Technical Specifications and Construction
The 1337853 is constructed from high-quality AISI 304 (1.4301) Stainless Steel. This material offers excellent resistance to general industrial corrosion and oxidation. The hood features a deep-drawn, flow-optimized design that covers the large 291x291mm cutout fans without choking the airflow. It includes a specialized silicone sealing frame that ensures a watertight fit against the enclosure wall, preventing moisture ingress even during heavy storms.

Expert Installation Advice: Wind Load Management
Due to the large surface area of this hood (covering high-capacity fans), it can be subject to significant wind loads in outdoor installations. Expert Tip: Ensure that the mounting surface of the cabinet is rigid. When installing on a thin-walled enclosure door, consider using a reinforcement plate on the inside to prevent the sheet metal from flexing, which could compromise the silicone seal over time.
Frequently Asked Questions (FAQs)
Q: Can I access the filter for maintenance?
A: Yes, the design allows for access to the underlying filterfan grille from the bottom, permitting filter mat changes without removing the heavy stainless steel hood.
Q: Is 304 steel enough for coastal areas?
A: For direct coastal exposure (salt spray), we recommend the 1337855 (316L) version. The 1337853 (304) is best for general industrial and inland outdoor use.
