About Cobeal

Bo Erik Ingemar Hollsten, a Swedish mechanical engineer with a history in HVAC marine engineering and critical environments opened VISA® in 1963.

The company's first product line was industrial HVAC and filtration equipment for "Telefonos Ericsson" (which later became Telmex) in Mexico.

Under Climatron, the company was an official Licensee of Cambridge Corporation, with filters originally derived from the technology used during WWII to remove radioactive particles from the exhaust air of the sites of the Atomic Energy Commission. 

Cambridge Corporation was a consequence of the original Manhattan project located in Syracuse, New York. 

Our company was formed to manufacture and sell the then declassified biological and radiological filters to be used in the disposal of radioactive waste. This filter was known as the "Absolute Filter". The Cambridge Corporation filters soon became the industry standard. 

VISA® and COBEAL's filtration designs are derived directly from this technology.
