components of Life-Cycle Cost LCC = Investment + PC energy + PC maint. + PC cleaning + PC disposal Investment capital cost of filters, frames, installation PC energy present total cost of power PC maintenance present total cost of maintenance including filter replacement, etc. PC cleaning present cost of duct cleaning PC disposal present total cost for removal and disposal of the used filters
energy equation for life-cycle cost PC Energy the current cost of energy Energy (E) = [(Q * ΔP * T)/(ŋ * Co)] * Pc Q Air flow, m 3 /s (cfm) ΔP Average filter pressure loss, Pa (inwg) T Operation time, hr ŋ Fan efficiency, % Co Constant, 1000 in SI units, 8515 in IP units Pc Cost of Power, $/kwh
Camfil Design vs. Copy me Design Uniform radial style pleat loads evenly resulting, in lower average pressure drop and long loading curve. Chandler or V type pleat will blind causing rapid increase in pressure drop.

Background to cleanroom ventilation Particles displaced Particles diluted Class 100 / ISO5 Class 10,000 / ISO7 & 100,000 / ISO8
Turbulent cleanroom ventilation a component of contamination control Clean air supply should dilute any residual particles shed from people and other emission sources and then be removed by the extract system Ventilation effectiveness defines how good the system is at diluting contamination and hence how much air is needed (ac/hr)
Ventilation Effectiveness key to successful contamination dilution Typical USA Air can also bounce off the floor and entrain contaminants
Ventilation Effectiveness key to successful contamination dilution Typical EU/Asia Cleaning could also be a concern
Pharmaseal G Standard for Life Science applications. Typical Model - 80% of Install Base
Fully Equipped for GMP In situ Controls Integrated Aerosol Dispersion Ring PAO Test Pressure Drop Airflow Velocity Hinged Grille Quick closing with ¼ Turn Fasteners Immediate access from room-side 100% Sampling Port Aerosol Injection Port
Pharmaseal: Long Term Security No Risks for Leaks During Life Cycle Airtight by Design Fully continuous welded. Airtight continuity with clean room ceiling with permanent trim standard design. Universal Knife Edge Housing Silicon gel (recommended). Immediate seal without mechanical strength. Gel belongs to filter. Expanded PU Gasket possible. Cleanroom False Ceiling Expanded PU Gel
factors influencing filter penetration 1. aerosol particle size different aerosols different generation techniques 2. aerosol concentration different generation techniques generator input conditions volume flow rate through filter 3. filtering velocity system conditions LEAKS
HEPA filters should be tested at the Most Penetrating Particle Size (MPPS) Example performance of a HEPA Filter 100.000 Viruses Droplet Nuclei Bacteria 99.998 0.12 micron Efficiency % 99.996 99.994 99.992 0.3 micron 99.990 99.988 0.01 0.1 1 Particle Size (µm) MPPS (0.16-0.2 micron) 31 CAMFIL FARR 2013-05-04
Room-Side Certification Control Panel - Centralized & Ergonomic: Injection + control from room-side requiring only 1 person to test filter. Quick plus airtight connection using the quick disconnect ports. Aerosol Dispersion Ring: PAO test performed in compliance with ISO-IEST standards. NO PAO IN HVAC DUCTING for fire safety & increased filter life.
Why is Room-Side Certification Important? How & where to use aerosol injection is often overlooked during the design process What location should aerosol be introduced? What type of terminal housing should an owner or engineer select & why? 1 2 1 2 3 AHU Injection? Ductwork Injection? Hood Injection? 3 4 RA Injection? 4

Updated Cleanroom Standards: CAMFIL FARR 2013-05-04 41 Simplify the classification process and if possible remove the need to evaluate the 95% UCL for 2-9 sample locations Review the classification procedure and make it more applicable to rooms in operation. The contamination isn t expected to be evenly distributed an assumption the current statistical approach makes. Avoid any radical changes to the principals of the current ISO cleanliness classes 1-9
