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.
