Hoods 101

Laminar Flow and Fume Hoods 101

Laboratory hoods serve a number of critical purposes in the modern lab environment.

Product protection from particulate contaminants in the lab environment, including microbes

Such hoods, often called laminar flow workstations or clean benches, use a flow of micro-filtered air to prevent influx of particles into the enclosure and to sweep away any contaminants generated by the work process.

Protection of personnel and lab environment from substances generated inside the enclosure

For fume containment, laboratory fume hoods use a ducted ventilation system that maintains negative pressure. Where ducting is impractical, ductless hoods are also available for removal of non-hazardous contaminants (fumes or particles), using either HEPA or activated carbon filters.

Protection of both product and operator and environment

Biological safety cabinets combine aspects of both hood types: a laminar flow of micro-filtered air and negative-pressure containment of hazardous fumes.

Laminar Flow Hoods

Laminar flow hoods (also called clean benches) force air through a HEPA or ULPA filter to create a clean work area free of nearly all contaminating particulates, including bacteria, mold spores and many viruses. These hoods use a vertical or horizontal airflow design. Both provide excellent protection of products from particulates and cross-contamination, but do not protect the operator or environment.

So why choose one over the other? Vertical laminar flow (VLF) hoods require less floor space, but more overhead clearance. In addition, a sash at the front of the VLF hood provides a barrier between air exiting the hood and the operator’s face. VLF hoods create turbulent air flow when air strikes the work surface, requiring sterile work to be performed above the work surface.

HLF hoods minimize air turbulence (and particle backflow) on the work surface except where equipment disrupts the horizontal airflow. However, they direct the airflow directly at the operator’s face and require more depth to accommodate placement of the fan filter unit at the rear of the hood.

Fume Hoods

Laboratory fume hoods draw air from the environment into the opening of the hood, allowing environmental contaminants into the work area. Thus, fume hoods do not offer a sterile environment or product protection. Instead, fume hoods are designed to protect the operator from dangerous or irritating fumes and powders generated from work done inside the hood.

In ducted fume hoods, air passes out of the hood through a duct leading to in-house ventilation system that contains and/or neutralizes hazardous materials.

In ductless fume hoods, fans draw exhaust through a series of filters that remove irritating substances and then release it back into the room. Since these filters are not 100% efficient in removing all substances, ductless fume hoods are not advised in the presence of biohazards; however, they provide a convenient, cost-effective solution for operations involving irritating but non-hazardous fumes in facilities where an in-house HVAC system cannot be accessed.
Biosafety Cabinets

Biosafety cabinets combine aspects of both laminar flow and fume hoods. Filtered air is directed downward onto the work surface and then travels into a plenum through openings on the front and sides of the hood. Depending on the classification of the biosafety cabinet, some percentage of air is recirculated and the rest is directed out of the hood through an exhaust system. Thus, biosafety cabinets offer both operator and product protection.

These hoods are ideal when working with sterile substances such as chemotherapeutic agents that may pose a risk to the operator.

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).

Recessed Fluorescent Lighting

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

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.

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

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.

  • 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.
  • 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.
  • HEPA Filter Capture Micro-Contaminants
    HEPA (High-Efficiency Particulate Air) Filters rated 99.99% efficient with particles 0.3 microns and larger in diameter.
  • 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.
  • 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/12” bottom drawer shown).
  • 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).
