Rubber isolators reduce the transmission of vibration and noise while vertical discharge fans direct sound away from surrounding structures.

Durable Performance

Solid construction with microchannel aluminum, vinyl-coated fan guards and scroll compressors ensure long-lasting, efficient performance.
