Original Instructions CHAPTER 4 THEORY OF OPERATION AND SAFETY PRECAUTIONS All clean benches operate using the following principles: • • Filtration and retention of particulates by High Efficiency Particulate Air (HEPA) filter(s) Laminar airflow The major components in a clean bench are: • • • The HEPA filter The motor/blower to force air through the unit A speed control for the motor HEPA Filters HEPA filters are disposable, dry-type particulate filters.
Chapter 4: Theory of Operation and Safety Precautions Original Instructions HEPA Filters are only effective against particulate material. Gases will pass through the filter. ! Le matériel du filtre HEPA est très fragile. Ne pas toucher ou être en contact avec la surface du matériel. Si vous pensez que la surface d’un filter HEPA est endommagé, NE PAS UTILISER L’HOTTE. Faire tester l’intégrité du filter HEPA par un certificateur qualifié avant d’utiliser l’hotte.
Original Instructions Chapter 4: Theory of Operation and Safety Precautions Laminar Airflow Laminar airflow is defined as the movement of a body of air in a single direction, with a uniform velocity. In practice, the horizontal laminar flow of sterile air in the clean bench flushes out any aerosol generated in the work area of the bench. This sterile airflow maintains the sterility of sterile items inside the clean bench.
Chapter 4: Theory of Operation and Safety Precautions Original Instructions Speed Control ! The speed control should only be adjusted by a qualified certifier. ! Le contrôle de la vitesse doit être réglée uniquement par un certificateur qualifié. The speed control is an electronic circuit that allows the certifier to set the motor speed by adjusting its voltage. ! Never block or obstruct the air intake on the top of the clean bench. ! Ne jamais bloquer l’entrée d’air au dessus de l’hotte.
Original Instructions Chapter 4: Theory of Operation and Safety Precautions unit is connected to electrical service in accordance with local and national electrical codes. Failure to do so may create a fire or electrical hazard. Do not remove or service any electrical components without first disconnecting the clean bench from electrical service. Le Purifier Clean Bench doit être certifié par un technician de certification qualifié avant la première utilization.
Chapter 4: Theory of Operation and Safety Precautions Original Instructions THE HEPA FILTER IN THE PURIFIER CLEAN BENCH WILL GRADUALLY ACCUMULATE AIRBORNE PARTICULATE MATTER FROM THE ROOM. THE RATE OF ACCUMULATION WILL DEPEND UPON THE CLEANLINESS OF THE ROOM AIR, THE AMOUNT OF TIME THE CLEAN BENCH IS OPERATING AND THE NATURE OF WORK BEING DONE IN THE CLEAN BENCH. IN TYPICAL INSTALLATIONS AND USAGE, THE HEPA FILTERS WILL LAST TWO TO FIVE YEARS BEFORE REQUIRING REPLACEMENT.
Original Instructions CHAPTER 5 USING YOUR CLEAN BENCH Starting the Clean Bench To start the Clean Bench, push the blower switch to the “ON” position, as shown in Figure 5-1. Operating the Fluorescent Light To turn on the fluorescent light, push the light switch to the “ON” position, as shown in Figure 5-1.
Chapter 5: Using Your Clean Bench Original Instructions Reading the Pressure Gauge The pressure gauge on the front of the unit displays the total system operating pressure (the negative pressure below the prefilters, plus the positive pressure on the HEPA filter). The pressure gauge reading should be periodically recorded during use. An increase in pressure from the original pressure reading indicates either prefilter or HEPA filter loading.
Original Instructions • • • Chapter 5: Using Your Clean Bench Avoid the use of an open flame. Use proper aseptic technique. – “Sterile Air First” Avoid using techniques or procedures that disrupt the airflow patterns of the clean bench. Final Purging • Upon completion of work, the clean bench should be allowed to operate for 2 to 3 minutes undisturbed, to purge airborne contaminants from the work area.
Original Instructions CHAPTER 6 MAINTAINING YOUR CLEAN BENCH Now that you have an understanding of how to work in the clean bench, we will review the suggested maintenance schedule and the common service operations necessary to maintain your clean bench for peak performance. ! ! 24 Many of the service operations should be performed only by trained and experienced certification technicians.
