Automatic Floor Pressurization System
Overview
The Automatic Floor Pressurization System (AFPS) (ACAC76128) maintains air pressure underneath a raised
floor to a desired setpoint. By modulating fan speed, an AFPS kit for Uniflair Chilled Water (CW) units
compensates for air pressure changes in an active and growing data center.
NOTE: The AFPS is not recommended for Direct Expansion units.
The AFPS kit is supported by the following Uniflair CW models:
