IMPROVED PERFORMANCE and

REDUCED MAINTENANCE

Backward curved fans discharge air radially

allowing for uniform static pressure across

the raised ﬂ oor. Traditional forward curved

fans blow air in a high velocity stream with

high velocity pressure and minimal initial

static pressure, prohibiting optimal airﬂ ow

through the raised ﬂ oor close to the CRAC.

One of the key features of backward curved

fans, commonly referred to as plug fans, is

that the motor and fan are integrated into

a single unit. Unlike forward curved fans

that have a separate motor, pulley, belt and

in some cases a shaft, plug fan blades are

directly connected to the motor. This elimi-

nates the need for monthly maintenance,

belt replacement and all belt dust.

In the unlikely event of a fan failure,

the entire fan unit is removed. Removal is

easy with the unfastening the screws and

disconnection of the electrical service.

The replacement fan is set in place, electri-

cal connections are made and then the fan is

bolted in place.

MISSION CRITICAL COOLING

gForce by Data Aire provides the most advanced

features in mission critical cooling equipment

available on the market today. These units are

the most efﬁ cient and economical while comply-

ing with strict environmental requirements.

Incorporating backward curved plenum fans

with electronically commutated (EC) motors

these units supply radially dispersed cooling

air at lower speeds allowing for more uniform

static pressure across the room. These fans, with

integral DC motors, run at lower temperatures

providing more net cooling from the computer

room air conditioning (CRAC) unit. DC motors

are more energy efﬁ cient, providing an on-go-

ing savings year after year. gForce efﬁ ciency is

also increased by the use of riﬂ ed tubing in the

cooling coils to promote the greatest amount of

heat transfer. gForce single circuit DX units are

available in 7 through 46 kW with either upﬂ ow

or downﬂ ow air distribution in air cooled or wa-

ter/glycol cooled models. Each unit is factory

run tested and put through a vigorous quality

control procedure
