Cleanroom diffuser

Cleanroom diffusers, also known as air distribution plates or rectifiers, are core functional components at the end of cleanroom air supply systems (high-efficiency air outlets, laminar flow ceilings), playing a crucial role in regulating airflow distribution and ensuring cleanliness.

Material types: Cold-rolled steel sheet with powder coating; Perforated aluminum sheet with powder coating; Honeycomb aluminum sheet; Stainless steel

Function:
**Airflow control:
The diffuser can effectively adjust the direction and speed of airflow, avoid airflow concentration in a specific area, and achieve uniform air supply.
**Reduce noise:
The design of the diffuser can reduce the friction resistance of air passing through the air outlet and reduce noise.
**Improve filtration efficiency:
The diffuser can ensure the normal operation of the air filter in the clean room and improve the filtration efficiency.
** Compact structure:
The design of the diffuser is usually closely integrated with the structure of the high-efficiency air outlet, and the overall structure is compact, which is easy to install and maintain.
** Strong customizability:
The diffuser can be customized according to different application scenarios and needs to meet the special needs of various clean rooms.

Design &Maintenance Features:

Modern diffusers are mostly designed with a detachable structure. Some high-end models also incorporate magnetic closures, handles, and limit slots for easy and quick filter replacement and maintenance. Maintenance Precautions: Diffuser holes are prone to dust accumulation and clogging, requiring regular cleaning. It is recommended to gently wipe with a non-woven cloth dampened with alcohol, avoiding the use of a hard brush to prevent damage to the panel surface; During installation, the diffuser must be tightly fitted to the HEPA filter's outlet surface, with a gap controlled within 50mm to prevent turbulence that could affect the airflow rectification effect.

Use scenario:
** Clean room:
The high-efficiency air outlet is the terminal filtration device of the clean room. The diffuser can effectively control the air supply and ensure the air quality inside the clean room.
**Operating room:
In places such as operating rooms where air cleanliness needs to be strictly controlled, the diffuser can ensure the cleanliness of the surgical environment and reduce the risk of infection.
** Electronics factories, pharmaceutical factories, etc.
In these production sites with special requirements for the environment, diffusers can ensure the cleanliness of the production environment and avoid product contamination.
**Laboratory:
Some equipment in the laboratory requires strict air filtration and air supply control, and diffusers can ensure the normal operation of the equipment.
** Other purification sites:
Diffusers can play their role in any place where air purification and control are required.

**Advantages:
(1)Uniform air supply: It can ensure uniform distribution of air flow in the air supply area and avoid air flow concentration in a specific area.
(2)Reduced energy consumption: The diffuser can reduce the friction resistance of air passing through the air supply port and reduce energy consumption.
(3)Improve comfort: The diffuser can control the air flow velocity and temperature in the air supply area and improve comfort.
(4)Reduced maintenance costs: The diffuser is simple in design and easy to maintain and maintain.

**Standard Performance Parameters & Customization Instructions**

(1) Size Parameters
Finished product dimensions: 440×440mm, compatible with industry standard sizes of high-efficiency air outlets and cleanroom ceiling joists, can be directly matched and installed.
Compatible filter size: 320×320mm, the mainstream configuration for small and medium-sized high-efficiency air outlets in purification engineering.

(2) Performance Parameters
**Work scenario compatibility: Compatible with Class 1000 to Class 100,000 cleanroom purification air supply systems, can stably ensure the cleanliness of the air outlet when used with a high-efficiency filter.

**Air outlet uniformity:Through the design of long strip openings and central perforation, the concentrated air outlet can be evenly diffused, and the air outlet non-uniformity deviation is ≤10. %, ensuring stable airflow distribution in the space

**Weather resistance: After surface powder coating, it can be used for a long time in clean indoor environments with temperatures of 5~40℃ and relative humidity ≤80%, and is not prone to rusting, aging, or deformation

II. Customization Instructions
This diffuser plate supports flexible customization, and parameters can be adjusted according to the usage scenario:

(1) Material customization
Cold-rolled steel plate powder coating (standard model, cost-effective, meeting most common cleanroom scenarios), aluminum plate powder coating (lighter weight, suitable for scenarios with limited ceiling load-bearing capacity), and stainless steel (mostly 304 stainless steel, meeting special scenarios with anti-corrosion and hygiene requirements such as pharmaceuticals and food) are available.

(2) Size customization
In addition to the standard 440×440mm, different specifications can be customized according to different filter sizes: such as a 600×600mm diffuser plate to fit a 480×480mm filter, a 720×720mm diffuser plate to fit a 600×600mm filter, and the opening layout and overall thickness can also be adjusted according to special installation requirements. (3) Customization for specific scenarios If it is a special clean environment such as an operating room or a laminar flow ceiling, the material and opening density can be adjusted accordingly to adjust the diffusion effect in accordance with different levels of cleanliness requirements. At the same time, it supports the selection of dust-free antibacterial spray coating to meet high hygiene requirements.
