Description
The RovAir is Air Venturi’s mid-size portable compressor: oil-free, dual-fan cooled and up to 25% faster than the Nomad Nano. It runs on wall power or a 12V car battery, so it works at home and in the field.

Home and field fills for one or two rifles, including your rifle’s own air bottle. More capacity than the Nano for regular shooting. It fills rifles directly; to keep large storage tanks full, choose the Krypton.

How to fill your rifle
- Set your target pressure on the gauge (adjustable auto shut-off, up to 4500 psi). Use your rifle’s fill pressure, never more than the rifle is rated for.
- Close the bleed / pressure-release valve (clockwise until snug).
- Connect the hose to your rifle or its bottle and check that the quick-disconnect collar is fully forward and locked: give it a tug.
- Turn the power on so the fans run, then start the compressor.
- If the compressor stops by itself within a few seconds of starting, start the fill with the bleed valve open and close it after a few seconds of running.
- Stay with the compressor and the rifle for the whole fill.
- When it reaches your set pressure the compressor stops. Open the bleed valve to release the pressure in the line.
- When the compressor gauge reads 0, disconnect the hose.
Care and safety
- Bleed the line every time: at the end of each fill, and before restarting if you stop part-way. If the line still holds pressure, the compressor will shut itself off a few seconds after you restart it.
- Filter: Air Venturi recommends replacing the output air filter every 2–3 hours of use.
- Direct fills only: made to fill PCP rifles and pistols directly. Air Venturi says not to use it on stand-alone SCUBA or SCBA tanks; doing so can damage the compressor and voids the warranty. For storage tanks, see the Krypton.
