Postbox for clean space

Postbox for clean space
Post boxes are one of the vital equipments in the clean room industry, which are designed to control and reduce contamination during the transfer of tools and equipment into these spaces. These equipments are made with the aim of maintaining health standards and preventing pollutants from entering the clean environment.​

Use of mailboxes in clean rooms
In manufacturing processes that require ultra-clean environments, such as the pharmaceutical, electronics, biotechnology, and semiconductor industries, contamination control is important at all stages. Therefore, the use of a post box to transfer equipment and materials into the clean room plays an important role in preventing polluting particles from entering the environment.

One of the key features of post boxes is to be equipped with an interlock system.This system prevents the opening of both doors at the same time, thus preventing contamination from entering the clean room. This system can be manual or electric, and its selection is based on the needs of the clean environment.
 

Key Points in Choosing a Pass Box
 

Choosing the right pass box depends on various factors that influence its final price. Some of these factors include:

• Build Quality: Using durable and rust-resistant materials such as stainless steel, known for its corrosion resistance and ease of cleaning, is essential in pass box construction.

• Interlock System: The type of interlock system, whether manual or electric, is a crucial feature to consider. Electric interlock systems usually offer higher precision and operate automatically, while manual interlocks are more suitable for lower-cost environments.

• Size and Dimensions: The size of the pass box varies depending on the volume of equipment being transferred into the cleanroom. Larger sizes generally come with a higher price.

• Filtration Level: Some pass boxes are equipped with HEPA filters that can capture finer particles, ensuring that the air inside the pass box remains clean during the transfer of equipment.
   

Advantages of Using a Pass Box in a Cleanroom

• Prevention of Cross-Contamination: A pass box allows for the transfer of items into a cleanroom without introducing external contamination into the controlled environment.

• Increased Efficiency: Pass boxes reduce the need for frequent production stoppages and maintenance of cleanrooms, thereby increasing overall productivity.

• Employee Safety: By preventing harmful substances from entering the cleanroom, pass boxes help ensure the safety of the staff working inside.

Pass Box Pricing

The price of pass boxes depends on several factors, including:

• Material Quality: High-quality materials such as stainless steel tend to be more expensive but also enhance the durability and lifespan of the device.

• Type of Interlock System: Electric interlock systems generally cost more than manual ones, as they offer greater convenience through automation.

• Size and Dimensions: Larger pass boxes designed for transferring bulky equipment are typically more expensive than smaller models.
