Installation of the Cool-stack II rack-mount ventilator
The Cool-stack II is a very powerful 2U high ventilator, well-suited for removing
heated air from large rack installations. Some of the features of the Cool-stack II
are:
Two-speed operation, with automatic selection of speeds via a thermal probe
and control assembly; also controllable by external contact closure.
Sufficient depth (18") to pull heated air from the back of a rack, where it is
most often generated.
Six large (120mm/4.7") high-quality fans for quiet ventilation.
Ability to exhaust heated air through the front, rear, or top, or any combination
of these for maximum installation flexibility. (With optional exhaust kits)

General description:

The Cool-stack II is an exhaust-mode ventilator. It will usually be located at the
top of a rack, where its six 120mm fans will pull heated air up from the equipment
below and exhaust it through its front panel. It is extremely quiet in low speed,
and makes little noise in full speed.
