Fume Hood Exhaust Systems are an important component of the building HVAC system and the safety components of a laboratory. There are many standards that these systems can be adapted to, as there are many manufacturers with numerous designs. CON-TEST can conduct tests from the basics to face velocity; air induction, air intrusion and smoke capture to containment test as defined in the CSA standard for fume hood testing. General maintenance of the sash and pulley systems keeps the protective screen in place. Calibration of the alarm to monitor the airflow requirements is essential. CON-TEST personnel will review appropriate use methodology with the users as need requires.
