Vertical Laminar Flow Hoods

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.

Included recessed light fixture simplifies cleaning and minimizes airflow disruptions (shown next to optional UV sterilization bulb).

PLC control panel provides control of fan speed, lights, and motorized shield; digital gauge monitors backpressure and issues alerts when filter(s) need replacement

To simplify filter replacement, HEPA filters can be removed and replaced while the FFU remains installed; the gel-sealed filter seats securely against the "knife-edge" on the blower housing to form a tight seal.

Side panels and access shield optimize unidirectional flow of HEPA-filtered air; advanced baffling technology ensures uniform face velocity to meet ISO 5 particle requirements.

Motorized access shield, included on select models, enhances laminar flow and protects operator from chemical fumes and other environmental nuisances.

Built-in stand with dissipative PVC side panels allows VLF Stations to be positioned over any table or processing equipment without transferring hood vibration to work surface (shown integrated with optional modular wet station).

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 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.

Terra is dedicated to complete transparency on project status, shipment tracking, and installation scheduling

Automatic height adjusting tables fit perfectly inside free-standing laminar flow clean benches. The separate workstation helps isolate vibration from the fans mounted above the hood. Dual motor electric height adjusting columns beneath the table allow users to quickly raise or lower the work surface without moving equipment off the table.
