AIR RESERVE

BUILD AROUND YOUR SPACE.

Tank capacity changes how much air the system has in reserve. Choose the size around available space, compressor setup and the way you plan to use the system.

WHAT MATTERS
01

CAPACITY

More tank volume gives the system more reserve air. Smaller tanks trade capacity for a more compact install.

02

PORT LAYOUT

Port count and placement affect how cleanly you can route management, compressors, drains and accessories.

03

200 PSI RATING

This tank is listed with a 200 PSI working pressure rating. Keep every component in the system pressure-compatible.
