Terra's Portable CleanBooth™ provides a mobile, versatile mini-cleanroom wherever you need it! It is ideal for operations with probe stations, screen printers and other free-standing process equipment, as well as benchtop kitting or assembly.

FFU: Quiet, Reliable Operation

It consists of two modules: a fan/filter unit (FFU), which houses a particle filter, and a mobile support frame. The 2' x 3', 2' x 4' or 4' x 4' FFUs house a HEPA filter, rated 99.99% efficient with 0.3 micron particles. Fan/filter units come with brushless AC motors or low-energy EC (electrically-commutated) motors that comply with energy-efficiency standards. The lightweight design of Terra's FFUs make them ideal for mounting either to the mobile frame or to any standard 2' x 4' (610 mm x 1219 mm) ceiling grid. An internal baffle system ensures uniform face velocity, and the 50 dBA noise rating is the best in the industry.

Fan/filter units add 13 inches to the overall height of portable CleanBooths.

Mobile Frame Support

The FFU is attached to a castered support frame for easy positioning at locations throughout your facility.

Fabricated of 1" x 2" (25 mm x 51 mm) square steel powder-coated members, it positions the filter face 70"(1778 mm) (or 83" (2108 mm) for 4' x 4') above the floor. The nonmarking castered wheels lock in place to keep the station where you need it. Its sturdy construction safely supports the FFU with minimal vibration. And because the frame does not come in contact with the bench top or service equipment, the blower vibration is effectively isolated from the work-in-progress.

Flexible Side Panels Restrict Air Flow to Optimize Cleanliness
For enhanced laminar flows, select the optional side panels, available in three materials:

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 Polyurethane is made from inherently static-dissipative polyurethane that provides permanent, humidity-independent ESD protection for sensitive manufacturing conditions. Polysim contains no plasticizer, making it virtually non-outgassing.

Side softwall panels attach to the FFU by means of a unique, noncontaminating Grip-Track™ mounting system that eliminates cracks and seams where germs or particles can collect.

Side Softwall Panel Kits
Includes curtains of specified material that attach to the FFU. Kit catalog number includes installation of Grip-Track mount on two sides and rear of FFU. Panels can be cut to bench level.

Work Benches

These benches have adjustable legs for work-surface heights of 25" to 34" above the floor. Several surface materials are available to meet specific applications. The epoxy-finished steel frame includes a stainless steel scuff guard on the lower leg member to prevent scratching and chipping.
