How much do you know about laminar flow hoods?

The concept of a laminar airflow device:

A laminar air flow unit is also called a laminar flow hood, laminar flow cabinet, or compounding hood.

A laminar flow hood is an air purification equipment that provides Class A unidirectional flow and creates a local high cleanliness environment.

The role of laminar airflow device:

A laminar flow hood is one of the equipments that can shield and isolate operators from products. Its main purpose is to avoid product contamination.

It is ideal equipment for achieving high purification level requirements in low purification areas.

It is mainly used to protect the production process of sterile drugs.

The structure of the laminar flow hood:

It is mainly composed of the tank, fan, high-efficiency air filter, homogeneous membrane, lighting fixture, etc.

How a laminar flow hood works:

After passing through HEPA at a specific air velocity, the air is equalized by the homogeneous membrane, so the clean air flow is sent to the working area in a unidirectional flow.

It is generally installed above the working area, and the air in the active area is replaced by clean air in a vertical unidirectional flow.

Local micro-positive pressure is formed in the working area, which can effectively prevent the airflow in the background area from penetrating.

Features and characteristics of laminar flow hood:

It can be used alone or in combination.

Double layer negative pressure structure, no leakage risk.

HEPA ensures low resistance and high efficiency, and the liquid tank seal is more reliable.

The inside and outside are consistent, clean, and free of dead ends.

Various forms of control to meet different requirements of customers.

Multiple pressure equalizing, uniform air velocity, and good unidirectional flow pattern.

Imported fan, large residual pressure, low noise, energy saving, reliable performance.

The design is simple, the maintenance cost is low, and an efficient Class A clean environment is provided.

It can be used in the assembly, testing, inspection, and other production processes of sterile products requiring ultra clean.

Integrated fan filter module, low noise.

Application of laminar flow hood:

It is widely used in electronics, pharmaceuticals, chemicals, science and technology, bioengineering, and other industries.

It is widely used in the safe washing, drying, filling, and sealing lines of precision electronic device operation rooms and pharmaceutical workshops, antibiotic bottle washing, drying, filling and sealing lines, oral liquid bottle washing, drying, filling and sealing lines, and clean air supply treatment on large infusion production lines.

Notes for laminar flow hoods:

It should be installed under Class D or higher working conditions.

The background area shall be cleaned 5 minutes in advance to make the cleanliness meet the process requirements.

It is forbidden to place unnecessary articles in the working area and try to avoid actions that obviously disturb the airflow.
