Purchase now: Atlantech Drives provides you the Pfannenberg 11681102055 (Model: PTF 60.500), a high-performance Roof-Mounted Filterfan designed for industrial enclosures where door or side-wall mounting is impossible due to space constraints. In crowded factory floors, the top of the cabinet is often the only available space for thermal management. The PTF 60.500 leverages the laws of physics—specifically that hot air rises—to extract heat directly from the «hot zone» at the very top of the enclosure, providing exceptional cooling efficiency.
Technical Specifications and Vertical Extraction
The PTF 60.500 operates at 230 V AC (50/60 Hz) and delivers an unimpeded airflow of approximately 500 m³/h. It features a robust metal housing cover finished in RAL 7035 (Light Gray), which provides mechanical protection against falling debris. The internal high-performance radial fan is designed to overcome the static pressure of the G4 filter mat while maintaining a low noise profile.

Expert Installation Advice: The «Passive Intake» Strategy
Since the PTF 60.500 sucks hot air out of the top, you must provide a path for cool air to get in. Expert Tip: Install an inlet filter (like the PFA 60.000) at the very bottom of the enclosure door. This creates a powerful vertical draft (Chimney Effect) that sweeps cool air across the entire height of the backplane, cooling VFDs and power supplies more effectively than side-mounted fans which might leave hot pockets at the top.
Frequently Asked Questions (FAQs)
Q: Is it waterproof?
A: The standard unit is rated IP 33, which protects against vertical rain. For washdown areas, you must use the optional protection kit to achieve IP 54.
Q: How do I change the filter on the roof?
A: Pfannenberg designed the PTF series with maintenance in mind. The metal hood unlatches easily from the top (tool-less access), allowing you to swap the filter mat without opening the electrical cabinet below.
