Pfannenberg PF 22.000 Series High Air Flow Filter Fan, 230V AC/DC, IP54, 145 mm x 145 mm PF 22.000

Pfannenberg PF 22.000 Series filter fan PF 22.000 is designed for high airflow performance in demanding industrial applications. Operating at 230V AC/DC with an IP54 rating, this filter fan ensures reliable enclosure ventilation and protection in machinery and electrical cabinets.

The advanced pleated fabric filter combined with a unique louvre design delivers exceptional air flow while maintaining robust filtering for dust and moisture. The patented pre-separation lamellas prevent most water and dust from reaching the filter mat, thereby extending service intervals and reducing maintenance requirements.

The “Click and Fit” mechanism provides a secure, hardware-free installation and simplifies filter mat changes for increased user convenience. The patented four-corner fastening system secures the fan module firmly and includes a cage clamp terminal that can rotate 90 degrees to accommodate various wiring directions.

The filter fan units are fully reversible, allowing them to be configured to introduce or exhaust air from enclosures, making them versatile for HVAC and industrial thermal management use. Designed with compatibility in mind, the cutouts align with previous Pfannenberg generations and leading competitors, facilitating easy replacement and upgrades.

This filter fan series complies with multiple standards including EN 60529, NEMA type 12, UL 50, cUL approval, EN ISO 3741, and EN 779, ensuring quality and safety. Its sleeve bearing and flatpack housing provide durable operation with low noise levels (44 dBA).

Typical applications include HVAC systems, electrical enclosures in automation, control cabinets, and industrial manufacturing environments where effective dust and moisture protection is critical.
