Modular Hardwall Cleanrooms

Modular Hardwall Cleanrooms provide the rigidity and durability of a freestanding room. All components are factory-assembled and tested before shipping; the modular ceiling grid allows fan/filter configuration to meet ISO 5 – 8 requirements.

Unlike other modular cleanrooms on the market which require complex suspended ceiling supports, Terra Universal cleanrooms are completely free-standing structures.

Cleanroom Support Frame

The support frame is fabricated of interlocking 2" (51 mm) powder-coated square steel uprights and cross sections. Ceiling members are welded to steel 3" x 1.5" (76 mm x 38 mm) T-bars, forming the 2' x 4' (610 mm x 1219 mm) bays that support filters and lights. Standard height is 7' (2134 mm) measured from filter face to floor (8'3", 2530 mm, with filter/fan unit), allowing installation beneath a standard 9' (2743 mm) ceiling. Other heights are available.

Hardwall Cleanroom Panels

Modular hardwall panels are cut in 4'-wide x 7'-high (1219 mm x 2134 mm) panels. Specify other desired height. They are available in several rigid materials:

Acrylic Panels offer full visibility and outstanding tensile strength. These economical panels are lightweight and easy to clean. Standard panels are clear, but black and amber panels are also available (tinted panels may extend lead time). Acrylic is not recommended for use with alcohol or other strong cleaning agents.

Static-Dissipative PVC Panels are recommended for the most contamination-sensitive applications because of their ability to control particles along with static charges. The friction created by a laminar airflow generates surface charges on nondissipative walls, which in turn attract and hold particles. Your cleanroom wall becomes a particle magnet!

Dissipative PVC safely conducts these surface charges to ground, protecting against potentially damaging ESD (electrostatic discharge) as well as particulate contamination. Dissipative layers are molecularly embedded for optimal durability. Surface resistivity: 106 - 108 ohms/sq. cm (ASTM-D257).

Polycarbonate resists many common acids, solvents and cleaning solutions. Its high tensile strength makes it shatter resistant.

Polypropylene provides superb resistance to acids and other chemicals.

Tempered Glass combines visual clarity with broad chemical resistance and non-porous surfaces for easy sterilization.

IsoVent™ Air Release Vent
Each of the standard plastic panels features a series of exhaust vents, covered by a flexible static-dissipative PVC strip to prevent particulate influx. These IsoVents ensure adequate positive pressure inside the enclosure, independent of filter configuration.

Hardwall Cleanroom Options

Night Service Switch

  • Energy-saving mode saves 25% of fan operating costs by reducing power consumption during off-hours
  • Maintains round-the-clock cleanroom integrity at lower cost
  • Easy to activate via panel-mounted switch (Wireless Cleanroom Control System also available)

Why Pay More for Less?
Terra cleanrooms are designed to meet a specified ISO cleanliness rating when a cleanroom is in use: with operations in progress, process machinery humming, and personnel in motion. So why pay to maintain that level of FFU performance when a production shift ends and people, the greatest source of contamination, leave the room?

With a greatly reduced contaminant load, a cleanroom at rest maintains its target ISO cleanliness standard with much less airflow, fewer air changes—and decreased power consumption. Terra’s Night Service Switch provides this cleanliness at a nominal cost, giving you immediate cost savings.

Simply select the “Night Service” Switch when you turn off the lights and go home. A separate operation circuit drops all Fan/Filter Units (FFUs) into low-energy operation mode, shaving 25% of energy costs off your power bill while maintaining uninterrupted cleanroom performance at your specified cleanliness level. With Terra's Night Service Switch, operators can save up to 7,000 kilowatt-hours per year with a return on investment in slightly over a year.**
Ordering Information
A complete system includes fan/filter units and Terra's standard Power Distribution Modules (order separately), in addition to the units specified below. The Night Service Switch includes electronic configuration of each FFU controlled by this system. The Control Panel includes switch settings and indicator lights for Normal Mode and Night Service Mode, as well as a tamper-resistant master FFU Off switch.
