Is there a Sherpa OPS compressor?
Not in the Sherpa 4×4 product listings and data-sheet index reviewed for this article. The official pages cover the BOX AIR and BIG V4 compressors, but do not confirm an OPS model. “OPS” may be a mistaken name or refer to something not identified in those materials; without confirmation, its specifications, accessories, and vehicle connections remain unknown.
Sherpa’s 4WD compressors collection and data sheets and manuals are useful starting points for checking model names. The data-sheet index links manuals for BOX AIR and BIG V4, not an OPS manual.
What the documented Sherpa compressors offer
The BOX AIR and BIG V4 are documented alternatives, not verified versions of an OPS. Their listed figures come from Sherpa’s undated U.S. product pages reviewed in 2026; they are manufacturer specifications, not independent test results.

How to read BOX AIR’s pressure ratings
Sherpa lists several distinct pressure figures for BOX AIR. Its tank pressure switch cycles on at 120 PSI and off at 150 PSI; the relief valve is set to 180 PSI; and the technical table gives a maximum operating pressure of 200 PSI. These figures describe different ratings and functions, so they should not be treated as interchangeable or as a single recommended tire-inflation pressure.

What Sherpa claims about BIG V4 inflation speed
Sherpa says BIG V4 can inflate a 37-inch tire from 9 to 38 PSI in “just over 2 minutes 30 seconds,” or inflate two 37-inch tires simultaneously in under four minutes. It also states that a 215/60R16 tire can go from 0 to 35 PSI in under 50 seconds. These are manufacturer claims; they were not independently tested in the sources reviewed. Actual results can depend on conditions and setup, so treat the figures as Sherpa’s stated examples rather than a guaranteed outcome for every vehicle.

What to confirm before buying or installing
- Exact model: Check the product label, invoice, or seller listing. Do not assume “OPS” means BOX AIR or BIG V4.
- Electrical requirements: Match the compressor’s stated current draw, fuse, and cable requirements to the exact model. The available data do not establish OPS cable requirements.
- Connections and accessories: Verify hose length, fittings, and adapters against the compressor itself. Sherpa’s air-accessory collection identifies a replacement hose and hose adapter for BIG V4; their compatibility with an OPS unit is not established.
- Manual and operating limits: Use the manual for the confirmed model for installation, electrical connections, operating limits, and maintenance. The data-sheet index currently links BIG V4 and BOX AIR manuals.
