Laminar Flow Cabinets

This HEPA-filtered cleanroom storage cabinet features heavy-duty vertical locking rods to prevent unauthorized access. SDPVC windows provide visibility and perforated stainless steel shelves are adjustable in 0.5” increments for greater space efficiency.

HEPA-filtered vertical laminar airflow storage cabinet provides a Class 100 (ULPA for Class 10) particle-free environment for curing or storing sensitive components like optical assemblies. Perforated shelves allow vertical laminar flow through the cabinet.

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.

Non-uniform air speeds produce turbulence that can recirculate particles into the air stream. Unique WhisperFlow® FFU baffling system and anodized diffuser plate promotes uniform laminar airflow to minimize turbulence and effectively carry away contaminating particles.

HEPA and ULPA filters help capture many bacteria, viruses (COVID-19), and mold spores that contribute to a host of infections for both humans and plant/animal tissue cultures

Exposure to loud noises can lower the ability to focus on work and listen selectively, which may also lead to safety issues. Typical AC units can be annoyingly loud, measuring in the range of 70 dB (comparable to a vacuum cleaner). 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 (roughly 75% quieter than 70dB).

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.

Economical ValuLine™ laminar flow storage cabinets provide a ISO 5 (Class 100) positive-pressure, particle-free environment for drying or storage of contamination-sensitive materials. The transparent plastic design provides full visibility to easily find or monitor stored items.

The fan-filter unit mounted on top supplies single pass HEPA-filtration, pressurizing the cabinet’s interior to protect against particle contamination. Doors for each chamber reduce in-flow of outside air and contaminants during material transfer.

Slotted chambers help quickly circulate and mix clean air throughout the cabinet to minimize “blind spots” and further dilute particulates inside the cabinet. The bottom doors of the cabinet have air exhaust vents to promote vertical laminar airflow.

Stainless steel reinforcing bar provides added rigidity and durability to plastic doors.

Closed-cell door gasket maintains internal positive pressure when purged with dry gas, and stainless steel reinforcements extend door life

Terra's SDPVC features bonded dissipative layers that resist abrasion. SDPVC desiccators retain their surface resistivity of 106 - 108 ohms/square indefinitely (unlike spray-on coatings that can wear off after a few years), protecting your materials against ESD damage. Further, the control of static charges eliminates particle attractions, helping maintain clean surfaces.

Self-closing 316L stainless steel hinges use springs to both hold open and help tightly close doors. Stainless steel drastically extends service life and minimizes corrosion, flaking, and contamination that commonly occur with ordinary chrome-plated hinges.

Swell latches open/close with the flick of a finger to save wrist strain. An expanding rubber bushing firmly seals doors to prevent dust and moisture from leaking in, plus eliminates corrosion, flaking, and particle contamination from chrome-plated latches.
