ZJNF Factory Cargo Air Shower For Removing Dust Particles Cleanroom

‌How to Choose the Right Air Shower for a Cleanroom‌

Selecting an cargo air shower for a cleanroom requires careful consideration of its core functions, material compatibility, automation features, and installation specifications. Below is a detailed guide to help you make an informed decision.

‌1. Determine Cleanroom Class and Filtration Requirements‌

The primary function of an air shower is to remove dust particles from the surface of goods. Its filtration efficiency must match the cleanliness level of your cleanroom:

• ‌HEPA Filters‌: Suitable for cleanroom classes ranging from Class 10,000 to Class 100,000, with a filtration efficiency of ≥99.97% for particles ≥0.3 μm. For higher cleanliness levels (e.g., Class 1,000 or better), consider ‌ULPA filters‌.
• ‌Filtration System Configuration‌: A three-stage filtration system (pre-filter, medium-efficiency filter, and HEPA/ULPA filter) is recommended to prolong the life of the HEPA filter and ensure optimal performance.

‌2. Select the Right Material and Cabinet Design‌

Stainless steel is the preferred material due to its durability and corrosion resistance. Choose based on your environment:

• ‌304 Stainless Steel‌: Ideal for standard cleanroom environments, offering a good balance of cost and corrosion resistance.
• ‌316L Stainless Steel‌: Recommended for harsh conditions (e.g., high humidity, chemical exposure, or food/chemical industries) due to superior corrosion resistance.
• ‌Cabinet Design‌: Ensure airtight sealing with gaskets or seals to prevent unfiltered air from entering the cleanroom.

‌3. Prioritize Automation Features‌

Automation enhances efficiency and reduces contamination risks:

• ‌Sensor Control‌: Equipped with infrared or radar sensors for automatic activation when objects are detected.
• ‌Interlock System‌: Dual-door electronic interlocking ensures only one door is open at a time, preventing cross-contamination.
• ‌Adjustable Settings‌: Customizable air velocity and shower duration to accommodate different load sizes and cleanliness requirements.

‌4. Follow Installation and Maintenance Guidelines‌

• ‌Installation‌: Ensure a level, load-bearing surface (minimum 1.2x the unit’s weight). Leave at least 20 inches (50 cm) of clearance around the unit. Seal all gaps to maintain airtightness.
• ‌Maintenance‌: Regularly clean or replace pre-filters (every 3–6 months). HEPA filters typically last 1–3 years, depending on usage and environmental conditions.
