Before you pick a vacuum source
SYS-GRP workholding is designed to work with a wide range of vacuum sources. You do not need a single "approved" pump. What matters is consistent airflow and a usable vacuum level for your workflow.
Rule of thumb
- Nearly any vacuum source capable of about 0.7 to 1.0 CFM (about 20 to 28 L/min) can drive SYS-GRP for single pod and small setups.
- More airflow and continuous duty capability improves consistency for multi pod arrays, porous materials, and longer sessions.
Practical airflow examples (CFM)
Workflow / scenario | Practical airflow range | What to expect |
Single pod, non porous material | 0.7 to 1.5 CFM (20 to 40 L/min) | Strong hold with simple plumbing |
2 to 4 pods, general bench work | 2 to 4 CFM (60 to 115 L/min) | More stable hold, faster recovery after small leaks |
Multi pod arrays, porous material, or production duty | 5+ CFM (140+ L/min) | Best consistency, especially with valves and zoning |
Vacuum source options by category
Below are several vacuum sources we have tested internally, or have been validated through trusted users during SYS-GRP development. This list is not exhaustive.
1) Bench friendly continuous duty sources
- Vacupress Compact 150 - Designed for the home workshop. A solid starting point for a single pod or small arrays.
- Vacupress Compact 300 - More headroom for multi pod setups.
2) Portable / jobsite sources
- Grabo Pro-Lifter 20 - Portable vacuum source when you need to take SYS-GRP workholding mobile.
- Dewalt Grabo - Portable option on the Dewalt battery platform.
3) Budget pump options (with caveats)
- VIVOHOME Rotary Vane Air Vacuum Pump - Budget oil cooled pump. Requires ongoing oil maintenance and adapter fittings.
- Win Outdoor 2- Stage 50L/m Oil Free Lab Vacuum Pump - Budget oil less option. Includes basic push to connect fittings and an air filter to help protect the pump from debris.
We will continue to add options here as more testing and feedback comes in.
