Profile: International Portland Corp. specializes in downflow containment booths and mobile localized clean air. Our blower motors use ball bearings, and are dynamically balanced to virtually eliminate vibration. Our clean air station models provide the user with a class 100 positive pressure environment wherever localized clean air is required, and their's typical applications are raw material sampling & aseptic connections for bioreactors & fermenters. Our downflow containment booths feature class 100 HEPA filtered air at 90-100 fpm over the entire ceiling, resulting in no updrafts that would contaminate pure raw materials and endanger workers safety.
