Buy now: Atlantech Drives provides you the Pfannenberg 1337855, the ultimate protective accessory for high-capacity cooling systems in extreme environments. This is the AISI 316L (V4A) Stainless Steel variant of the large rainhood, designed specifically for the PF 65.000, PF 66.000, and PF 67.000 series. It is the mandatory choice for offshore oil platforms, wastewater treatment plants (high H2S), and coastal facilities where standard steel would fail due to pitting corrosion.
Superior Material Science: Why 316L?
The 1337855 is fabricated from 316L grade steel, which contains molybdenum. This addition drastically increases resistance to chlorides (salt) and acids. By installing this hood, your enclosure achieves NEMA Type 4X and IP 56 protection, ensuring that the sensitive fan electronics and the internal cabinet components are shielded from driving rain, salt spray, and corrosive chemical vapors.

Expert Maintenance Advice: Preventing Galvanic Corrosion
When installing a 316L hood, you must ensure that the mounting hardware is compatible. Expert Tip: Always use the supplied 316L screws. If you use standard zinc-plated screws or 304 screws in a high-salinity environment, you risk galvanic corrosion that will seize the fasteners and stain the hood. Periodically washing the hood with fresh water removes salt deposits and maintains the passive protective layer of the steel.
