What Noise Reduction Can I Expect from Orion Acoustic Quiet Rackmount Cabinets?
Comparing Manufacturers' claims for noise reduction can be very misleading because of widely differing test methods.
Also, enclosures with similar decibel noise-reduction ratings may sound very different to the human ear, as some acoustic racks dampen the more noticeable noise frequencies better than others.
To help you make an informed choice we have independently tested all the Quiet Rack ranges side by side enabling us to recommend the right Quiet Rack to meet your needs. You are also welcome to compare the racks for yourself in our unique Quiet Rack Demo Room.

Orion's Acoustic Rack provides a cost effective solution for noisy servers and network equipment in a wide range of heights and depths. These Orion Quiet Racks are competitively priced and deliver a surprisingly effective noise reduction performance.
Additional attractions of the Orion range are dust filtering as standard (IP54) as well as the wide choice of sizes. The mini range has a glass 'window' in the front door as standard, and is available as an option for the larger standard sizes for a small additional charge.
All Orion Acoustic Cabinets come with inbuilt quiet fans (see below).
