About us

Quad-State Air Compressor Sales & Service covers Western Maryland, Southern Pennsylvania, the Eastern Panhandle of WV, and the Northern Shenandoah Valley* of Virginia.

Since starting in 1994, Quad-State Air Compressor Sales & Service (formerly R.L. Bentley, Inc.) has expanded into the four-state region servicing local businesses' compressed air needs.

In 2002, Quad-State Air became an authorized distributor for Kaeser rotary screw compressors, as well as Saylor Beall & Curtis piston compressors.

Quad-State Air expanded our product line to include other compressor lines such as Champion, Emglo/Jenny, Rol-Air, and Puma in 2004.

Through continual training such as the compressed air challenge and Kaeser Kfact programs, Quad-State Air will always offer the best in compressor service and system design.

We have found your technicians to be extremely knowledgeable and capable, and your responsiveness at all hours is unparalleled in the construction and service industry."
