Air Shower Selection Guide: 3 Key Points
A successful air shower selection process extends far beyond simple equipment procurement, requiring comprehensive analysis of the cleanroom’s operational needs with a core emphasis on balancing personnel passage efficiency and cleanliness requirements.
As a trusted supplier of air purification equipment, Baihong Purification recognizes that air showers serve as a critical barrier for maintaining clean zone environmental quality. A well-designed selection strategy not only ensures optimal cleanliness but also enhances operational efficiency and business outcomes. Drawing on our professional expertise , this article will guide you through the key considerations for air shower selection.
1. Air Shower Selection Basics: Assessing Passage Requirements
(1) Low-frequency passage scenarios: If the cleanroom has a small number of personnel and low entry/exit frequency, 1-2 standard-sized air showers can meet daily requirements.
(2) High-frequency concentrated passage scenarios: If there is a large number of personnel with concentrated entry and exit, such as during production shift changes, it is essential to calculate the number of air showers or increase the passage length based on the peak traffic volume. This fundamentally avoids queue congestion and ensures every employee completes an effective air shower purification process.
(3) The width and height of air showers are typically fixed values to ensure optimal airflow coverage and passage comfort. Their length can be flexibly adjusted according to actual traffic volume. A larger number of personnel may justify increasing the length to accommodate more people per shower cycle, significantly improving efficiency.
2. Key Consideration for Air Shower Selection: The Indispensable Interlocking Function
The interlocking function is a critical design feature of air showers. It ensures that the front door (non-clean side) and rear door (clean side) cannot be opened simultaneously, thereby preventing non-clean air and contaminants from directly entering the clean area.
(1) Automatic Air Shower: After entering, personnel must complete the shower process with one door firmly closed before the other door unlocks. This prevents uncleaned personnel from directly entering the clean area, further reducing contamination risks.
（2）Emergency Indication: Baihong air showers are equipped with user-friendly emergency indicator buttons and human-shaped indicator lights showing “Enter/Wait” status on both sides of the door. During daily operation, these indicators provide clear passage guidance. In emergency situations, pressing the emergency button allows both doors to open simultaneously, effectively balancing stringent cleanliness control requirements with personnel safety needs.
3. Baihong Air Shower: Modular Design with Flexibility
Addressing the pain points of traditional integrated air showers—such as difficult transportation, complex installation, and poor adaptability—Baihong Purification’s air showers adopt a modular assembled structural design.
（1）Transportation and Installation: The equipment can be disassembled into standardized components, allowing passage through narrow corridors and avoiding transportation blockage risks. The air shower is fixed and assembled with precision screws, eliminating the need for large lifting equipment. This reduces the construction period by over 30% and minimizes interference with existing floors and walls of the cleanroom.
(2) Flexibility and Sustainability: The system supports future adjustments by allowing flexible addition or reduction of modules to modify the air shower’s length or functionality based on changes in personnel scale or usage scenarios. This eliminates the need for complete equipment replacement, significantly reduces later renovation costs for enterprises, extends the practical service life of the equipment, and truly achieves “one-time investment, long-term adaptability.”
