SYS-GRP FAQs: Common Setup and Compatibility Questions

Question	Short answer
What vacuum source can I use?	Most vacuum sources used in a shop will work. For small setups, ~0.7 to 1.0 CFM is a good rule of thumb.
What tubing size fits SYS-GRP pods?	1/4 in tubing with 1/4 in push-to-connect fittings on #10-32 heat-set inserts.
BenchGrip Minimus variants: what is different?	Single vs dual port (chaining), and center vs offset mounting (fit/clearance).
What are the small black washers?	Sealing washers used when a fastener passes through the vacuum zone.
How do I use AnchorDogs?	Use AnchorDogs to fasten from the top of a Doghole surface. See the step-by-step guide below.
Can I use elbows or other fittings?	Yes. Swap the straight fitting for an elbow. Snug only. Optional sealant.

Vacuum sources (pumps, portable options, and minimum airflow)

SYS-GRP is designed to work with a wide range of vacuum sources. What matters is consistent airflow and a usable vacuum level.

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 and porous materials.

SYS-GRP pods ship with a 1/4 in push-to-connect fitting threaded into a #10-32 heat-set insert.

Recommended tubing: We recommend PU tubing to minimize kinks and maximize flexibility. Example link: PU tubing

Holding force is the same across Minimus variants. The differences are configuration and fit.

Single port: You will typically need a splitter or manifold to run more than one pod from one vacuum source.
