Specifications
Data center air filtration as defined by ISO Class 8 per ISO 14644-1
with a 95% upper confidence limit.
NOTE:
This condition applies only to data center
environments. Air filtration requirements do not apply to IT
equipment designed to be used outside a data center, in
environments such as an office or factory floor.
NOTE:
Air entering the data center must have MERV11 or
MERV13 filtration.
Air must be free of conductive dust, zinc whiskers, or other
conductive particles.
NOTE:
This condition applies to data center and non-data
center environments.
•
Air must be free of corrosive dust.
•
Residual dust present in the air must have a deliquescent point
less than 60% relative humidity.
NOTE:
This condition applies to data center and non-data
center environments.
Specifications
<300 Å/month per Class G1 as defined by ANSI/ISA71.04-1985.
<200 Å/month as defined by AHSRAE TC9.9.
Specifications
5°C to 40°C at 5% to 85% RH with 29°C dew point.
NOTE:
Outside the standard operating temperature (10°C
to 35°C), the appliance can operate continuously in
temperatures as low as 5°C and as high as 40°C.
