
Quick Care Tips (Maximise Pump Life)
- Warm the pump for a few minutes, then open the gas ballast early in the pull to help drive off moisture.
- Use clean vacuum-rated oil; change when it darkens/clouds or after wet systems.
- Keep hose runs short with minimal fittings; use core-removal tools to speed evacuation.
- Store the pump upright and capped to keep dust and moisture out between jobs.
Why Yellow Jacket Pays Off

FAQs
What CFM do I need?
For single and multi-split systems, 3–5 CFM suits most jobs. Step up to 7–11 CFM for larger charge volumes or commercial plant to reduce evacuation time.
How often should I change the oil?
Check after every wet system. As a rule, change when oil looks cloudy or discoloured, or per manufacturer guidance during heavy use.
Do these pumps include gas ballast?
Current models feature gas ballast to help reduce moisture contamination during evacuation.
Can I run the pump in high ambient temps?
Yes—thermal protection helps, but ensure good airflow around the pump and follow duty recommendations.
