Cleanroom-Specific Installation, Operation & Maintenance Guide
-
Installation Requirements: The cabinet must be installed in a Class 10-Class 1000 cleanroom, placed on a flat, solid, and level ground, away from air vents, dust sources, and high-humidity areas; ensure that there is at least 15cm of ventilation space around the cabinet to facilitate heat dissipation and nitrogen circulation. Before installation, clean the cabinet body with a cleanroom-specific cleaning agent to remove dust and impurities, ensuring compliance with cleanroom cleanliness requirements.
-
Nitrogen Connection: Connect the cabinet to a stable nitrogen source (purity ≥99.99%), check the airtightness of the connection pipeline to avoid nitrogen leakage; adjust the nitrogen flow rate and positive pressure parameters according to the storage product requirements, and confirm that the pressure and humidity display are normal before putting into use.
-
Daily Operation: After power-on and nitrogen connection, the cabinet will automatically start nitrogen filling until the set positive pressure and humidity are reached, and then enter the constant pressure and constant humidity state. When storing products, wear cleanroom gloves and protective clothing, place the products neatly on the stainless steel shelves, avoid overloading, and close the door tightly after storage to maintain airtightness. Regularly check the nitrogen pressure, humidity display, and alarm function to ensure normal operation.
-
Cleaning and Maintenance: Use cleanroom-specific neutral cleaning agent and soft non-dust cloth to clean the cabinet surface, glass window, and internal shelves every day to avoid dust accumulation; clean the sealing strip regularly to ensure its airtightness. For 316L stainless steel models, avoid using corrosive cleaning agents to prevent damage to the surface.
-
Regular Inspection: Every month, check the nitrogen pipeline connection, pressure sensor, and flow meter for abnormalities; check the door sealing strip for wear, aging, or deformation, and replace it in time. For cabinets with optional molecular sieve dry units, check the regeneration function regularly to ensure normal dehumidification.
-
Special Notes: Do not place flammable, explosive, or corrosive materials in the cabinet to avoid safety hazards; when the nitrogen supply is interrupted, the optional molecular sieve dry unit will automatically start to maintain humidity, and operators should handle the nitrogen supply problem in time. If the cabinet is not used for a long time, cut off the power supply and nitrogen source, clean the internal space, and close the door tightly to prevent dust accumulation.

Frequently Asked Questions (FAQs) for Cleanroom Use
Q1: Why do cleanrooms need stainless steel nitrogen cabinets?
A: Cleanrooms have strict requirements for cleanliness, corrosion resistance, and product protection. Ordinary cabinets are easy to rust, accumulate dust, and cannot meet the dust-free requirements; while stainless steel nitrogen cabinets adopt 304/316L stainless steel, which is dust-free, corrosion-resistant, and easy to clean, and the nitrogen filling function can provide ultra-low humidity and anti-oxidation protection, effectively preventing product contamination, moisture absorption, and oxidation, ensuring product quality and compliance with cleanroom standards.
Q2: What is the difference between 304 and 316L stainless steel, and how to choose?
A: 304 stainless steel has good corrosion resistance and is suitable for general cleanroom scenarios (such as electronic, laboratory cleanrooms); 316L stainless steel has stronger corrosion resistance, high temperature resistance, and acid and alkali resistance, suitable for harsh cleanroom environments (such as pharmaceutical, chemical laboratory cleanrooms, where corrosive reagents or gases may exist). Customers can choose according to the specific environment and stored products.
Q3: Can the nitrogen cabinet maintain the cleanliness of the cleanroom during use?
A: Yes. The cabinet adopts excellent airtight design, which can effectively isolate the internal and external environments, avoiding dust and pollutants in the cleanroom from entering the cabinet, and also preventing nitrogen leakage from affecting the cleanroom environment. At the same time, the stainless steel surface is easy to clean, no dust accumulation, and fully complies with cleanroom cleanliness requirements.
Q4: What is the positive pressure setting for the nitrogen cabinet, and why is it important?
A: The recommended positive pressure setting is 0.01-0.03MPa. Maintaining a positive pressure environment inside the cabinet is crucial because it can prevent external humid air, dust, and pollutants from entering the cabinet through gaps, ensuring the cleanliness and low-humidity environment inside the cabinet, and protecting stored products from contamination and moisture damage.
Q5: Can you provide customized services for cleanroom nitrogen cabinets?
A: Yes. We have independent R&D and production teams, which can provide comprehensive customized services according to the specific needs of cleanrooms: optional 304/316L stainless steel, customize cabinet capacity (beyond 98L-1436L), adjust nitrogen flow and pressure parameters, add ESD anti-static function, molecular sieve dry unit, or humidity data recording function, fully matching the specific requirements of different cleanroom industries and scenarios.
