Features and Benefits

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.

HEPA Fan Filter Unit with Integrated LED Light and Ionizer

FFU with built-in, flush-mount LED and ionizing bar provides HEPA filtered air and neutralization of static charges. Eliminates hard-to-clean, exposed light fixture and ion bar. Includes internal baffling plate and diffuser panel.

Recessed Lighting and Optional UV-C Sterilization

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

Touchscreen Control Panel

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

Room-Side Replaceable HEPA Filter

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.

Vertical Flow of HEPA-Filtered Air Meets ISO 5 Particle Requirements

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

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

Integrated Stands Isolates Hood from Work Surface

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).

WhisperFlow Quiet Operation Reduces Distracting Background Noise

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).

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.

Complete Project Transparency

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

ISO 5 Vertical Laminar Flow Clean Bench with Automatic Height Adjusting Table

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.

  • UV Germicidal Lamp

    The V-Ray germicidal UV lamp is installed within a Terra hood to inhibit microbial growth on the work surface
  • Static-Neutralizing Ionizing Bar

    Airflow from the blower distributes positive and negative ions onto the surfaces below, neutralizing static charges that can lead to electro-static discharge and attract particles.
  • Replacement Filters

    Purchase replacement filters ahead of time to prevent costly operational interruptions and avoid damage to fan blowers caused by excessive backpressure from long overdue filter replacements.
  • Lighthouse Handheld Airborne Particle Counters

    Lightouse portfolio of handheld airborne particle counters ensure accurate readings of cleanrooms and critical environments
  • Isolated Work Surfaces in Many Materials

    Tables in many styles and materials, including dissipative laminate, chemical-resistant polypropyene and epoxy resin, are isolated from hood to reduce vibration (shown: solid stainless steel top with adjustable powder-coated legs).
  • Work Station Drawers

    Available in ABS plastic or stainless steel, these cleanroom-compatible drawers come in a number of sizes and drawer configurations (6” top drawer and 6” bottom drawer shown).
  • Explosion-Proof Fan Filter Unit for Hood

    UL-listed, NEC Class I, Division 1 Explosion Proof fan/filter unit provides HEPA filtration where solvent vapors, dust and other flammable hazards are present; all conduit and switches also meet explosion-proof requirements.
  • Explosion-Proof 40W LED Light

    UL-listed for Class I, Division 1 and 2, Groups C and D areas, this low profile LED light produces 3,600 lumens and operates from 120 to 277VAC, 50/60Hz. The heat-dissipating housing increases the efficiency and lifespan of the LEDs.
  • Explosion-Proof Power Switches

    UL-rated explosion-proof switches are connected to the lights and blowers using specialized conduit with potted fittings. All electrical components are sealed to eliminate potential ignition points.
