Frequently Asked Questions (FAQ) - Ventilated Locker Procurement

1. Q: How does this ventilated locker help maintain our cleanroom's ISO classification?
A: This locker acts as a local exhaust point for contamination. By connecting it to your facility's exhaust system, it creates a constant negative pressure inside the locker. This actively pulls particles, skin flakes, and fibers shed from stored clothing or items out of the cleanroom environment instead of allowing them to circulate. This source containment strategy is a highly effective way to protect your room's air quality and ISO classification.

2. Q: Can the locker be customized to fit our specific room layout and number of users?
A: Absolutely. SUN-YEE TECH specializes in customization. We can alter the overall dimensions (height, width, depth), change the number of compartments (e.g., a 12-locker unit), and configure the exhaust duct connection position (top, side, or rear) to suit your room's plumbing and layout. We can also adjust the door perforation pattern and percentage to achieve specific airflow requirements.

3. Q: What is the required airflow or static pressure for this locker to function correctly?
A: For optimal performance, we recommend an exhaust airflow rate of approximately 50-100 CFM (25-50 L/s) per locker compartment. The external exhaust system should provide a slight negative static pressure (typically -0.1 to -0.2 inches of water column) at the duct connection point to ensure contaminants are effectively drawn out. Our technical team can provide specific calculations based on your final configuration.

4. Q: What material grade do you recommend, 304 or 316 stainless steel?
A:

• Grade 304 SS: Suitable for most standard cleanroom and general laboratory environments. It offers excellent corrosion resistance, durability, and ease of cleaning.

• Grade 316 SS: We recommend this "marine-grade" stainless steel for environments exposed to more aggressive chemicals, solvents, high humidity, or chlorides (e.g., in pharmaceutical processing or coastal areas). It provides superior resistance to pitting and corrosion.

5. Q: What is included in the delivery, and do you provide guidance for connecting it to our HVAC?
A: Each locker is shipped fully assembled or in minimal sub-assemblies for easy installation. The package includes the locker, all necessary mounting hardware, and a detailed installation manual with diagrams. While connection to the building's HVAC exhaust duct is the client's responsibility, we provide comprehensive technical data sheets with flange dimensions, airflow requirements, and connection specifications to guide your facility's engineer or contractor seamlessly.
