Overview
The Ingersoll P1.5IU-A9 is a corded electric air compressor with a 20 gallon tank, running on standard 115 volt power. At roughly 200 pounds and over 3.5 feet long, it is built as a stationary shop unit rather than something you carry to a job site.
A 20 gallon tank puts this in range to run finish nailers, impact tools or spray equipment for stretches without the motor cycling every few seconds. The corded 115 volt motor plugs into a standard household circuit rather than needing shop wiring, though its size and weight point to a fixed spot in a garage or workshop. No CFM or horsepower rating is given, so pair it against tools by tank size and voltage rather than output claims.
- 20 gallon air tank
- 115 volt corded electric motor
- 45 x 24 x 20 inch footprint
- 90.7 kilogram (about 200 lb) unit weight
Who it's for
Fits someone setting up a home garage or small shop who needs a dedicated air supply for nail guns, impact wrenches or paint sprayers. Not a fit for anyone wanting a compressor they can move between job sites in a truck bed.
Strengths and trade-offs
Drawn from this product's published specifications.
- 20 gallon tank for extended air tool use
- Runs on standard 115 volt outlet
- Corded electric, no fuel or battery to manage
- About 200 pounds, not easily moved
- No CFM or horsepower spec listed
Performance notes
With a 20 gallon tank, the compressor stores enough air to run intermittent tools like nailers or impact drivers without the motor kicking on constantly. Running on 115 volt AC power keeps it compatible with a standard outlet, avoiding the need for a 220 volt line. At 90.7 kilograms it is not something one person relocates casually, so plan for a permanent placement before installing it.
