CHAPTER 2 PREREQUISITES Before you install the filtered enclosure, you need to prepare your site for installation. You must be certain that the area is level and of solid construction. In addition, a dedicated source of electrical power should be located near the installation site to power the filtered enclosure, and other apparatus. Additionally, the enclosure should be strategically placed in the lab to provide efficient workflow.
Chapter 2: Prerequisites Support, Vibration and Movement Requirements At a minimum, the supporting structure usually consists of a base cabinet and chemically-resistant work surface. A stand or mobile bench is not recommended if the enclosure will be used for precise weighing of powders. Location and Air Current Requirements The Purifier Filtered Enclosures have been designed to contain hazards by negating typical cross drafts and turbulence within the opening.

Appropriate Use HEPA filters are high-efficiency particulate air filters having a particulate removable efficiency of 99.99% for particles with a diameter of 0.3 micron.
Chapter 3: Getting Started Set the Face Velocity with the Speed Control Adjustment Adjustment of the speed control gives the correct face velocity and is located behind the front panel. The face velocity should be from 75 to 105 fpm for biohazardous operations. (Consult your Safety Officer for airflow recommendations for your application). Containment is maximized at a setting within this range. Working at the lowest face velocity appropriate for the application will give the quietest operation.
Chapter 3: Getting Started The Purifier Enclosures were also subjected to an industrial hygiene air-monitoring study to confirm the performance of the enclosure for powders. The Purifier Enclosures demonstrated excellent containment when used by an operator using excellent technique and good containment when used by an operator using marginal technique. While no enclosure can compensate for improper technique, these tests confirm the Purifier Enclosures provide a safe working environment.
CHAPTER 4 HIGH PERFORMANCE FEATURES AND SAFETY PRECAUTIONS High Performance Features The patented1 Purifier HEPA Filtered Enclosure and Purifier Class I Enclosure are designed to meet the needs of the laboratory scientist, and provide superior containment while operating at velocities between 75-105 feet per minute. The filtered enclosures have been tested to effectively contain toxic, noxious, and biohazardous materials when properly installed and operated.

Chapter 4: High Performance Features and Safety Precautions 1. Aerodynamic Clean-Sweep™ Air Foil has a unique shape that allows air to sweep the work surface for maximum containment. The Clean-Sweep™ openings create a constant protective barrier from contaminants. Should the operator inadvertently block the airflow entering the air foil, air continues to pass under the air foil and through the Clean-Sweep openings. See Figures 4-1 and 4-3. Figure 4-3 2.
Chapter 4: High Performance Features and Safety Precautions 3. Upper Dilution Air Supply provides bypass air from above the work area. This feature constantly bathes the inside of the sash with clean air and reduces powders, particulate materials and chemical fumes along the sash plane, near the critical breathing zone. Five to seven percent of the required air volume is introduced through the upper dilution air supply.
Chapter 4: High Performance Features and Safety Precautions 14. Space-Saving Design increases effective laboratory workspace, because the impeller and HEPA filter are contained within the enclosure, a separate filtered blower module is not required. See Figure 4-1 15. Fluorescent Lamp is located above the work area, out of contact with contaminated air. A safety glass window beneath the lamp distributes the light evenly across the work surface. See Figure 4-1. 16.
Chapter 4: High Performance Features and Safety Precautions 27. HEPA Filter Access Port to access HEPA filter during filter changing procedures. For harmful powders and particulates, the true bag-in/bag-out procedure is used to properly dispose of the contaminated HEPA filter. See Figure 4-2. 28. Utility Shelves (Not Shown) allows the user to hold items on shelves inside the enclosure. See Chapter 7. 29. UV Closure Panel provides protection when the UV lamp is on.
Chapter 4: High Performance Features and Safety Precautions 12. The sash must remain in the down position while using the enclosure. 13. Proper performance of the enclosure depends largely upon its location and the operator’s work habits. Consult the references in Appendix D. 14. The enclosure should be recertified whenever it is serviced or at least annually thereafter. 15. The HEPA filter provides personnel and environmental protection from particulate matter.
Chapter 4: High Performance Features and Safety Precautions 23. Increase the face velocity by adjusting the speed control of the motorized impeller or change the HEPA filter when the face velocity falls below acceptable limits established by your Safety Officer. 24. Exhaust carbon filters and HEPA filters are disposed as hazardous waste. The user is responsible for recording the chemicals adsorbed or treated by the filters and disposing properly.
CHAPTER 5 APPROPRIATE APPLICATIONS FOR YOUR FILTERED ENCLOSURE Now that the installation of your filtered enclosure is completed, you are ready to use your filtered enclosure. Read this chapter to learn about: 1. Routine Daily Work Procedures. 2. Suitable Applications. 3. Appropriate HEPA Filter Applications, Suitability and Guidelines. 4. Odor Control Carbon Filter Applications. 5. Definition of Terms. 6. Appropriate Chemicals for Odor Control Carbon Filters. 7.
Chapter 5: Appropriate Applications for Your Filtered Enclosure Start-up Turn on exhaust system and accessory light. Turn off the UV light, if equipped. Only raise the sash for loading and cleaning. Check the baffle air slots for obstructions. Allow the enclosure to operate unobstructed for 1 minute. Wear a long sleeved lab coat and rubber gloves. Use protective eyewear. Wear a protective mask if appropriate. Consult your Safety Officer for additional personal protective equipment recommendations.
Chapter 5: Appropriate Applications for Your Filtered Enclosure Suitable Applications NIOSH (National Institute for Occupational Safety and Health, USA) has established guidelines for chemical cartridge and HEPA filtered respirators. Suitable applications for the filtered enclosures are based on these guidelines. As with respirators, chemical contaminants are adsorbed or treated by carbon; particulates, powders and biohazardous materials are filtered by the HEPA filter before air is returned to the room.
Chapter 5: Appropriate Applications for Your Filtered Enclosure Odor Control Carbon Filter Applications (sold as an accessory) Release of low concentrations of vapors effectively adsorbed or treated in carbon based filters. Treatment of low-level carcinogens or suspected carcinogens. (See Chemical Carcinogens in Chapter 5) Procedures that may have traditionally been done on the open bench (low levels only). Odoriferous chemicals that are an unpleasant nuisance.
Chapter 5: Appropriate Applications for Your Filtered Enclosure Saturation Level or Time – There is a limit to the amount of chemical that can be adsorbed by activated carbon, or neutralized by chemically-treated carbon. Once the capacity of the carbon is reached, it is considered to be saturated and will adsorb (or neutralize) no further material; the outlet concentration of the chemical will equal the inlet concentration from that point until the filter is replaced.
Chapter 5: Appropriate Applications for Your Filtered Enclosure Hazardous Misapplications for Odor Control Carbon Filters with Volatile Chemicals There is one scenario where the accessory carbon filter misapplication would be a part of a hazardous condition. If the user continues to operate the enclosure with any of the following conditions present a potentially hazardous condition will exist: 1. The inlet concentration of vapors is greater than the TWA. 2. The carbon filter becomes saturated. 3.
CHAPTER 6 MAINTAINING YOUR FILTERED ENCLOSURE Monitoring airflow and changing the filters is the primary maintenance required. Decontamination may be required and is reviewed in Chapter 6. Certification and recertification is reviewed in Chapter 6. Review this chapter on maintenance for the following: 1. Routine Maintenance. 2. Decontamination. 3. Determination of when to replace the HEPA filters. 4. How to install a new HEPA filter. 5. HEPA filter leak test. 6.
Chapter 6: Maintaining Your Filtered Enclosure Routine Maintenance Schedule Weekly Wipe down the interior surfaces of the enclosure with a disinfectant or cleaner, depending upon the usage of the unit and allow to dry. Using a damp cloth, clean the exterior surfaces of the enclosure, particularly the front and top to remove any accumulated dust. Operate the exhaust system, noting the airflow velocity through the enclosure using a source of visible smoke.
Chapter 6: Maintaining Your Filtered Enclosure Decontamination When used in conjunction with biohazards, the Purifier Class I Enclosure and Purifier HEPA Filtered Enclosure should be decontaminated with formaldehyde gas before: maintenance work in contaminated areas HEPA filter changes moving the cabinet to a new location changing research programs after a gross spill of biohazardous material The procedures for performing a gaseous decontamination are thoroughly outlined in the U.S.
Chapter 6: Maintaining Your Filtered Enclosure 6. Cover the surface of the new HEPA filter gasket with a light coating of silicone grease, if desired. 7. Install the new HEPA filter by pushing it straight into the cabinet, ensuring that it is correctly oriented with the gasket facing up on the exhaust side of the enclosure. The filter gasket is surrounded by a negative pressure plenum and the gasket will not leak. Be sure the filter fits properly. 8.
Chapter 6: Maintaining Your Filtered Enclosure Figure 6-1 HEPA Filter Changing Diagram & Filter Leak Test Diagram Product Service 1-800-522-7658 37
Chapter 6: Maintaining Your Filtered Enclosure HEPA HEPA Filter Leak Test Purpose After installing the new HEPA filter, the HEPA filter should be leak checked. This test is performed to determine the integrity of the HEPA filter, the filter housing, and the filter mounting frames. Leak testing is to be done by a qualified technician with calibrated equipment. Remove the top perforated exhaust cover by using a Phillips screwdriver to unfasten the (2) screws used to secure (2) clips. See Figure 6-1.
Chapter 6: Maintaining Your Filtered Enclosure 6. Set the valve to “DOWNSTREAM.” Place the palm of your hand over the sampling port of the pistol. There should be a strong vacuum at this port. If the vacuum is weak, contact Air Techniques Hamilton Associates. 7. Turn the enclosure on and let it operate for a minimum of 5 minutes. 8. If necessary, adjust the speed control of the enclosure to maintain the following airflows at 90 fpm; 2' (130cfm), 3' (200 cfm, 4' (265 cfm.) 9.
Chapter 6: Maintaining Your Filtered Enclosure Calibrate and Operate the Airflow Monitor Op t ions Guardian Airflow Monitor (LED Monitor) Refer to Figure 6-2 for operation and calibration. Labconco Airflow Monitor / Airflow Switch Operation The Guardian Airflow Monitor (LED) consists of a circuit board and an airflow switch. This switch indicates airflow as safe or low.
Chapter 6: Maintaining Your Filtered Enclosure Calibration 1. Ensure the flow switch and alarm circuit board are installed and operational. 2. Allow the enclosure to operate for at least two minutes. 3. If factory installed, the monitor will alarm at 60±10 fpm with the inflow velocity set at 90±10 fpm. 4. To change the factory setting, set the inflow velocity required by your Safety Officer to the desired alarm condition using the speed control adjustment procedure outlined in Chapter 6.

Chapter 6: Maintaining Your Filtered Enclosure Determination of When to Replace Odor Control Carbon Filters and How to Replace The carbon filters MUST be replaced when any one of the following two conditions are met: 1. The filtered enclosure outlet (exhaust) concentration approaches the inlet concentration, indicating filter saturation. 2. The odor in the work area becomes intolerable or the concentration of the chemical in the work area is greater than the TWA.
Chapter 6: Maintaining Your Filtered Enclosure Time - For applications that have very consistent inlet concentrations and operating time, “Time” can be used to anticipate saturation or TWA levels based on prior experience. However, this does not replace the need for sampling. Consult Labconco technical specialist for an estimate of carbon filter life based on chemical usage. Detector tubes, or analytical instrumentation should always be used to determine concentrations in the carbon filter.
Chapter 6: Maintaining Your Filtered Enclosure Steps for Calculating PPM and Filter Life 1. Determine the amount of the proposed chemical lost to evaporation over a given amount of time. For example, if you use isopropyl alcohol and lose approximately 100 ml per week during 2 hours of use per day. 2. Convert the amount lost into ml/min. For this example: 100 ml X 1 week X week 10 hours use 10 hours = 600 minutes 100 ml lost 600 minutes =.17 ml/min 3.
Chapter 6: Maintaining Your Filtered Enclosure Initial Certification The filtered enclosure has been certified at the factory for an inflow velocity of 90±10 fpm along with the HEPA Filter Leak Test. The filtered enclosure should be certified for the proper inflow velocity. A HEPA filter leak test should be performed once installed to verify there has not been any damage incurred during transportation.
Chapter 6: Maintaining Your Filtered Enclosure Motorized Impeller Replacement The motorized impeller must be replaced as a complete unit. When the motorized impeller is replaced, the capacitor may also be replaced. See Appendix A for Replacement Parts Diagram. See Figure 6-5 for an isometric view of the motorized impeller plenum assembly. The HEPA filter rests on top of the motorized impeller assembly. ! Do NOT contact blower wheel while still in motion.
