1902

At the turn of the century, stationary air compressors were physically large and heavy requiring bulky-solid foundations. The Rand Drill Company in Painted Post, NY built the first portable in 1902 by mounting a water-cooled stationary compressor on wheels.

1906

The Ingersoll-Sargeant Drill Co. (Easton, PA, Phillipsburg, NJ) merged with the Rand Drill Co. (Painted Post, NY; Sherbrooke, Quebec; Athens, PA; Tarrytown, NY) to form the Ingersoll Rand Co.

1912

Type-12 portables were built; single-staged, water-cooled, driven by steam engines.

1913

A special Tie Tamper compressor was developed for railway service. It consisted of one two-stroke-cycle gasoline engine power cylinder and one Type-12 air cylinder with a common crankshaft.

1917

Type-14 portables were built. This was the first compact portable. A large number were used in World War I.

1921

A more complete line of portables (Type 20) was developed with vertical single-acting duplex water-cooled compressor cylinders direct connected or geared to four cylinder, four-cycle tractor-type gasoline engines. These were very popular through the 20's and several units are still operating today.

1930

Ingersoll Rand introduced the first high pressure portable, the “XL” rated at 330 cfm/300 psig or 270 cfm at 500 psig. Engine was a Waukesha gasoline engine or an IR oil (spark ignited diesel fuel) engine. Compressor was the XOB horizontal, water-cooled, two cylinder, two-stage, double-acting type.

1933

Ingersoll Rand introduced the Type-40 portable, which was the first “V” type air-cooled two-stage portable. At this time, we started rating portables on air delivery rather than on piston displacement. Speed was about 900 rpm.

1938

The “A” line was announced. This was a streamlined, sturdy, compact Type-40 compressor.

1939

Ingersoll Rand introduced the first practical 500 cfm portable with multispeed regulation.
