Purchase now: Atlantech Drives provides you the Pfannenberg 11642103055 (Model: PF 42.500), a robust mid-range 230V AC Filterfan. This unit is the perfect «middle ground» solution for industrial enclosures that are too large for the compact PF 22.000 but do not require the massive airflow of the PF 66.000. It is widely used in machine tool control panels, packaging machinery, and moderate-power distribution boards.
Optimized Airflow and Energy Efficiency
The 11642103055 delivers an unimpeded airflow of approximately 150 – 170 m³/h. It utilizes a 223 x 223 mm cutout (which it shares with the more powerful PF 43.000, offering an easy upgrade path). The unit features a flow-optimized rotor that minimizes noise while maximizing static pressure capabilities. The integrated G4 fluted filter mat ensures that the air entering your cabinet is clean, protecting sensitive electronics from conductive dust and debris.

Maintenance Expert Tips: The 223mm Standard
The 223mm cutout is a standard in the industry. Expert Tip: If you are retrofitting an older cabinet that used a different brand (like Rittal TopTherm or Hoffman), check the cutout dimensions carefully. The Pfannenberg «Click & Fit» system is forgiving and can handle sheet metal thickness from 1mm to 3mm, but the hole must be square. This fan is an excellent retrofit choice due to its low installation depth, leaving more room for internal cable ducts.
Frequently Asked Questions (FAQs)
Q: What is the difference between PF 42.500 and PF 43.000?
A: They use the same housing and cutout (223mm). The PF 43.000 has a more powerful motor and delivers higher airflow (~270 m³/h) compared to the PF 42.500 (~160 m³/h).
Q: Is the filter mat washable?
A: We recommend replacing the G4 mat (Part 18611600032) rather than washing it, as washing degrades the fiber structure and reduces filtration efficiency.
