4.3.3.2 Blower Packs
Condair blower packs create an air stream to allow absorption of the atmospheric steam in the condi-
tioned environment. Once the steam is absorbed, the humidity will disperse evenly throughout most
conditioned environments without the need of further mechanical assistance (except when mechanical
obstructions, localized variances in temperature, infiltrating air, or materials that have equalizing moisture
effects on the surrounding atmosphere are present). Refer to
"Space Distribution Control Design" on page 45
The Nortec RS Space humidifier comes fully factory-assembled with its own built-on blower pack (with
internal power supply, steam and condensate connections). The remote-mounted blower pack is capable
of dispersing 5-100 lb/h (2-45 kg/h) of steam, and requires an external 120 VAC, 15 A power supply, as
well as atmospheric steam line and condensate connections. Refer to
.
The blower pack has two speed settings – High speed setting which provides shorter absorption dis-
tances, and the Low speed setting which offers quieter operation but requires longer absorption distance.
For more information refer to the Blower Pack Installation Operation and Maintenance Manual (Condair
document 2582277, available from
).

The following is a list of requirements for installing remote-mounted blower packs:
The atmospheric steam line must rise straight up 12 in (300 mm) from the Nortec RS humidifier
before continuing on to the blower pack. Other steam line installation requirements are described
"Atmospheric Steam and Condensate Lines" on page 34
The condensate line from the blower pack can be routed to either an external drain or the humidifier
fill cup. It must have a constant minimum downslope of 1.2°, with no restrictions. The condensate
trap should have a diameter of 6 in (150 mm) and must be located minimum 12 in (300 mm) below
the blower pack condensate port.
