A system for compressing and drying a gas generally includes a compressor having multiple stages of compression and a dryer. The compressor includes a first heat exchanger and an after-cooler each of which utilizes a fan. A sensor is provided downstream of the after-cooler. The fan and sensor are in communication with the controller. A final stage compressed gas outlet of the compressor provides hot compressed gas to the regenerative portion of the dryer. Utilization of the final stage compressed gas for regeneration while also utilizing the compressor's after-cooler provides gas which is sufficiently hot to regenerate desiccant in the dryer and allows the communication between the sensor, the controller and compressors to remain intact.
