What is the purpose of using LAF?

Achieving ultra-clean air in class A (GMP) -100 (FE 209) – ISO

Laminar flow or more commonly “UNIDIRECTIONAL flow” is a form of flow in which the fluid flows slowly and in parallel lines.

 

In contrast, there is turbulent flow:

How does LAF work?

1- The entry of filtered air flow from the air conditioner or the surrounding environment

2- Passing air through advanced HEPA H13 / 14 filters by independent fan motor or air conditioner

3- Return air from the bottom to the LAF chamber or air conditioner or environment (open air)

 

LAF components produced by Faraz Kavian Clean Room Company

1- Structure in the form of a pendant from above or a column from below

2- Walls are made of PVC or glass curtains (removed in hospital type)

3- Special fan motor and plenum chamber

4- Swedish Camphil HEPA filter or French filter H13 / 14

What are the benefits of an air conditioning system in clean rooms?

1- Pressure difference monitor to observe the filling of HEPA filter with warning alarm

2- Speedometer to observe the laminar flow velocity

3- Intelligent system to control air flow velocity with filter filling with inverter

4- SS304 stainless steel frame and body as well as wheels for moving

5- IQ / DQ certificates along with necessary tests

Laminar air flow device is a new generation of uniform pressure distribution devices in the environment. The main purpose of this device is to filter the incoming air from the air conditioner and create a protected space; Free of any contaminated particles around the patient.

 

This series of devices have the ability to control different levels of pollution and create uniform air throughout the room.

These devices can be used in operating rooms of hospitals and clean rooms (clean rooms) that create a uniform and pollution-free environment. With this device, if necessary, more optional features can be used. This device is produced in a modular way and therefore has the ability to be easily installed in the operating rooms.

HEPA filter

HEPA filter is made by irregular and completely random interlacing of fiberglass, straw or mat fibers and their compression.

Are formed. H and 14 H – Fillers of two types 13

The frame around the filters is made of water-repellent aluminum.

A protective layer is placed on the clean air side.

Ability to install and set up quickly and easy to repair are the features of these filters.

LAF device components

The pressure chamber is made of steel with a diameter of 1 mm in the bodies and top sheet. It is made of RAL or 9010 AISI coated steel.

Body material can be 304 stainless steel

The joints are riveted together and insulated with silicone.

Steel is composed of U-shaped and Z-shaped profiles.

It is resistant to dirt and impact and is easy to clean.

60 x 60 cm central space for operating room equipment and lighting. The central space is insulated with plastic tape.

The height of the body is equal to 450 mm.

Laminar Flow Hood is actually a laminar flow hood.

This hood is used to control the contamination against penetration into the test environment and to direct the contamination caused by the test materials out of the test environment so that the laboratory staff and people are not harmed.

For this reason, laminar hoods and their types are the most important and main laboratory equipment.

In this type of hoods, a filter called Hepa filter is used. The function of HEPA filter is that it sucks the air inside the hood, which has a high probability of contamination, through a sucker, and expels clean air in a linear and gentle way.

To learn more about HEPA filter and its function, you can read what is HEPA filter

The inner chamber of the laminar hood is made of stainless steel and the outer body of this device is made of steel sheet with electrostatic furnace paint.

The reason for using stainless steel in the construction of the inner chamber of the hood is that in order to control the environment from pollution, the inner chamber should be seamless and empty space so that it is not possible to create fungus and mass inside the chamber.

The dimensions of the hood also vary according to the needs of the laboratory and the type of hood and can be made in different dimensions.

Laminar hoods have a variety of air patterns and are classified accordingly and have different applications.

Accordingly, laminar hoods are divided into two main types:

Hood with horizontal air flow

Hood with vertical air flow

Hood with horizontal air flow

In this example, the air hood is horizontal and looks like this:

The polluted air in the room through the pre-filter and the blower fan creates a flow of air in the lower layer of the HEPA filter in the working part.

This air then goes to the user to protect the products or samples in the cabin against dust or biological contaminants such as bacteria or fungi.

Advantages of horizontal laminar hood

Possibility to use large items inside the compartment

The air transfer in it is such that the user does not have any problems while working.

In this example, the airflow hood is vertical and looks like this:

The HEPA filter draws room air and blows clean air into the user in a very gentle and linear manner.

The pre-filter built into the hood empties the inlet air of dust particles.

It then passes through the main filter, which is HEPA, and is thoroughly cleaned and sterilized and blown into the material and the user.

Advantages of vertical laminar hood

It is possible to use large and large items and items in it.

Air is not blown directly into the user of the device.

The main components of laminar hoods are as follows:

The body of the device has two parts, the base and the cabin

The main working chamber is made of stainless steel and has internal channels to create negative pressure

UV lamp for sterilization

Removable or fixed protective glass door

Alarm system and device control keyboards

Electric motor

HEPA filter

In Class 3 hoods, a sample transfer tank and protective gloves will also be added to these components.
