Typically 60-80% of the LCC of a filter is the energy consumption.

What if we gave you free filters in exchange for 50% of your Energy savings?

LCC & TCO Support Tools

Clean air solutions

LCC = Investment + PCenergy + PCmaint. + PCcleaning + PCdisposal

• Investment – capital cost of filters, frames, installation

• PCenergy – present total cost of power

• PCmaintenance – present total cost of maintenance including filter replacement, etc.

• PCcleaning – present cost of duct cleaning

• PCdisposal – present total cost for removal and disposal of the used filters

components of Life-Cycle Cost

Clean air solutions

• PCEnergy – the current cost of energy Energy (E) = [(Q * ΔP * T)/(ŋ * Co)] * Pc

Q – Air flow, m3/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

energy equation for life-cycle cost

Camfil Design vs. “Copy me” Design

Chandler or ‘V” type pleat will blind causing rapid increase in pressure drop.

Uniform radial style pleat loads evenly resulting, in lower

average pressure drop and long loading curve.

Background to cleanroom ventilation

Particles displaced

Particles diluted

Clean air solutions

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)

Clean air solutions

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

2. aerosol concentration – different generation techniques – generator input conditions – volume flow rate through filter

3. filtering velocity – system conditions

Why is Room-Side Certification Important?

or engineer select & why?

Updated Cleanroom Standards:

• 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
