Energy-efficient Green Drive Technology saves on electricity. Use them for jobs that need a little air or ones that need it all the time.

Manufacturer recommends replacing diaphragms ever 18 months for optimal performance, which Blue Diamond provides one new set of replacement diaphragms in each new unit.
Connections: The air outlet features internal threading for use with the provided barb adapter, but for 3/8" tubing, we advise using the supplied rubber elbow instead. If you're using larger tubing, you can connect it directly to the smooth outer surface of the air outlet. The 14mm outlet can support 1/2" tubing, while the 18mm outlet can handle 5/8" or 3/4" tubing. If you intend to use 1/2" tubing with the 18mm outlet, you will require additional adapters.
