Clean Room Ventilation Requirements

A volume of air equivalent to the room volume that enters and exits a room.

Clean room ventilation requirements.

The hvac system for cleanrooms is a specialized field requiring thorough understanding of cleanliness guidelines airflow streams room pressurization temperature humidity and. Most clean rooms fall into the class 6 7 or 8 categories. Ventilation and air conditioning for clean rooms clean rooms place the highest demands on ventilation and air conditioning. Clean room classifications requirements for a broad range of industries proper cleanroom requirements and standards are maintained throughout all industries that require the use of a cleanroom.

At cfw we understand that cleanrooms must fulfil exacting standards. 60 air changes an hour means that a volume of air equivalent to the room passes through the room each minute. Increasing ventilation can also reduce risks from particles resuspended during cleaning including those potentially carrying sars cov 2 or other contaminants. Some of the industries that benefit the most from clean room classifications and iso class.

The number of air changes required to meet specification is. As an established leader in air technologies we offer air handling solutions customised for use in clean rooms. Sensitive individuals may include pregnant women and people with asthma. These requirements are defined in federal industry standard 209 and iso 14644 1.

Design of the ventilation system shall provide air movement which is generally from clean to less clean areas. A clean room gmp cleanroom in my mind are a combination of engineering design fabrication finish and operational controls control strategy that are required to convert a normal room to a clean room. We provide blowers designed to overcome customer specified static pressure and provide the required airflow as well as filter fan units. If any form of variable air volume or load shedding system is used for energy conservation it must not compromise the corridor to room pressure balancing relationships or the minimum air changes required by the table.

It takes an incredible amount of technology to achieve and maintain these objectives. Fda guidelines only specify a minimum of 20 air changes per hour. Sensitive individuals should avoid cleaning if possible and consider leaving the room during cleaning.
