Laminar Air Flow
Horizontal Laminar Air Flow
Room air (in red) enters the system from behind the HEPA filter; 99.99% particle-free air is forced in a back-to-front direction across the work surface.
Although both airflow designs provide effective sweeping action near the filter face, their respective flow patterns eventually encounter disruptions that often tip the scale in favour of one or the other configuration. In a vertical-flow hood, the obvious obstacle is the work surface. A perforated or rod-top work surface allows the laminar air stream to pass through the hood with minimal obstruction, but these tops can be a problem in operations involving liquids or small parts. If you’re working with these materials and want to avoid picking up parts off the floor, a horizontal flow design may be preferable.
Yet even a solid top may not rule out vertical flow if work is performed above the work surface. If sterile or particle-sensitive processes are performed in a clean, sterile zone midway between the work surface and the filter face, a vertical flow hood is generally acceptable. One such operation is sterile compounding, in which injectables or sterile packages are prepared above, not on, the work surface. As long as hands and other contamination sources move up and down, not sideways above a sample, sensitive materials will remain clean.
Finally, consider the effects on operators of air exiting the laminar flow hood. Although horizontal laminar flow, with air traveling from the rear of the hood and exiting the front opening, may not encounter large obstructions inside the hood, it does eventually encounter the person performing the work. Any annoying substances, such as soldering fumes or fine powders, may be blown into the operator’s face. While this collision may not compromise the laminar flow where work is performed, it may pose a health risk. In such cases, vertical flow is probably preferable.
Vertical Laminar Air Flow
Room air (in red) enters the system from above the HEPA filter; 99.99% particle-free air is forced downward toward the work surface.
A clean bench using a vertical laminar flow design is also preferable where floor space is at a premium. Because this configuration stacks the fan/filter module on top of the hood, a vertical laminar flow hood can generally be installed on a standard lab bench. By contrast, a horizontal-flow hood requires additional depth to accommodate the rear-mount filter/fan unit with some additional rear clearance to allow air to enter the system. These clearance requirements necessitate a deeper bench and more floor space than a vertical flow system.
Biosafety Cabinet
Biosafety Cabinet Class I
Class I BIOSAFETY is designed for operator and environment protection from hazardous materials and substances for operator's health. The operation is based on the forced removal of hazardous substances from the working zone through the air up-flow, with high-effective air filtration and exhausting the air into the environment. Due to the unidirectional laminar air flow, there is no risk of their cross-contamination when there are more than 2 agents working on the equipment.
Biosafety Cabinet Class II - A1 & A2
Class II Biosafety Cabinet Type A1 & A2 are designed for the security and protection of operator’s product and environment from pathogenic agents and microorganisms transmitted in respiratory way and also for creation of a bacterial dust free air environment. It has a common plenum from which 30% of air is exhausted, and 70% re-circulated to the work area as part of the downflow. Type A cabinets drain out air directly back to the laboratory, and they may contain positive pressure contaminated plenums. When toxic chemicals must be employed as an adjunct to microbiological processes, these cabinets should not be used. Exhaust HEPA filtration only.
Removes airborne aerosols including biohazards, and not chemical fumes.
The Class II Type A1 consists of the positively-pressurized contaminated plenum bordering the ambient environment, and therefore is less safer than the Class II Type A2 that has a negative pressure surrounding the positively pressurized contaminated plenum. In any unlikely event of a leakage on the positive plenum, the leaking aerosol will be pulled by the negative pressure back to the positive plenum, which prevents it from leaking out. On the grounds of safety, the Type A1 design is now considered obsolete. In the A2 cabinet, approximately 70% of air from the positive plenum is re-circulated as down flow
Biosafety Cabinet Class II - B1
The Class II Type B1 biological safety cabinet has a common plenum from which 70% of air is exhausted, and 30% re-circulated to the work area as the down flow.
Type B1 cabinets also have a dedicated exhaust feature that eliminates re-circulation when work is performed towards the back within the interior of the cabinet. Toxic chemicals employed as an adjunct to microbiological processes should only be employed if they do not interfere with work when re-circulated in the downflow.
Biosafety Cabinet Class II - B2
In the case of Class II Type B2 cabinet all inflow and downflow air is exhausted after HEPA filtration to the external environment without recirculation within the cabinet. This means that Type B2 cabinets are apt for working with toxic chemicals employed as an adjunct to microbiological processes under all conditions since no re-circulation occurs. In theory, Type B2 cabinets may be measured to be the safest of all Class II biological safety cabinets since the total exhaust feature acts as a fail-safe in the event that the downflow and / or exhaust HEPA filtration systems cease to function normally. However, Class II Type B2 cabinets, in practice, are difficult to install, balance and maintain.
Biosafety Cabinet Class III
The Class III biological safety cabinet provides an absolute level of safety, which cannot be attained with Class I and Class II cabinets. All Class III cabinets are usually of welded metal construction and are designed to be gas tight. Work is performed through glove ports in the front of the cabinet. During routine operation, negative pressure relative to the ambient environment is maintained within the cabinet. This provides an additional fail-safe mechanism in case physical containment is compromised. On all Class III cabinets, a supply of HEPA filtered air provides product protection and prevents cross contamination of samples. Generally the exhaust air is HEPA filtered and incinerated. Alternatively, double HEPA filtration with two filters in series may be utilized.
Materials are transferred into the cabinet using a pass-through unit installed at the side of the work area. Class III cabinets usually exhaust air back to the laboratory; however, air may also be exhausted via a dedicated ductwork system to the external environment. When a dedicated ductwork system is employed, they are also suitable for work employing toxic chemicals as an adjunct to microbiological processes. All Class III biological safety cabinets are suitable for work with microbiological agents assigned to biosafety levels 1, 2, 3 and 4. They are frequently specified for work involving the most lethal biological hazards.

Fume hoods typically protect only the user, and are most commonly used in laboratories where hazardous or noxious chemicals are released during testing, research, development or teaching. They are also used in industrial applications or other activities where hazardous or noxious vapors, gases or dusts are generated or released.
Air Shower
Clean rooms provide controlled environments for the production of contaminant-free products. Air showers play a vital role in maintaining these clean-critical settings by removing loose particles of contamination from people and products before they enter the clean room.
Self-cleaning air showers help reduce product defects and increase production yields. These devices can also improve the performance of and reduce maintenance needs for the clean room itself by lowering the overall contamination load. Without an air shower’s “pre-cleaning” process, a cleanroom’s air filtration system would have to absorb all contaminants, which would increase energy consumption and maintenance costs.
Our Products designs and manufactures cleanroom air showers in a range of standard air shower sizes and configurations. We have self-cleaning air showers to meet most customer requirements; however, if your cleanroom requires a special or unique entry system, we also provide custom air showers that are built to match your unique specifications.

Filters
HEPA Filter
HEPA is an acronym for "High Efficiency Particulate Air" or "High Efficiency Particulate Arrestance." This acronym refers to a filter that is manufactured, tested, certified, and labeled in accordance with current HEPA filter standards. There are several sub-classes within the HEPA classification. The minimum HEPA category requires the filter to capture 99.97% of the 0.3-micron (0.000012-inch) particles in the air passing through the filter
HEPA is an acronym that stands for High Efficiency Particulate Air, so a HEPA filter is a High Efficiency Particulate Air filter. Filters, whether for an air purifier or other implementation, come with many benefits and claims.
What sets HEPA filters apart from the rest is their claims are more than just claims. Because in order to be called a true HEPA filter it has to be first be tested and approved, you know exactly what to expect. The Institute of Environmental Sciences and Technology dictates that a HEPA filter must trap 99.97% of particulates 0.3 microns or larger. This does not mean that the filter cannot trap particles smaller than 0.3 microns, because many HEPA filters can; it is simply the threshold that must be reached in order to carry the HEPA name.
Cleanroom Fan Filter Units
Cleanroom fan filter units are self-contained devices that utilize HEPA filters. We offer a full line of standard and custom fan filter units, with numerous options available to meet your specific cleanroom requirements.
Motor Blower
A blower motor is the component within a home’s HVAC system. At the heart of most automotive HVAC systems is a component called a blower motor. This descriptive term refers to the fact that these components are electric motors that are attached to fans and used to move air through the HVAC system. In most cases, a single blower motor is responsible for delivering both hot and cool air, on demand, depending on how the climate controls are set.
UV Lamps
The UV light uses a short wavelength that can destroy harmful microorganisms within the hood. This process removes the microorganism’s reproductive capabilities and kills the germs within the hood.
