Frequently Asked Questions (FAQ)
-
Q: Is the 200mm diameter the outer diameter or inner diameter?
A: The 200mm refers to the overall outer diameter of the guard screen, designed to fit over a 200mm fan inlet opening. The actual inner opening may be slightly smaller due to the wire mesh structure. -
Q: Can I get a custom mesh size for better airflow?
A: Yes, we offer customizable mesh openings, wire thicknesses, and shapes. For example, larger openings (e.g., 15mm) increase airflow but reduce protection level. We can suggest the optimal balance for your application. -
Q: Is this guard screen suitable for outdoor use?
A: Absolutely. 304 stainless steel provides excellent corrosion resistance, making it ideal for outdoor HVAC units, exhaust fans, and rooftop installations. For extremely corrosive environments, we offer 316 stainless steel option. -
Q: Does the guard screen come with mounting hardware?
A: The standard product does not include screws or clips. It is designed with a flat rim that can be easily attached using your own fasteners or brackets. Customized edge treatments (e.g., pre-drilled holes) are available upon request. -
Q: What is the minimum order quantity (MOQ)?
A: For standard 200mm 304 stainless steel guard screens, our MOQ is 100 pieces. For custom sizes or finishes, MOQ may vary – please contact us for details. -
