Product Overview: Pfannenberg 1337849 Rainhood
The Pfannenberg 1337849 is a high-grade Stainless Steel Rainhood engineered specifically for the PF 11.000 and PF 22.000 Filterfan series, as well as their corresponding exhaust filters (PFA 10.000/20.000). This industrial accessory is essential for protecting electrical enclosures located in harsh outdoor environments or areas subject to high-pressure wash-downs. By installing the 1337849, the ingress protection of the cooling system is elevated to IP56, safeguarding internal electronics from wind-driven rain, snow, and direct water sprays.
Unmatched Durability and Environmental Protection
Constructed from high-quality AISI 304 stainless steel, the 1337849 rainhood is designed to resist corrosion in chemical, maritime, and food processing environments. It features a robust design that prevents foreign objects and liquids from entering the Filterfan while maintaining optimal airflow dynamics. The hood includes a high-durability silicone seal that ensures a tight fit against the enclosure surface, maintaining the cabinet’s NEMA 4X integrity. Its design also facilitates easy maintenance, allowing for filter mat replacements without requiring the full removal of the hood structure.

Industrial Reliability and Safety Compliance
The 1337849 is built for the rigors of 24/7 industrial duty. It is particularly effective in preventing «water pooling» around the fan intake, which can lead to moisture ingress during thermal cycling. By choosing Pfannenberg genuine accessories, you ensure full compliance with UL and CE safety standards for outdoor enclosure configurations. This «fit and forget» component is the premier choice for infrastructure, oil & gas, and renewable energy projects.

Frequently Asked Questions
Does this affect the fan’s airflow? The 1337849 is flow-optimized, but a slight derating (approx. 10%) should be considered during thermal calculations. Can it be used on plastic enclosures? Yes, provided the mounting surface is flat and the cutout matches the PF series specifications.
