Q1: What is the working principle of an air shower? Is it really effective?
A: An air shower utilizes clean air filtered by HEPA filters, jetting high-speed airflow of ≥25m/s onto personnel or object surfaces through rotating nozzles. This powerful airflow effectively blows off dust particles attached to clothes, hair, or goods, which are then recycled and purified through primary and high-efficiency filters, preventing pollutants from being brought into the clean area.
Scientific experiments and practices have proven that correct use of air showers significantly reduces pollution loads from personnel/materials and is an indispensable effective barrier for maintaining clean environments.
Q2: How to choose the right air shower material?
A: Material selection mainly depends on the usage environment and budget:
Powder-Coated Cold-Rolled Steel (Full Cold-Rolled): Economical and practical, high strength, electrostatic powder-coated surface, durable and aesthetically pleasing. Suitable for most conventional environments like electronics and precision manufacturing.
External Cold-Rolled, Internal Stainless Steel: The internal blowing area uses SUS304 stainless steel for wear resistance and easy cleaning; the exterior uses powder-coated steel to reduce costs. A highly cost-effective mainstream choice.
Full Stainless Steel (SUS304/316): Excellent corrosion resistance, meets GMP hygiene standards, easy to clean and disinfect. Strongly recommended for high-cleanliness or humid, corrosive environments like food, pharmaceuticals, and biological products.
Q3: How to choose between single-person, double-person, and multi-person air showers?
A: This mainly depends on the number of personnel in the clean workshop and the instantaneous flow rate during shift changes.
Single-Person Air Shower: Suitable for small workshops or laboratories with fewer people (e.g., fewer than 10).
Double/Multi-Person Air Shower: Suitable for medium to large workshops with more people (e.g., more than 30).
Air Shower Tunnel: For large factories with hundreds of people, multi-section combined air shower tunnels are recommended for continuous passage, significantly improving throughput and avoiding congestion during peak hours.
Deshengxin can plan the most reasonable air shower size and configuration based on your specific headcount and layout.
Q4: What is the appropriate setting for air shower blowing time?
A: Blowing time is typically adjustable between 10-99 seconds.
Generally recommended setting is 15-30 seconds.
Too short a time results in incomplete blowing effectiveness.
Too long a time affects passage efficiency and may cause personnel impatience.
Deshengxin air showers are equipped with LED displays and voice prompts, factory-preset to economical and efficient modes, which users can easily adjust according to actual needs.
Q5: What intelligent functions does Deshengxin air shower have?
A: We are committed to improving user experience and management efficiency:
Automatic Sensor & Interlock: Automatic sensor blowing upon entry, double-door electronic interlock (both doors lock during blowing to prevent forced passage), ensuring mandatory blowing procedures.
Intelligent Voice Prompts: Full voice guidance on operation procedures for user-friendly service.
Emergency Stop Button: In emergencies, power can be cut off with one button, unlocking both doors to ensure personnel safety.
Optional Access Control System: Can integrate card swipe, fingerprint, face recognition, etc., for personnel authority management and attendance recording.
Q6: How often should air shower filters be replaced? How to determine?
A:Primary Filter: Located at the return air inlet, responsible for intercepting large dust particles. Recommended cleaning or replacement every 1-3 months.
HEPA Filter: Located in the top plenum chamber, it is the core purification component. Typically replaced every 1-2 years.
Basis for determination: When the air velocity of the air shower drops significantly (e.g., below 18m/s), or a dust particle counter detects substandard outlet cleanliness, it should be replaced promptly. Deshengxin provides professional testing and replacement services.
Q7: My workshop space is limited, can I customize the air shower?
A: Of course. As a source factory, non-standard customization is one of Deshengxin's core advantages.
We encounter various complex site conditions and can provide:
Size Customization: Tailor-made according to reserved space.
Structure Customization: Such as corner air showers (L-shaped channels), three-door air showers (one in two out or two in one out), etc., perfectly adapting to special layouts.
Function Customization: Such as integrating automatic sliding doors, high-speed roll-up doors (for cargo air showers), etc.
Q8: What is the difference between a cargo air shower and a personnel air shower?
A: The principle is the same, but the design focus differs:
Personnel Air Shower: Smaller size, usually has a stainless steel threshold on the bottom plate, nozzle arrangement focuses on blowing all parts of the human body.
Cargo Air Shower: Larger size, no bottom plate design (convenient for carts to enter and exit), doors usually adopt wider manual double doors, automatic sliding doors, or high-speed roll-up doors. Nozzle arrangement focuses more on covering cargo surfaces.
Q9: What should be noted during the use of an air shower?
A:Standard Actions: After entering the air shower, raise both hands and slowly rotate the body 360 degrees while patting clothes during blowing to achieve the best blowing effect.
Strictly Prohibit Forced Door Opening: Double doors are interlocked during blowing; forced pushing or pulling will damage the door lock structure.
Regular Maintenance: Regularly clean primary filters, check fan operation status, and keep the interior clean.
Q10: Why choose Deshengxin air shower?
A:Genuine Materials: Insist on using full-thickness steel plates and high-quality stainless steel, sturdy and durable structure, eliminating shoddy workmanship.
Self-Produced Core Components: Self-produced high-pressure fans and HEPA filters ensure strong wind force and reliable purification effects, while possessing cost advantages.
Exquisite Craftsmanship: Adopting CNC punching, laser cutting, and professional welding processes, the housing is aesthetically pleasing with good sealing.
Comprehensive Service: Provide one-stop service from on-site measurement, solution design, production and manufacturing to installation and commissioning.
