What the 350C mounts to and what its 12V rating means
This unit is made to live on a vehicle, not ride in a toolbox. VIAIR supplies four mounting points, vibration isolators and hardware, so you can secure it in a vehicle, trailer, workshop or custom pneumatic setup.
It draws from a 12V source. We recommend confirming your vehicle, trailer or bench supply delivers 12V and that you have a solid spot to bolt the body down before you buy.
Check the air system itself next. Onboard air, air bags, air horns and load-leveling gear each carry their own pressure and flow requirements, so match those against this compressor before price enters the picture.

Where its duty rating stops
The 100 percent duty cycle applies at 100 PSI. Read it as a continuous-run rating at a stated pressure, not a blanket promise across every pressure the pump can reach.
The unit is rated to 150 PSI and moves 1.17 CFM free-flow. Treat those as output specs rather than proof your bags, horns or tires will fill as quickly as you hope, since the rest of the system adds its own restrictions.
We'd skip it if you want one compressor to move between cars. This one is built to stay mounted.
Continuous-duty rating applies at 100 PSI, not at every pressure.

Reviews give you a sense of how other buyers have fared with this compressor over time. That context matters when you are weighing a permanent install against a cheaper unit you might replace sooner.
Power, wiring and mounting checks before you install
The 350C needs a 12V feed. Confirm whether your intended circuit can carry the compressor's draw and whether a relay or dedicated wiring is needed for your build.
Plan the mounting surface as well. The four points and vibration isolators help, but they still need something solid enough to handle running vibration.
If your system uses a tank, pressure switch or a specific port size, verify those connections before you commit to the layout.
Who should buy the VIAIR 350C
Buy it if you want a permanent onboard air source for air bags, load-leveling, air horns or a workshop build, and you are ready to handle 12V wiring and a hard mount.
Skip it if you need a portable inflator, or if your system's pressure and flow needs have not been checked against the 100 PSI continuous rating.
Before ordering, confirm your 12V supply and mounting location, then buy.
