Proton® T-4™ Hard Drive Degausser

The NSA listed T-4 utilizes patented “Reverse Polarity” technology to produce a bi-directional
field of at least 20,000 Gauss positive and 20,000 Gauss negative per cycle. This proprietary
technology creates the highest flux field of any degausser available and ensures permanent
erasure of the highest coercivity media available today. It is also projected to handle future
media technology for years to come. Other degaussers may have either a positive or negative
pulse, but not both; this technology is unique to the T-4. There is also no drawer to open and
close, which reduces operator handling and increases efficiency.
