Hoods for Wet Processing
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.
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).
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, 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).

UV Germicidal LampThe V-Ray germicidal UV lamp is installed within a Terra hood to inhibit microbial growth on the work surface
Static-Neutralizing Ionizing BarAirflow 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.
HEPA Filters Capture Micro-ContaminantsHEPA (High-Efficiency Particulate Air) Filters rated 99.99% efficient with particles 0.3 microns and larger in diameter.
Lighthouse Handheld Airborne Particle CountersLightouse portfolio of handheld airborne particle counters ensure accurate readings of cleanrooms and critical environments
Isolated Work Surfaces in Many MaterialsTables 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 DrawersAvailable 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 HoodUL-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 LightUL-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 SwitchesUL-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.
