Extron AFK 100 (part number 70-1341-01) — a ten-pack of air filters for Extron Ultra FX series power amplifiers.

Extron lists this part as the Air Filter Kit for Ultra FX Amps, supplied ten to a kit. The Ultra FX amplifiers it serves are fan-cooled, drawing air front-to-rear through a variable-speed fan, which is what lets them sit in a rack with no empty slot above or below for ventilation. That airflow path is only as good as the filter in front of it, so keeping a stock of spares on the shelf is the difference between a scheduled swap and an over-temperature callout.

Key Capabilities

• Ten air filters supplied per kit under a single Extron part number, 70-1341-01
• Made for the Extron Ultra FX amplifier family, including the XPA U 2008 FX
• Genuine Extron part rather than a generic cut-to-fit filter medium
• Supports the front-to-rear variable-speed fan cooling path used by Ultra FX amplifiers
• Kit quantity suits multi-amplifier racks and estate-wide maintenance schedules

Where It Is Used

Anywhere Ultra FX amplifiers are racked and running continuously: campus and stadium paging racks, house-of-worship and auditorium amp rooms, corporate headend closets, and multi-zone retail or hospitality systems. Facilities teams typically hold a kit per rack so filters can be changed on a planned maintenance visit.
