Anping County Boli Hardware Wiremesh Products Factory proudly presents our high-quality Fan Inlet/Outlet Guard Screen with Flange Mount, crafted from premium 304 stainless steel. With over two decades of manufacturing experience since 1998, we have engineered this guard screen to deliver reliable protection for fan systems while ensuring effective fine particle filtration. The combination of a 0.9mm wire diameter and 4mm mesh opening strikes an optimal balance between airflow resistance and particle blocking, making it ideal for industrial, commercial, and HVAC applications.
Key Features & Technical Specifications
- Material: 304 stainless steel — excellent corrosion resistance, durability, and suitability for harsh environments (e.g., outdoor, chemical, food processing).
- Wire Diameter: 0.9mm — strong enough to withstand impact and pressure, yet fine enough to maintain precise mesh openings.
- Mesh Opening: 4mm — effectively blocks particles larger than 4mm (e.g., dust, debris, insects, and small foreign objects) while allowing maximum airflow.
- Flange Mount Design: Pre-drilled flange for easy and secure installation on fan inlet/outlet ducts, enclosures, or equipment. No additional brackets required.
- Fine Particle Filtration: Suitable for pre-filtering in ventilation systems, engine cooling fans, compressor intakes, and electronic cabinet cooling.
- Customizable: Available in various sizes, shapes, and additional surface treatments (e.g., powder coating, electro-polishing) upon request.

Frequently Asked Questions (FAQ)
-
Q: What is the material of the guard screen?
A: The guard screen is made of 304 stainless steel, which offers excellent corrosion resistance and durability. Other materials (e.g., 316 stainless steel, galvanized steel) are available upon request. -
Q: Can I get custom sizes?
A: Yes, we offer customization for dimensions, shape, and flange hole patterns. Please provide your required specifications for a quote. -
Q: How is the screen installed?
A: The screen features a pre-drilled flange that can be bolted or screwed directly onto the fan inlet/outlet duct or housing. It is a simple mechanical fastening process. -
Q: What is the mesh opening size?
A: The standard mesh opening is 4mm (square). This allows effective blocking of particles larger than 4mm while maintaining good airflow. -
Q: Is this screen suitable for outdoor use?
A: Yes, 304 stainless steel is highly resistant to weather and UV radiation, making it suitable for outdoor environments. For coastal or highly corrosive areas, 316 stainless steel is recommended. -
Q: Can the screen be used for high-temperature applications?
A: The screen can withstand intermittent temperatures up to 300°C. For continuous high-temperature use, please consult our technical team for material recommendations. -
Q: What is the wire diameter, and why is it important?
A: The wire diameter is 0.9mm, which provides a strong yet flexible structure. It prevents deformation under pressure and ensures the mesh retains its shape over time. -
Q: Do you offer surface treatments like powder coating?
A: Yes, we can provide additional surface treatments such as powder coating, electro-polishing, or passivation upon request. The standard finish is mill finish.
