APC NetworkAIR™ FM-DX 1
Overview
The modular, Floor Mount com-
puter room air-conditioning system
offers efficient, effective and eco-
nomical cooling for a variety of
spaces.
Computer room environmental
requirements now reach far beyond
the confines of the traditional data
center or computer room to encom-
pass a larger suite of applications,
referred to as technology rooms.
Critical environment applications
include:
• Computer rooms
• Telecommunication facilities
• Clean rooms
• Power equipment
• Medical equipment rooms
• Archives
• LAN/WAN environments
A worldwide network of APC rep-
resentatives is fully qualified to
provide engineering, sales, installa-
tion and service for our products.
APC warrants all parts for 12
months from shipment. Extended
warranties are available.
Model
The NetworkAIR FM is available in
two models: FM35 and FM50.
Room Air Distribution
Downflow systems discharge air
into the raised floor plenum. These
systems are suitable for areas with
raised floors greater than 12" (305
mm) high. Return air is drawn in
through the top of the system.
Downflow systems also include a
static regain plenum for each
blower. This evens out velocity pro-
file and increases static
performance while reducing the
noise level. It also allows access to
some components while the system
is operating, without interrupting
airflow.
Upflow systems discharge air into
either a plenum or ductwork. These
systems can be used when a raised
floor does not exist or is not suit-
able for cooling. Air is drawn in
through the front and optionally
from the rear of the system.
The NetworkAIR FM delivers high
volumes of airflow (550 cfm per ton
(160 cfm/kW) to eliminate hot spots
in densely populated environments.
