Purchase now: Atlantech Drives provides you the Pfannenberg 11843151055 (Model: PFA 40.000), the dedicated Exhaust Filter designed to pair with the PF 42.500 and PF 43.000 Filterfan series. In any forced convection cooling system, the exhaust is just as critical as the intake. The PFA 40.000 facilitates the efficient exit of hot air from the enclosure while maintaining the IP 54 / NEMA Type 12 protection rating, ensuring that the cabinet pressure remains neutral and dust does not enter through the exhaust path.

Expert Installation Advice: Avoiding Thermal Short Circuits
A common mistake is placing the exhaust filter too close to the intake fan. Expert Tip: Always maximize the vertical distance between the intake (PF 42.500) and this exhaust filter (PFA 40.000). If they are too close, the cool air will exit before cooling the components (short cycling). Ideally, place the PFA 40.000 on the opposite wall or the top of the door to force the air to travel diagonally across the heat-generating drives.
