Ingersoll P1.5IU-A9 vs Ingersoll-Rand SS3L3
Both the Ingersoll P1.5IU-A9 and the Ingersoll-Rand SS3L3 are stationary air compressors in the same price bracket, listed at $1,406.24 and $1,353.99 respectively, yet they target very different shop requirements. The P1.5IU-A9 is a corded electric 115-Volt AC unit with a 20-gallon tank suited to lighter-duty stationary use, while the SS3L3 is a 3-horsepower single-stage compressor with a 60-gallon tank running on 230-Volt single-phase power and built for sustained high-demand applications. Based on specs and verified owner reviews, the right choice comes down to tank capacity and the power supply available in your space.
Quick winner
The Ingersoll-Rand SS3L3 wins on tank size (60 gal vs. 20 gal) and is built for heavy shop use; the Ingersoll P1.5IU-A9 suits buyers who need a compact 115-Volt unit with a smaller footprint.
