Sold Out


The FN3S is a 3-fan cooling unit ideal for audio professionals and sound engineers looking to safeguard equipment in their sound rack from heat and dust damage. For maximum protection, the FN3S pumps out a whopping 324 cubic feets of air per second to remove hot air before it builds up. An integrated temperature sensor and front facing digital display also provide live feedback about the fans’ temperatures to provide an early warning about potential problems. In addition, the fans’ signature ULTRA QUIET design helps keep them from interfering or causing noise distraction.

The FN3S comes in standard 19” audio rack dimensions and features integrated rack mounting brackets on both sides. In addition, the FN3S takes up just 2.5 units of space to help reduce space usage. With high quality components, a rugged design, and meticulous construction, the FN3S will be a focal part of your audio setup for many shows to come.
