Purchase now: Pfannenberg 11681100055 PTF 60.500 Roof Fan
Purchase now: Atlantech Drives provides you the Pfannenberg 11681100055 (Model: PTF 60.500), a high-efficiency Roof-Mounted Fan designed for vertical heat extraction. In crowded factory layouts where cabinets are bayed together (side-by-side) or placed against walls, side-mounted fans are often not feasible. The PTF 60.500 solves this by mounting on the roof, extracting the rising hot air directly from the top of the enclosure, which is naturally the hottest zone.
Vertical Cooling Efficiency
The PTF 60.500 operates at 230 V AC (50/60 Hz) and provides a powerful airflow of up to 500 m³/h. It uses a high-performance radial fan that is optimized to overcome the static pressure of the internal filter. The housing is made of robust powder-coated steel (RAL 7035) to withstand mechanical impact and environmental stress. The unit is designed to fit the standard 291 x 291 mm cutout, making it compatible with many standard enclosure roof preparations.

Expert Installation Advice: The «Chimney Effect» Mandatory Setup
A roof fan creates negative pressure (vacuum) inside the cabinet. Expert Tip: For the PTF 60.500 to work, you must provide an air inlet at the bottom of the cabinet (e.g., a PFA 60.000 exhaust filter installed as an intake). This setup creates a powerful «Chimney Effect» where cool air enters the bottom, washes over the VFDs and PLCs, and is extracted at the top. Without a bottom inlet, the fan will stall and fail to cool the components.
Frequently Asked Questions (FAQs)
Q: How do I access the filter for maintenance?
A: The PTF series features a tool-less quick-release hood. You can unlatch the top cover to replace the filter mat without opening the main cabinet door, keeping the process safe and fast.
Q: Is it suitable for washdown areas?
A: The standard 11681100055 is IP 33 (rain-proof). For high-pressure washdown areas, you need the optional IP 54 kit or a NEMA 4/4X rated air conditioner instead.
