Porter-Cable branded portable air compressor

This is a portable, oil-free air compressor with a red finish, bearing branding consistent with the Porter-Cable 'Job Boss' line. The unit features a horizontal tank with a large decal stating '150 PSI', '6.0 SCFM @ 90 PSI', and '4.5 GALLON'. The top console includes two universal push-to-connect couplers, a black regulator knob, and an analog pressure gauge marked up to 200 PSI with a 'MAX. 150 PSI' operating note. The frame is constructed of red painted tubular steel with a black foam-grip handle at the base. Visible text includes safety warnings in English, Spanish, and French, along with the instruction 'LOOSEN TO REMOVE CONSOLE FOR REMOTE REGULATION'. Consistent with a used power tool, the exterior shows surface dust, minor scuffs, and debris around the base. The presence of 'Oil-Free' and 'Maintenance Free Pump' text suggests a design intended for light to medium-duty residential or job site use. All branding and technical specifications are as marked on the unit's decals and plates, subject to physical verification of the internal components and motor performance.

Based on the provided image, I am evaluating this portable air compressor bearing branding consistent with the Porter-Cable 'Job Boss' line. From the photo, I can observe a red, 4.5-gallon, 150 PSI horizontal tank unit displaying signs of typical moderate use, including surface dust and minor scuffs. However, I cannot verify the functionality of the motor, the integrity of the oil-free pump, or the accuracy of the pressure gauges from a photograph alone. The estimated value of $75 to $125 relies on the hypothesis that the unit is in safe, full working order and was manufactured by the indicated brand. General secondary market demand for portable, job-site air compressors remains steady, generally driven by DIYers and light contractors seeking utility rather than collectible appeal. Consequently, values are heavily dependent on reliable mechanical performance. To fully test functionality and formally attribute the manufacturer, an in-person physical inspection, diagnostic electrical testing, and a safety review of the pressure valves would be required. While unauthorized reproductions of this specific tier of consumer power tool are relatively unusual, if this unit were found to be a generic copy or unbranded replica, its secondary market value would likely be reduced to the $30 to $50 range, valued strictly for basic parts or raw utility.
