Purchase now: Atlantech Drives provides you the Pfannenberg 11843101055 (Model: PFA 40.000), the essential Exhaust Filter component for Pfannenberg’s mid-to-large cooling systems. Designed to match the airflow characteristics of the PF 42.500 and PF 43.000 Filterfans, this unit ensures that hot air is expelled from the enclosure efficiently while maintaining the necessary static pressure to keep dust out. It is a mandatory accessory for any forced ventilation setup requiring NEMA 12 / IP 54 protection.
Optimized Airflow and G4 Filtration
The 11843101055 fits the standard 223 x 223 mm cutout. It features the 4th Generation «Click & Fit» mounting system, which utilizes high-tension snap mechanisms to seal the unit against the enclosure wall without screws (for wall thickness 1-4 mm). The integrated G4 fluted filter mat provides a 300% larger filtration surface area than flat mats, reducing air resistance and extending the time between maintenance cycles.

Maintenance Expert Tips: Airflow Balancing
Engineers often forget that a clogged exhaust filter restricts the intake fan just as much as a clogged intake filter. Maintenance Advice: When you replace the mat on your PF 43.000 intake fan, always replace the mat on the PFA 40.000 exhaust filter at the same time. A blocked exhaust creates backpressure that stalls the intake fan, reducing cooling capacity by up to 60% and causing the fan motor to run hotter.
Frequently Asked Questions (FAQs)
