Features and Benefits

Valuline vs. Standard Cleanrooms

How are Terra Universal’s ValuLine and standard cleanrooms different? Is the standard line cleaner?

Ordering Information

Both cleanroom lines meet the same quality standards for design and materials while also providing essentially the same airflow, which is based on the configuration of fan/filter units.

However, Terra’s standard cleanrooms utilize Power Distribution Modules, which can accommodate more FFUs and light fixtures than the basic power supply included on ValuLine cleanrooms. PDMs also feature quick-connect fittings and a better control panel. ValuLine cleanrooms do not include the decorative top trim and status indicator lights included on standard line cleanrooms.

Each standard line cleanroom is built-to-order, can be made in virtually any reasonable size and can use alternative materials such as stainless steel frames. ValuLine cleanrooms are preconfigured from standard components to produce ten standard sizes from 6’ x 6’ up to 12’ x 12’ in each of two heights (7’ and 8’), allowing shorter lead times.

WhisperFlow® Cleanroom Fan Filter Units

Design features internal baffling and an aluminum diffuser to provide quiet operation along with uniform air speed for ISO-compliant laminar flow.

Aluminum Frame Swing Door

Light-weight, easy to install, and includes concealed pneumatic door closer.

Cleanroom LED Light Panel with Emergency Power Supply, 2' x 2'

Cleanroom LED lights are equipped with emergency back-up batteries to ensure continued operation in the event of a power failure.

Cleanroom LED Light Panels

LED panels mount flush on ceiling grid, have longer life, are more energy efficient, and emit less heat than conventional fluorescent lights.

Long Running FFU Motors

Terra’s filter fan unit motors are rated for 5 years of continuous, 24/7 operation, if the HEPA filters are consistently replaced. To accurately monitor your HEPA filter’s saturation levels, purchase Terra’s audible and visual filter replacement alarm system.

Clean and Durable Powder Coat Finish

Terra’s signature white powder coat finish provides a high quality, durable barrier to protect against corrosion, plus a clean and attractive aesthetic. The advanced heat-fused formulation exceeds ASTM and ISO paint standards to resist chipping, scratching, fading, and wearing.

WhisperFlow Quiet Operation Reduces Distracting Background Noise

Exposure to loud noises can lower the ability to focus on work and listen selectively in conversations. Typical AC units measure ~60 dB at 100 ft. Terra’s WhisperFlow design produces far lower noise levels for a quiet environment comparable to a library. At 90 ft/min output, units measure under 50 dB from only 1 ft away.

Highest Standards For Electronic Components

Terra’s electronic components are designed and built to the highest standards required by defense and semiconductor industries for long-term reliability and protection against damage, injuries, and electrical hazards.

Seismic Safe Cleanroom Design

Terra’s modular cleanrooms are designed with seismic safety in mind. Rigid steel frames and ceiling grids are designed with sufficient factors of safety to provide vertical and lateral strength recommended by professional engineers. Both hardwall and softwall designs can be installed to adhere to local seismic codes. Optional seismic and structural calculations can be drafted and stamped by a licensed PE to help meet municipal permitting requirements.

Continuous Product Improvement

At Terra, we strive to develop and produce the highest quality products for our customers to improve health, safety, performance, and yields. We accomplish this by harnessing high-grade manufacturing equipment and processes, 45 years of engineering and application expertise, and our will to continuously improve.

High-Throughput Cleanroom Manufacturing

Over the past 5 years, Terra has manufactured nearly 1,500 UL-approved cleanrooms at industry-leading build times. Terra’s versatile modular cleanroom frame and panel designs adapt to any floor plan requirement. The UL-rated and scalable plug-and-play power distribution system further simplifies installment of FFU's and lights to cleanrooms of any size.
