Dynamic pass box is designed to allow material transfer through controlled environment without much personnel movement. They are self-contained units installed at the entrance to clean rooms. They minimize the amount of particulate contamination and is easy to install and adaptable to existing facilities. This box helps in prevention of contaminants entrance in the clean room. This is designed mainly to minimize traffic and cross contamination between two areas

Air Showers for Cleanrooms
​

Air Showers have become an integral component of the modern cleanroom because their benefits more than pay for the

small amount of space they occupy. With their interlocking doors and automatic cycling,

air showers act as traffic guards, controlling passage into and out of the cleanroom.

Downflow Booth for Pharmaceutical Manufacturing. when you need to provide a clean, contained environment for the safe handling of pharmaceutical powders in dispensing, weighing, sampling, or subdivision operations, the PharmAir booths are a highly effective option.
By our fully trained engineers to ensure the system fully conforms to your requirements. To complete the package, our dedicated Aftersales department will supply total support.

ISO 14644 classification for cleanrooms is based on the formula

Cn = 10N (0.1 / D) 2.08

Where

Cn = maximum permitted number of particles per cubic meter equal to or greater than the specified particle size, rounded to whole number

N = is the ISO class number, which must be a multiple of 0.1 and be 9 or less

D = is the particle size in micrometers

Four basic components define a controlled environment:
1) Cleanroom Architecture – Materials of construction and finishes are important in establishing cleanliness levels and are important in minimizing the internal generation of contaminants from the surfaces.



2) The HVAC System – The integrity of the cleanroom environment is created by the pressure differential compared with adjacent areas through heating, ventilation and air-conditioning system.



The HVAC system requirements

Why should the buffer room be set up in the purification project?



The buffer room is set on the one hand to prevent contaminants from entering the clean room and on the other hand to compensate for the pressure difference.

Buffer room is best to keep negative pressure on the clean room and positive pressure on the outside.

Cleaning rooms with more stringent requirements are often equipped with two or more buffer rooms.

What are the design principles and forms of air distribution in industrial ventilation projects?



When we do ventilation design for an industrial plant, ventilation engineering design is involved in clean production workshop, general workshop, logistics warehouse, and activity area of staff office.

The ventilation effect of indoor environment is closely related to the air distribution in the region. So there are many kinds of air distribution, how do we choose our scheme?

3 Reasons for Maintaining Positive Pressure Value of Clean Booth
Clean booth is a kind of simply constructed clean room. Clean booth with a variety of clean grades and space collocation can be designed and manufactured according to the use requirements.
Therefore, its main characteristics are simple, flexible and easy to install, short construction period and mobility.

Introduction of Clean Work Bench

Clean work bench is designed to meet the needs of cleanliness of local working areas in modern industry, optoelectronic industry, biopharmaceuticals and scientific research and experiment.

Its working principle is that the air is sucked into the pre-filter through the fan and filtered into the high-efficiency filter through the static pressure box.
The filtered air is sent out in the state of vertical or horizontal air flow, so that the operating area can

Dispensing Booth Introduction
With the continuous development of science and technology, experimental instruments are constantly being updated, and the requirements of experimental instruments in related industries are gradually increasing.
In order to meet the needs of the vast number of laboratory decoration instruments, in 2015,GuangZhou HaoAir Purification Technology Co., Ltd. launched New product - negative pressure dispensing booth.

The weighing chamber is a local purification device

CLEANROOM AIR SHOWERS: EVERYTHING YOU NEED TO KNOW

An air shower is designed to function as a sort of gateway controller between your cleanroom and the rest of the world.
When used properly, an air shower can cut down on a vast majority of potential contaminants and helps ensure that your product remains safe and uncontaminated.
Today, air showers have become relatively commonplace because of their benefits, and comparatively small price. So what’s the deal with cleanroom air showers, and

The Airflow Control of Cleanrooms
Many professionals around the globe make the best use of cleanrooms in order to standardize their production and research processes. At a glance, the outer appearance of cleanrooms may look normal and similar to the conventional rooms that have glass walls, doors, and windows. However, in the context of functionality, cleanrooms are quite different from the other rooms. The most significant characteristic associated with cleanrooms is the strict airflow control
