HPM-4E Degausser

The HPM-4E degausser combines a set of two unique and very powerful magnet pairs with the speed of an industrial hand crank. Large chamber accepts larger form factor hard disk drives (HDDs) without disassembly or adaptors. By generating fields in multiple directions, it is possibly your best defense against current Longitudinal Magnetic Recorded (LMR) and future Perpendicular Magnetic Recorded (PMR) hard disk media. Simply insert the media into the drawer and rotate the effortless handle. The media is pulled inside the degausser where it passes a shielded permanent magnet that completely sanitizes the media.


  • Quick cycle time allows for fast throughput (erase up to 900 hard drives/tapes per hour).
  • Oversized chamber erases larger HDD form factors, like 3.5” drives measuring up to 1.63” in height.
  • Listed in the "NSA Evaluated Products List – Degausser."

HPM-4E Performance

Independent scientific testing confirms this degausser erases Longitudinal Magnetic Recorded (LMR) and Perpendicular Magnetic Recorded (PMR) hard disk media with a coercivity of 5000 Oersteds and tape media with a coercivity of 2800 Oersteds.

*Erasure performance testing on hard disks with coercivities above 5000 Oe and on magnetic tapes 2800 Oe and above in progress.

The patented, dual permanent magnet arrangement of the HPM-4E degausser creates multiple magnetic fields working in a vertical and horizontal pattern, which results in two extremely powerful magnetic fields. Independent scientific testing confirms the HPM-4E erases all current magnetic media, as well as having the potential to erase higher coercivities as they become available, making the HPM-4E a smart, long-term choice.

With permanent magnet technology, the HPM-4E operates continuously in powerless environments without contributing to your carbon footprint. Simply insert the media and rotate the handle. No electricity required.
