Product Overview

AFK 100 (10 pack), part number 70-1341-01. The Extron AFK 100 is a replacement air filter kit for Extron Ultra FX Series power amplifiers, supplied in a 10 pack for scheduled preventive maintenance. Amplifier filters load with dust over time, and restricted airflow drives internal temperatures up, which shortens component life and can trigger thermal protection during high-demand events. Ordering by the ten-pack matches how maintenance actually happens, one service visit covering a rack or a building rather than one amplifier at a time. It is a consumable, not a repair part.

Product Description

Filter replacement is the least glamorous line item in an AV service agreement and one of the most consequential. A rack-mounted amplifier pulling air through a clogged filter runs hotter at every power level, and the failure it eventually produces looks like an amplifier fault rather than a maintenance lapse.

The AFK 100 supplies replacement filters for Extron Ultra FX Series amplifiers in packs of ten. That quantity is deliberate: service visits cover multiple amplifiers, and having filters on the truck for the whole rack avoids a second trip. For facilities managing amplifiers across several buildings, ordering by the pack keeps a maintenance stock on the shelf.

Replacing filters on schedule maintains the airflow the amplifier was designed around, which keeps thermal headroom available for the loud passages that actually matter. In venues with high particulate loads, such as gymnasiums, houses of worship with heavy foot traffic, or facilities under construction, the replacement interval should be shorter than the manufacturer baseline.

The AFK 100 is compatible with Extron Ultra FX Series power amplifiers, including the NetPA U Series FX models. Confirm your specific amplifier model against Extron's compatibility list before ordering.
