About HallowEll.com
Hallowell EMC was incorporated in 1988 after the dissolution of Rusz Instruments following the transfer of technology involving the AV500 ventilator to Bear Medical of Riverside California. A simplified version of the AV500 with an extended operating range for veterinary use was partially complete at the time. At Hallowell EMC this project was finished and marketing began with the Model 200 Veterinary Anesthesia Ventilator.
