Over the years, we have heard many times from users of medical, educational and industrial laboratories that “hoods do not work well” and I have seen many users who have used innovative testing methods to ensure the correct operation of the hood, so that when working with your fume hood. They are protected from damage caused by contact with chemicals. in some cases, tests such as fan noise testing or speed tests with paper only give the user false encouragement, but in practice, chemical vapors leak out of the hood. Be a little more careful about your surroundings! Stainless steel utensils or rusted cabinet handles and hinges, laboratory cabinet keys and locks will change color, and you will see many other signs that indicate air pollution in the workplace. Isn’t it time to think of a way to maintain the safety and health of yourself and your colleagues ?! 

In the 19th century, precise fluid methods were developed to check the performance of hoods. These tests were to test the performance of the hood according to the ASHRAE 110 standard, which ensured the safety of the working environment when using the hood by checking the velocity of the air entering the hood. Over the years, various standards have been developed in industrialized countries in addition to creating safety in the workplace, the issue of environmental protection and reducing energy consumption in the hood to be studied and optimized. Standards such as EN14175, DIN 12924 and ISIRI14037 

Ibad Azma Engineering Company, with its experienced colleagues and mastering the principles of chemical hood operation, is at the service of laboratory experts and scientists to make the laboratory space free of insecurity and pollution for these loved ones. One of the steps in determining the ventilation status of the laboratory is to check the performance of the chemical hood

This is done by a special measuring device to determine the average instantaneous face velocity airflow profile at the fume hood inlet. With the change in the ambient air flow profile, the working conditions of the hood will also change. By examining these changes, the performance of the hood will be determined and it can be said whether the hood creates safety conditions for the laboratory or not.
