Seven Types of Purification Equipment Commonly Used in Clean Rooms

In modern, high-standard Clean Room Environments, air cleanliness and contamination control are crucial for ensuring product quality and process safety. Purification equipment such as air showers, cargo showers, transfer windows, high-efficiency air vents, and clean benches, as core components of dust-free workshops and cleanrooms, not only effectively removes dust particles from the air and surfaces but also prevents contamination from entering critical areas, thereby ensuring a safe and stable production environment. This article will detail the characteristics, functions, and application scenarios of various types of purification equipment, helping companies to rationally select and configure cleanroom equipment and improve the overall cleanliness of their production environments.

Air Shower Series Product Introduction

Air Shower

The air shower series is a highly versatile, localized purification device installed between cleanrooms and non-cleanrooms. When people and goods enter the clean area, they are aired through the air shower. The clean air removed dust carried by them, effectively blocking or reducing the amount of dust entering the clean area. The front and rear doors of the air shower/cargo shower are electronically interlocked, acting as airlocks to prevent unpurified air from entering the clean area.

Cargo Shower Room

A cargo shower room, as the name suggests, is a dedicated air shower room for cargo, also known as a cargo shower channel or cargo shower door. It is widely used in logistics corridors for electronics, food, and packaging companies, showering goods, raw materials, and tools entering cleanrooms for processing to remove dust particles.

Cargo shower rooms are customizable depending on the size of the company's logistics corridor and the method of cargo transportation. Key features include:

• Standard Cargo Shower Room

• Infrared Voice-Prompted Cargo Shower Room

• Automatic Sliding Door Cargo Shower Room

Pass Box

Pass Through Box is primarily used for transferring small cargo between clean and non-clean areas, or between cleanrooms. It effectively reduces the number of cleanroom door openings, minimizing contamination in the cleanroom.

• The cabinet can be sprayed with plastic and lined with stainless steel for a durable and aesthetically pleasing design.

• The two doors feature electronic or mechanical interlocking to prevent dust from entering the cleanroom from the lower cleanroom level.

• Essential equipment for cleanrooms.

HEPA Box

HEPA Box is the terminal air supply devices for cleanroom air conditioning systems in new or renovated Class 10,000 and Class 100,000 turbulent flow cleanrooms. They are widely used in the electronics, precision machinery, metallurgy, chemical, medical, pharmaceutical, and food industries.

• Main components: plenum chamber, high-efficiency filter, aluminum alloy diffuser, and standard flange interface.

• Bottom-mount design facilitates filter installation and replacement.

• The high-efficiency filter utilizes mechanical compression or liquid tank sealing to ensure leak-free and reliable sealing.

Clean bench

The clean bench in a cleanroom maintains high cleanliness within the work area, creating a dust-free and sterile environment.

Main Components

• Pre-filter, HEPA filter

• Fan unit

• Casing and static pressure box

• Tabletop and associated electrical components

Construction requirements

• Tabletop: Wood with plastic veneer or stainless steel

• Case: Hot-rolled thin steel plate or cold-rolled thin plate with overlapped edges. Sound-absorbing material should be applied to the interior surface.

• Case sealing: Sealant should be used to seal gaps.

• Operating area cross-section: Optimally match the air filter cross-section to minimize blind spots.

• Fan and motor: High-pressure, low-noise, compact fan with vibration reduction measures.

• Lampshade: Fluorescent lamps should be installed inside the shade as much as possible, allowing clean airflow.

• Pre-filter: Large capacity, initial resistance less than 50 Pa.

• HEPA filter: Large-area design with a double-ring sealing system.
