Kỹ Thuật
A Dynamic Pass Box is a device installed between two rooms with different cleanliness levels to remove contaminants and dust from tools and materials before they are brought into the cleanroom. Dynamic Pass Boxes are commonly used in the electronics, chemical, medical, and pharmaceutical industries.
When an item is placed in the Dynamic Pass Box, the system is activated by a sensor. Clean air, filtered through a HEPA filter, is blown out through perforated panels on the ceiling, removing 99.99% of dust particles as small as 0.3 microns. The air velocity ranges from 0.36 to 0.54 m/s or can be adjusted according to customer requirements. Contaminated air is sucked in through vents on the sides of the box, filtered, and then recirculated.
Stainless Steel: Customers can choose from stainless steel 304, 201, 430, or 316 based on actual needs.
Electrostatic Powder Coated Steel: The electrostatic powder coating has a protective layer that prevents corrosion and oxidation.
Hepa stands for High Efficiency Particulate Air Filter, which meets HEPA standards for air filtration efficiency.
The HEPA filter is made of ultra-fine glass fibers that can block many tiny particles in the air. The air passes through the dense filter, trapping pollutants through differential pressure. After passing through the filter, dust particles are retained at the filter's entrance. This process is repeated continuously, preventing dust particles from escaping back into the air. Fine dust particles as small as 0.3 microns (µm) are retained by the filter.
In typical Dynamic Pass Boxes, HEPA H13 filters are used.
Pre-filters are used to capture coarse dust particles larger than 5 microns, typically made from synthetic fiber material. Depending on thickness, they are classified as G2 (10mm), G3 (15mm), and G4 (20mm).
Centrifugal Fan: The required air velocity for Dynamic Pass Boxes ranges from 0.36 to 0.54 m/s. Therefore, fans are chosen for their compact size, low noise, high air pressure, and low energy consumption.
Perforated Panel: Designed as a perforated mask, it helps distribute air evenly over the entire product.
Manual Mode: The device operates based on programmed signals and parameters set by personnel, allowing for adjustments in air shower duration, lighting control, UV light control, and emergency stop button.
Automatic Mode: The device operates based on preset signals and parameters without personnel intervention. The system adjusts its operation automatically based on factors like sensors, time, or other input signals.
Emergency Stop Button: Used in Dynamic Pass Boxes for the following purposes:
Prevent Accidents: The emergency stop button allows operators or personnel to quickly halt machine operations in case of an emergency.
Protect Equipment: During unexpected incidents, using the emergency stop button can protect machinery from significant damage due to abnormal operation.
Enhance Workplace Safety: The emergency stop button is essential in safety procedures, ensuring that workers can intervene quickly to reduce risks.
Simplify Operation: Designed for easy use even in emergencies, the button ensures that users do not need to remember complex procedures.
Improve Psychological Safety: The presence of an emergency stop button provides workers with a sense of security, knowing they have a means of immediate intervention when needed.
Legal Compliance: Many labor safety regulations and standards require the installation of emergency stop buttons on machinery and equipment, helping businesses comply with these regulations.
Pharmaceutical Industry: Medicines require high quality and absolute sterility. A standard Dynamic Pass Box helps keep medicines in optimal condition.
Cosmetics Manufacturing: Similar to the pharmaceutical industry, cosmetics also require standard air shower chambers to prevent chemical components from being contaminated with bacteria and dust.
Electronics Manufacturing: Electronics manufacturing demands absolute dust cleanliness, making Dynamic Pass Box essential for producing high-quality electronic products.
Food Processing: Meeting food safety standards in processing and product quality is crucial for any establishment. Dynamic Pass Box systems are among the best solutions in this field.
Medical Equipment Manufacturing and Treatment: Dynamic Pass Boxes are also widely used in medical fields, limiting and isolating harmful pathogens in public spaces and protecting medical equipment.
