The Marvair™ division is one of the world's premiere manufacturers of air conditioners and heat pumps. Our products are designed specifically for the markets we serve - telecommunications, schools, commercial modular buildings and marine.

Our extensive experience and history of continual innovation have made Marvair a world leader. A partial listing of Marvair firsts:


  • First with a wall mount with a factory installed economizer for the telecommunications market, the ComPac® II
  • First with an interior vertical heat pump, the Scholar, designed specifically for the classroom.
  • First with a one ton wall mount

The ComPac® I and ComPac® II air conditioners are used more than any other air conditioners to cool electronic and telecommunication equipment shelters throughout the world. Both units have the necessary controls and safeties for operation in cool or cold weather. The primary difference in the two units is that the ComPac® II has a factory installed economizer. The economizer cycle uses outside air, when cool and dry, to cool the telecommunications equipment. The economizer cycle can reduce run time on the compressor by up to 75% thereby extending compressor life, reducing downtime, and energy costs.

The ComPac® I and ComPac® II are built in cooling capacities of 1, 1-1/2, 2, 2-1/2, 3, 3-1/2, 4 and 5 tons. Units are built for operation on a variety of electrical supplies - 208/230v, 380v, and 460v and for either 50Hz or 60Hz. Units are listed by Underwriters Laboratories (U.L.) and rated according to the Air Conditioning and Refrigeration Institute Efficiency Standard 210.
