Before purchasing an air shower, it is essential to fully understand the following requirements to ensure the selection of suitable equipment:

1. Cleanliness Requirements

• Cleanliness Class: Determine the required cleanliness class based on the usage environment (e.g., ISO 14644 standards).

• Filtration Efficiency: Check the efficiency of the HEPA or ULPA filters in the air shower to ensure they meet cleanliness requirements.

•  

2. Size and Capacity

• External Dimensions: Ensure the air shower dimensions fit the installation site.

• Internal Space: Choose an appropriate capacity based on the number of users and frequency of use to avoid overcrowding.

•  

3. Air Velocity and Noise Level

• Air Velocity: Typically required to be between 20-25 m/s to ensure effective dust removal.

• Noise Level: Select an air shower with lower noise levels to avoid impacting the working environment.

•  

4. Material and Durability

• Material: Choose materials such as stainless steel or coated steel plates that are corrosion-resistant and easy to clean.

• Durability: Ensure the equipment has a robust structure for long-term stable operation.

•  

5. Control System

• Operation Mode: Choose between manual, automatic, or intelligent control systems based on needs.

• Features: Ensure the system includes functions such as timing, air velocity adjustment, and fault alarms to enhance user experience.

•  

6. Installation and Maintenance

• Installation Requirements: Understand installation conditions, such as power supply, air source, and space requirements.

• Maintenance Convenience: Select equipment that is easy to maintain to ensure long-term stable operation.

•  

7. Compliance and Certification

• Industry Standards: Ensure the equipment complies with relevant industry standards, such as GMP and ISO.

• Certification: Check for certifications like CE and UL to ensure safety and reliability.

•  

8. Supplier and After-Sales Service

• Supplier Reputation: Choose a supplier with a good reputation and extensive experience.

• After-Sales Service: Understand the warranty period, repair response time, and technical support availability.

•  

9. Cost and Budget

• Initial Cost: Consider the equipment price as well as transportation and installation costs.

• Operating Cost: Evaluate long-term costs such as energy consumption, maintenance, and filter replacement.

•  

10. User Feedback and Case Studies

• User Reviews: Refer to feedback from other users to understand the actual performance of the equipment.

• Success Cases: Review the supplier's success cases to ensure the equipment's reliability in similar environments.

Conclusion

Before purchasing an air shower, it is necessary to comprehensively consider factors such as cleanliness requirements, size, air velocity, material, control system, installation and maintenance, compliance and certification, supplier services, and cost budget to ensure the selection of the most suitable equipment.
