About this product
This Speedaire 40Jj58 is a stationary, 2-stage diesel-powered air compressor, engineered for heavy-duty applications. It features a powerful 9.1 hp Kohler engine, delivering an impressive 18.3 cfm free air flow rate at 175 psi maximum operating pressure. The unit incorporates a 30-gallon horizontal air tank and offers both electric and recoil starting for convenience. With a substantial weight of 522 lbs, it is clearly intended for fixed installation.
Our take
For serious workshops or industrial environments, the Speedaire 40Jj58 is a beast. The 9.1 hp Kohler diesel engine provides ample power, translating to a robust 18.3 cfm at 175 psi, which is excellent for demanding pneumatic tools. The 30-gallon tank is a good size for maintaining steady pressure during use. Given its 522 lb weight and stationary design, this isn't something you'll be moving around often, which makes sense for its power output. The dual electric and recoil start options are a nice touch for reliability, ensuring you can get it running even if one system fails. It's an investment, but it’s built for heavy, continuous work.
