Product Information
Design Objectives
Unitee CR Series was developed to provide
the market with an attractive, functional
ceiling system that prevents air leakage
between the ceiling plenum and the
occupied space below, thereby pre­venting
the flow of contaminants into or out of the
clean zone.
Hold-down clips press each ceiling panel
tightly onto a special white vinyl gasket
that is an integral part of the ceiling grid
suspension members.
The entire ceiling, or any part of it, is easily
removed and reinstalled, providing access
to mechanical and electrical equipment or
for cleaning the space above the ceiling.
Applications
Unitee Cleanroom Ceilings can be used
for pharmaceutical labs, computer chip
and electronics manufacturing, hospital
laboratories, isolation rooms and hospital
operating rooms - any situation demanding
strict clean air control.
Fully Accessible
A major feature of Unitee CR Series is that
it can be easily removed and reinstalled,
providing access to the plenum space.
Occasionally mechanical or electrical
equipment fail, requiring large areas of the
ceiling to be removed. Some applications
require that the entire ceiling be removed
for cleaning the plenum space above the
ceiling. Unitee CR Series uses the Price
two-piece Universal Assembly Clips, which
allow the grid to be easily removed and
reinstalled.
Finish
The standard finish for Unitee CR ­Series is
B12 White Powder Coat.
Other finishes are available upon request.
Ceiling Panels
Painted metal panels are available to suit
the application. Panels can be specially
designed to accommodate sprinklers, gas
columns and other penetrations.
Features/Benefits
The hospital operating room shown above has Price HORD and LFD air diffusers integrated
into the system. Integrated systems have the advantage of providing single source
responsibility for component performance and for the proper interface of individual
components.
• Entire ceiling is easily removed and
re-installed, providing easy access to
mechanical and electrical equipment
­
in the plenum. Ceiling plenum can be
easily cleaned by removing part or all of
the ceiling system.
• Design flexibility - several profiles to
choose from, any module size ­available.
• Extruded aluminum construction for
clean, crisp lines, maximum durability
and rust-proof performance. Choice of
painted or anodized finishes.
• Integral vinyl gasket prevents air leakage
between the plenum and occupied
space.
• Steel hold-down clips secure the ceiling
panels tight to gasketed grid member.
• Unique grid connector clips facilitate
rapid ceiling installation and allow
ceiling members to be easily removed.

Components
The Unitee CR series comes in four standard
tees and one wall mold.
#4806 Is a 11/2 in. wide T-bar. The heavy
duty T-bar is 115/16 in. high and is complete
with an integral vinyl gasket and the
provision for installation of hold-down clips.
#4730 Is similar to the #4806 in
construction, but is only 11/4 in. wide.
#4732Is also similar to the
other cleanroom T-bar, but is only
1 in. wide. This is the most common
cleanroom tee as wider faces may prevent
lights and diffusers from opening.
#4726 Is a 11/4 in. cleanroom T-bar that
incorporates a threaded slot.
#4733 Is the cleanroom wall mold. The
gasketing is located so that the tee is sealed
at the wall as well as the ceiling panels

CRITICAL ENVIRONMENTS
Is a ceiling panel with B12 white powder
coat finish. The SC series panels allow the
ceiling to have the same durability as the
T-bar and accommodate easy cleaning. The
SC panel can be ordered with an access
door (AD option). The access door features
quarter-turn fasteners to provide an opening
for service or removal of clipped in panels.
SPB
Is a perforated-face ceiling panel that has
a sealed backpan. The SPB gives the same
appearance as a laminar flow diffusers.
Standard finish is B12 white powder
coat. The panel is available with 51%
perforation to match Price HEPA filtered
diffusers, 23%, or with 13% to match Price
non-filtered diffusers. The SPB panels are
also available with an access door (AD
option).
SC and SPB panels are available in aluminum
and stainless steel. SC and SPB panels
are available with quick-connect locking
clip that locks the panel hold-down clips
to the panels to prevent them from being
misplaced during maintenance routines.
Hold-down clips are shipped loose and
locked in place in the field.

System Details
Integration
The Unitee CR Series ceiling system can be combined with Price diffusers such as the laminar flow diffuser (LFD), radial flow diffusers
(RFD, FRFD), hospital operating room diffusers (HORD), fan filter units (FFU) and lighting fixtures (by others) for an integrated package.
Integrated systems have the advantage of providing single source responsibility for component performance and for the proper interface
of individual components.

Ease of Installation
The Unitee CR Series assembles quickly by means of a patented two-piece Universal Assembly Clip that consists of a steel mounting
clip and spring steel locking clip, both of which are normally factory installed on cross tees. Each Universal Assembly Clip has a bayonet
end which is designed to pass through the regimentation holes in the main tee members and lock securely in place. Regimentation
holes are the paired holes punched in the stack of the main tees that allow for connection of a cross tee. These are spaced as required
to suit the reflected ceiling plan.
Splice plates, also known as butt end clips, are used where two tees butt together to form a longer tee section. These butt end clips are
not factory installed, but are instead packaged separately.
The speed of installation with this design helps reduce installation cost, and assures better alignment and a more rigid installation. If it
becomes necessary to remove a part or the entire ceiling, simply remove the locking clips and the grid members will easily disengage
from the ceiling. The end result, Unitee CR Series is effective and functional
for applications demanding strict cleanliness.
