IMPORTANT SAFETY NOTICE
Terra Universal cleanrooms are not designed to support more weight than the blower modules and
lighting fixtures originally installed. Ceiling grid beams are not load-bearing and will not support personnel or
other additional loads. Placing added weight on the ceiling grid may result in serious damage to the cleanroom
and its occupants.
Safety notices supplied by Terra Universal must be affixed prominently on each side of the cleanroom
grid.
1.0 Description
Terra Universal’s Softwall Modular Cleanrooms provide an
economical, versatile solution to clean manufacturing requirements
in many industries. Portable, expandable, and easy to
assemble/disassemble, this system features ceiling HEPA fan filter
units that direct a continuous flow of particle-free air through the
enclosure. It is completely free standing and requires no external
bracing.
Frame
This system consists of a steel support frame, ceiling mounted
filtration and illumination system, flexible side panels and a variety
of other access options.
The softwall cleanroom support frame is fabricated of interlocking 2.5” powder-coated square steel or stainless steel uprights,
cross sections, and ceiling members.
Ceiling members are connected to steel T-bars, forming the 2’ X 4’ bays that support filters and lights. Corner reinforcement
gussets ensure a rigid structure. Optional heavy-duty casters allow easy repositioning after installation. Standard height is
seven feet measured from filter face to floor (8’ 3” overall), allowing installation below a standard nine foot ceiling. Custom
ceiling heights up to ten feet are available. System includes a control panel for operation of fan filter units, lights, and other
selected options.

Fan Filter Units (FFUs)
FFUs direct a vertical laminar flow of filtered air downward through the enclosed cleanroom area.
Each includes a built-in motor and impeller, mounted in an aluminum housing with a plenum design that ensures
ample air velocity across the entire face of the filter. A HEPA (high efficiency particulate air) filter installed inside the
housing is rated 99.99% efficient at 0.3um particles. The filtration medium consists of micro porous polyurethane
mini-pleats held in place by strong, rigid plastic separators that keep the medium from nesting. This design channels
airflow with optimal efficiency to reduce resistance. The filter is sealed into the sturdy powder-coated steel frame
with a fire-retardant, non-outgassing adhesive. On an optional basis, an ULPA (ultra-low penetration air) filter, rated
99.9995% efficient at 0.12um particles, may be substituted for the HEPA filter. Power to the Fan Filter Units is
controlled by a master ON/OFF switch located on the cleanroom control panel. All 120VAC units and 220VAC, 60Hz
units are UL listed. CE-marked models are available for 220VAC, 50Hz operations.
Recommended Qty of FFUs to meet Cleanliness Classifications (based on ceiling height of 8 feet or less):
UL Label: If your order included UL documentation (Cat. # 6600-33), your cleanroom will include labels indicating
the use of UL-listed components on one of the triangular gussets (see below photo).

Light Panels
Each light panel is externally mounted to ensure effective illumination of the work area
without interfering with the controlled air stream. Each module is controlled by a
master switch mounted on the main Cleanroom Control Panel.
Cat. # 3800-41B
Power Requirements
USA: 115VAC/60Hz, 1.50A Each
International: 277VAC/50Hz, 0.65A Each
Blank Ceiling Panels
All remaining ceiling grids are covered with blank panels, which can be removed to allow installation of additional
fan filter units or illuminator modules. Panels are made of white polypropylene, acrylic or steel depending on
customer selection. All ceiling modules rest against the ceiling grid frame to form a tight seal along the perimeters.
Softwall Panels & Strip Shields
Softwall panels are fabricated of heavy-duty, blur-free 40 mil, vinyl or polyurethane—double the industry standard—
ensuring enhanced tear resistance and eliminating the need for unsightly sewn sash weights. Strip shields, made
of 60-mil material, come standard in 8” widths, with 2” overlap, for easy entrance or exiting. Polyurethane shields
are 12” W, 40 mil thick.
Panels and strips are available in three materials, in either clear or frosted
appearance.
Cleanroom-Grade Vinyl is fire retardant and low outgassing
Static-Dissipative Vinyl is manufactured with permanent built in
static inhibitors that unlike topical treatments, will not wear off.
Non-outgassing panels are made from inherently static-
dissipative polyurethane that provides permanent, humidity-
independent ESD protection for sensitive manufacturing
conditions. Polyurethane contains no plasticizer, making it
virtually non-outgassing.

Note: Softwall panels are notched to ensure a snug fit at all corners. In standard installations, panels are supplied
in lengths of four feet. Where two panels meet, the panels overlap by 6”. To prevent personnel from parting panels
at these seams, order optional panel seaming, Dual-Lock Velcro, magnetic closures or attachment clips below.

Casters
Stainless steel swivel casters feature non-shedding polyurethane wheels. Capacity: 300 lbs. each.
Order one per vertical post. Casters raise the frame 7.125". If casters are ordered, the frame will be
made shorter to keep the floor to filter face dimension to specification. Order one per vertical post.
Cat. # 6704-08
Caution: Casters are intended to allow movement only on smooth floors and require that personnel
support each cleanroom upright during motion.
2.0 Installation
Unpack all system components and check for damaged. Any damage should be reported to the shipping company
immediately.
Site Preparation
A. Site preparation requirements should be observed for any installation performed by Terra Universal
technicians.
B. Customer facility area where the cleanroom is to be installed must afford a minimum clearance of one foot
(including fixtures ducts and pipes) on all sides and at least two feet clearance between FFU inlet and ceiling.
C. Customers must provide permanent electrical connection from supply panel to Terra Cleanroom electrical
junction boxes (one power line per junction box) in conformance with local electrical code, as well as any
vacuum, air, H20, sprinkler, or nitrogen connections required for the cleanroom.
D. Customers must give advance notice of dates and times for Terra personnel to perform the installation. Short
notice may result in higher fees for travel and accommodations.
E. Customers are to provide utilities, installation power and removal of any packing material.
F. Because installation requires unpacking and assembling components, customers are to ensure an adequate
staging area for parts and equipment adjacent to the assembly area, clear and ready for work.
G. Customers are to inform Terra Universal in advance of any requirements for security, escorts, special training,
badges, work hours, parking areas or special identification and how to obtain all such required permissions
and related items.
Required Installation Equipment
A. Handling cleanroom shipping crates, which generally measure over 300” long and weigh well over 1,000
pounds, requires at least one forklift. If crates must be moved through narrow aisles or entrances, two forklifts
or pallet jacks are recommended, one to support each end.
B. Unloading crates from the truck is much easier if you have a truck-high loading dock. Without such a dock, you
will need at least one forklift and a support to brace one end while the forklift is positioned beneath the center
of each crate. Several men are required to unload individual components from the crates.
C. You’ll need heavy rubber hammers, good portable drills/screwdrivers, measure tapes (to make sure
everything’s square) and six to ten 11” locking C-Clamps used to hold beams in place as you insert fasteners.
Another tool that will be needed is an 8” – 12” shaft extension for the screwdriver bits (to drive screws in narrow
gaps between parts).

Frame Assembly
Installation Note: Before beginning installation of the support frame, familiarize yourself with the placement of
the frame members.
IMPORTANT SAFETY NOTICE
Terra Universal Cleanrooms are not designed to support more weight than the blower modules and lighting
fixtures originally installed. In particular, the ceiling grid beams are not load bearing and will not support personnel
or other additional loads. Placing added weight on the ceiling grid may result in serious damage to the cleanroom
and its occupants.
Safety notices supplied by Terra Universal must be affixed at appropriate places on each side of the
cleanroom grid.
Prior to shipping, all frame and ceiling members are stamped and then labeled at each end. Refer to the appendix
for detailed information on how your cleanroom is numbered.
Before you start assembly, it is mandatory that the floor is level to assure the completed room will fit properly and
be rectangular. Failure to level the floor may result in the inability to complete the assembly of the room or the
insertion of the blowers, lights or ceiling. For vertical alignment, measure with the leveler before assembly.

Seismic Anchoring
Because most Softwall Cleanroom models have custom configurations, the number of screws required for seismic
anchoring will vary based on the size of the cleanroom. Each post on the frame has a foot with four pre-drilled holes.
Be sure to adhere to local seismic codes when anchoring the cleanroom. Terra recommends drilling 6” deep and
placing a 3/8” Kwik Bolt TZ (not included) anchor for a minimum embedment of 3-5/8” in each of the foot’s holes. This
is an example, but local seismic codes may vary.
