Weighing in at only 163lbs (dry), and with one of the smallest footprints in the market, the new BOSS BA440 (p/n 20013-006) packs a punch producing up to 40cfm @ 150psi!

The new BOSS BA440 is now even lighter smaller and more efficient! By eliminating the coupler, we have reduced the weight by 20 lbs, shortened length plus made the routine maintenance even easier. Plus we added an hour meter! At the heart of the system is an aluminum, single stage, V4, pressure and splash lubricated reciprocating air compressor. Fully assembled in the U.S., the aluminum compressor assembly offers lighter weight and higher thermal efficiency than cast iron compressor assemblies. The BA440 includes an internal oil pump for increased lubrication over that of splash lubrication only compressors.

And here is what's exciting about the BA 440!

Now, with our new design, we are as flexible as your hydraulic requirements. From 8 GPM to 12 GPM, we can offer you a variety of outputs to fit your demands!

See the chart below for all the hydraulic pressure and flow requirements.

30/100 (150 max) 1,150 8 1,850 (2,100 max)
35/100 (150 max) 1,400 10 1,850 (2,100 max)
40/100 (150 max) 1,650 12 1,850 (2,100 max)

The compressor is direct coupled to a gear-type hydraulic driven motor, no need to replace and tension belts when time is of the essence!

Routine maintenance items are accessible without the removal of the canopy.

The 160lbs dry weight of the BA440 is half that of competitive brands due to the aluminum compressor, enclosure and small footprint. The aluminum enclosure not only reduces weight, but also is rust resistant.

Also, included standard with the Boss BA440 are an integrated hydraulic system cooler, integrated solenoid and relief valve, 12 VDC fan assembly (24VDC optional), heavy-duty filtration and 18-month warranty.
