CHAPTER 4 THEORY OF OPERATION AND SAFETY PRECAUTIONS The Bedding Disposal Station operates using the following principles: • • Filtration and retention of particulates by High Efficiency Particulate Air (HEPA) filter Directional airflow The major components in the Bedding Disposal Station are: • • • • • • The prefilter The HEPA filter The activated carbon/alumina postfilter The impellers to force air through the unit A speed control for the motor Station air intakes (baffles) and ductwork Product Servic
Chapter 4: Theory Of Operation And Safety Precautions Prefilter The prefilter is located just below the HEPA filter. Its purpose is to lengthen the operating life of the HEPA filter by removing large particles before they can block it. ) REGULARLY SCHEDULED INSPECTION AND REPLACEMENT OF THE PREFILTER IS KEY TO MAINTAINING PROPER OPERATION OF THE ENCLOSURE. HEPA Filter HEPA filters are disposable, dry-type particulate filters.
Chapter 4: Theory Of Operation And Safety Precautions Figure 4-1 The Activated Carbon/Alumina Postfilter The postfilter in your Bedding Disposal Station is unique. Inside of its polyester media are granular activated carbon for the adsorption of odors, plus activated alumina impregnated with potassium permanganate, for additional removal of odors and light gases.
Chapter 4: Theory Of Operation And Safety Precautions Directional Airflow Directional airflow also plays a key role in the Bedding Disposal Station’s performance. Air is drawn into the front of the station and odors. This “curtain” of air makes it difficult for aerosols and odors to escape out of the work area and into the outside environment. This airflow is often calculated and referred to as the Average Inflow Velocity. This is shown graphically in Figure 4-2.
Chapter 4: Theory Of Operation And Safety Precautions Impellers The impellers pull air into the front of the station, through the pre- and HEPA filters, and then discharge it through the postfilter. Speed Control ! The speed control should only be adjusted by a qualified certifier. The speed control is an electronic circuit that allows the certifier to set the impellers’ speed by adjusting its voltage.
Chapter 4: Theory Of Operation And Safety Precautions Safety Precautions The PuriCare Bedding Disposal Station is NOT a biosafety cabinet. Do not use this device for the containment of biohazardous, toxic, flammable, or explosive materials. If you have questions regarding the operation of this device, contact Labconco at 800-821-5525 or www.labconco.com. The PuriCare Bedding Disposal Station should be certified by a qualified certification technician before its initial use.
Chapter 4: Theory Of Operation And Safety Precautions without first disconnecting the PuriCare from electrical service. Avoid the use of flammable gases or solvents in the PuriCare. Care must be taken to ensure against the concentration of flammable or explosive gases or vapors. An open flame should NOT be used in the PuriCare. Open flames may disrupt the airflow patterns in the station or damage the filters’ adhesive.
Chapter 4: Theory Of Operation And Safety Precautions ! ) Proper operation of the station depends largely upon its location and the operator’s work habits.
