What is the Working Standard of a Vertical Laminar Flow?

To understand the working of a Vertical Laminar Flow pay attention to the given points:

• From the upper part of the unit, the air is pulled
• A motorized fan that works with the HEPA or ULPA filter traps the air.
• These filters then remove dust and decontaminated particles from this air, supplying clean air
• The purpose of the back plenum is to allow recirculation of air for increasing the lifespan of the filter, this is due to the reduction in the dirty air passing from this filter.

How to Differentiate Between a Horizontal Laminar Flow and a Vertical Laminar Flow?

In a horizontal laminar flow cabinet, HEPA or ULPA filtered air is directed from behind the equipment towards the operator of the cabinet.

On the other hand, in the Vertical Laminar Flow, the air proceeds from the upper level of the unit with the help of filters and goes down to the workspace.

The fans and filters are installed on the top part of the cabinet in the Vertical Laminar Flow. The particles not trapped in these filters are pushed out from the front section of the cabinet.

It directs the filtered air over the workspace or the laboratory flooring after completely removing the impurities or contaminants in it. The unit can be placed on a conventional lab bench since the fans and the filter are located on the upper part of the assembly.

Because of fan and filter location, a flooring area and a worktop will be essentially required in the vertical models. In the pharmaceutical industry, a Vertical Laminar Flow is needed to deal with ultra-small particles and for the maximum protection of the operator, a front sash is used.

A horizontal laminar flow cabinet will require a deeper workstation and the hands and gloves of the operators must be less contaminated.

Horizontal Laminar Flow

Why is Vertical Laminar Flow Better than Horizontal Laminar Flow?

There are multiple reasons for preferring the Vertical Laminar Flow over the horizontal one, some of which include:

• Needs less flooring area.
• Can be fixed on a conventional bench.
• A top filter grant for feasible access.
• Lessen the cross-infection of products placed on the workspace.
• It is frequently selected due to its resemblance, on the mini scale as the layout of a clean room, in which filter/fan units are located in the ceiling typically.

By managing the laminar flow downside, it will strengthen the outcome of the gravity and wipe particles out of the enclosure, from the front access area generally.

Micro-infections may not have considerable weightage, but most particles do sort out on the workspace at the end of the flooring of a room, and this vertical flow assists get them there quicker.

When to Choose a Vertical Laminar Flow Over the Horizontal Laminar Flow?

A Vertical Laminar Flow is far better as compared to a horizontal one, the reasons are:

• The Vertical Laminar Flow does not process as much turbulence while striking large products inside the flow, as compared to the turbulence in a horizontal flow.
• If the requirement of your procedure needs that soldering fumes or blended powders be used, don’t use this equipment. Soldering condensation can be hazardous because of the metal oxides and acidic vapors from flux.
• Only use it to deal with the non-toxic powders or items which are generated on the workspace.
• Generally, as the filters are located on the upper side of the Vertical Laminar Flow, the height of the working surface should be tall enough to accommodate all these structures.

What are the Accessories Used with the Vertical Laminar Flow?

A number of accessories that can increase the productivity of your Vertical Laminar Flow are:

• It comes with a UV germicidal lamp for interior decontamination of the contents before using this equipment, to avoid contamination.
• The ionizing bar manages electrostatic changes in flow hoods and makes the benches clean and supply an uninterrupted stream of static and neutralizing ions for the protection of sensitive stuff against decontaminants.
• The air velocity sensor is used to measure the velocity of the air flowing inside this system.
• Many other alarms and sensors are present to detect and monitor several parameters including pressure and others.

What is the Difference Between a Vertical Laminar Flow and a Biohazard Safety Cabinet?

Vertical Laminar Flow

It facilitates an area free from impurities to maintain a controlled environment for lab specimens, products, and other samplings.

It passes the HEPA-filtered air in a direction downwards to the working space. One of the most considerable points you must keep in mind is that the Vertical Laminar Flow is fit for non-toxic stuff that is safe for an operator to inhale.

This is why it offers limited protection for workers. However, it establishes enough protection for the product. It is not suitable to protect the user and also it is not strong enough to protect the surrounding atmosphere from getting contaminated.

These types of hoods never permit the contaminated air to enter from the exterior of the cabinet and the airflow discharges into the room from inside of it. So, if your process requires dealing with toxic or hazardous substances, it is not suitable.

Biohazard Safety Cabinet

Biohazard safety cabinets are clean room and laboratory products that come with HEPA filters for the protection of users, products, and the surroundings from toxic materials.

These are manufactured to decontaminate the toxic air before you release it into the environment. Consequently, all disease-causing agents, viruses, and bacteria are retained in this biohazard safety cabinet.

Frequently, to conduct research these cabinets are used in laboratories, medical tests, and multiple kinds of observations, that should be performed in a sterile room. The class of biohazard safety cabinet depends upon the type of protection you want to achieve for your procedure:

• Class 1 biological safety cabinet is used for operator protection only
• Safety cabinet class 2 is used to protect the operator, product, and surroundings from toxic or contaminated products that can cause diseases and hazards for humans
• Biological safety cabinet class 3 is used to protect the operator, environment, and materials when dealing with severely potent pathogens.

Biohazard Safety Cabinet

How is a Vertical Laminar Flow Different from a Fume Hood?

Chemical Fume Hood

A chemical fume hood is a confined, ventilated workbench that comes up to prevent harmful materials by directing away from the air from the worker.

Filters are not required for usage and air is diluted because it passes through a vent system before it is out of the laboratory. One important thing about the chemical fume hood is its contamination protection for the user as well as the environment. But the drawback is that it doesn’t assure the protection of the samples.

You can use a fume hood for processes involving toxic chemicals, hazardous vapors, poisonous gases, harmful drugs, and also for flammable materials.

Vertical Laminar Flow

These are essentially designed for the protection of lab specimens and products from contaminants by directing air from High-Efficiency Particulate Air (HEPA) filters towards a sterile workstation.

A Vertical Laminar Flow Hood directs the HEPA-filtered air down to the workbench which then goes outside. This air escapes via the surface holes or holes present in the front section.

The downward airflow is better in terms of protecting the worker and the surrounding environment and it produces less turbulence. You can frequently use it for the preparation of media, in medicine preparation industries, assembling, and the manufacturing of electronic devices.

What Instructions are Necessary to Consider When Working in a Vertical Laminar Flow?

While working in a Vertical Laminar Flow, here are some important things that you must consider:

• In the existence of biohazards, either vertical or horizontal laminar flow cabinets are not suitable. This is because these systems are designed only for achieving against non-hazardous materials.
• No matter which Vertical Laminar Flow design you select, be confident to run it for 15 minutes at least before you start critical operation, allowing the particles to sweep out from the enclosure.
• The sweeping direction must be kept in mind, from clean to filthy, in case you have a clean cabinet. It is important to wipe all the surfaces in a smooth motion, starting from the face of the filter and then coming downwards.
• It is crucial to carry out dirty operations, like unboxing samples, from the filter as far as possible, so that the filter stays clean.
