VAPORMIST
®
DISPERSION
The SDU can be mounted directly
above the VAPORMIST.
SDU-I:
Provides instant, internal absorption
The Space Distribution Unit Internal Absorption
(SDU-I) disperses humidity with no visible vapor trail
or wetness, making the VAPORMIST
®
with an SDU-I
ideal for use in finished spaces. When room RH is 45%
or less, the SDU-I fan mixes room air and steam to
ensure complete absorption before discharge as
humidified air. The SDU-I is available for models VM-2
through VM-8, and all VM-10 models except those
using 240 V, three-phase power with SSR control.
SDU-E:
For higher capacity units
The Space Distribution Unit External Absorption
(SDU-E) is designed for higher capacity dispersion.
The SDU-E is available for all VAPORMIST models
except those models using 240V/480V/600V/three-
phase power with the SSR control option and drawing
more than 21.7 amps.
Mounting the SDU-I and SDU-E
Both SDUs may be mounted on a wall directly above
the VAPORMIST cabinet or mounted on a wall remote
from the VAPORMIST. Use the mounting template on
the box for correct placement. Two lag bolts are
provided with each fan unit.
Note: See the following pages for more information
about SDU-I and SDU-E.
The SDU can be mounted remotely
from the VAPORMIST.
