YORK® CEILING AND INLINE CENTRIFUGAL FANS, CI-SERIES
5
Low Sound
For sound critical applications, S type fans delivers the lowest
sound ratings. All units feature acoustically insulated housings,
custom designed blower and motor pairings, motors mounted on
vibration isolators, and for all but the smallest model (CI3H), dual
inlet blowers.
High Static Pressures
When higher static pressures are encountered, the H type fans
excel. Faster RPM allow these fans to better sustain airflow as
static pressure increases. This makes them well suited for inline
applications.
Housings
Housings are fabricated of galvanized steel. Acoustical
installation is used to minimize sound.
EasyTap Speed Selection
Select models (CI6S/H, CI8S/H, and CI10S/H) are provided with
dual speed motors designed to run at nominal speeds of 1050
and 1550 RPM. By simply changing one wire tap, a fan’s speed
can be switched. This ability to alter speed and air flow allows
on the spot adjustments to deal with unforeseen circumstances.
Systems deficiencies can be accommodated in the field quickly
and without the added cost of replacing a fan.
Motors
All units have permanently lubricated motors manufactured
to our exacting specifications. Motors feature built in overload
protection and plug in disconnects.
Grilles
Constructed of attractive molded white plastic, aerodynamically
designed grilles feature an 85% free area. To make for easy
removal and cleaning, the grilles are held in place with spring
clips. An optional metal face grille with a white finish is available.
Wheels
Wheels are dynamically balanced and performance matched
with the motor. On units CI5H and larger, dual inlet blowers are
employed to minimize sound levels.
Quick Access Wiring
Access to the motor leads is through a panel in the side of the
unit; there is no need to remove the power pack. However, if the
need to remove the power pack ever arises, a quick connect plug
makes the process simple and easy.
Field Conversion
The CI-Series cabinet is designed for quick transition from right
angle discharge to top discharge or into an inline configuration.
Simply remove two (or four depending upon model) sheet metal
screws, switch positions of the access panel and top panel,
re-attach screws, and a right angle discharge becomes a top
discharge fan. There is no need to remove the power pack. The
blower remains oriented in one position while the panels change
places. The transformation to an inline fan is accomplished by
the replacement of the grille with an access panel. Again, only
two (or four) screws are involved in the process.
