In an era where data privacy regulations are increasingly stringent, data destruction is no longer optional for enterprise IT operations. When decommissioning magnetic media, simple formatting or file deletion is insufficient—data can still be recovered using advanced digital forensic techniques.

To guarantee permanent sanitization, organizations turn to degaussing as a core pillar of their IT Asset Disposition (ITAD) and E-waste management strategies.

How Degaussers Work: The Principle of Magnetic Sanitization

A degausser works by exposing magnetic storage media—such as traditional hard disk drives (HDDs) and magnetic tapes—to a powerful, controlled magnetic field.

Magnetic media stores data in tiny magnetic domains aligned in specific patterns representing binary code (1 & 0). A degausser neutralizes these magnetic fields, randomizing the alignment of the domains entirely. This process completely erases all data, metadata, and low-level formatting instantly, rendering the storage media permanently unreadable and impossible to reuse.

Key Degausser Comparison Factors

When evaluating degaussers for enterprise or forensic workflows, key considerations include magnetic field strength, simultaneous batch capacity, supported media types, and compliance certifications.

1. Magnetic Field Intensity & Regulatory Compliance

The strength of a degausser's magnetic field is measured in Oersteds (Oe). Higher coercivity media requires stronger magnetic fields to ensure total destruction.

MagWiper NSA Degausser: Generates a powerful ~20,000 Oe magnetic field. It is officially NSA EPL Listed, making it the ideal choice for government agencies, defense contractors, and high-security enterprises requiring top-tier compliance.
MagWiper MW Series (MW-15X, MW-25X, MW-30X): Generate a robust ~10,000 Oe magnetic field. These units deliver complete, highly effective sanitization for standard corporate HDDs, tapes, and legacy media.

2. Simultaneous Processing Capacity

Depending on your throughput requirements—ranging from ad-hoc single-drive disposal to massive ITAD recycling operations—batch capacity is a critical efficiency factor.

Degausser Model	3.5" HDD	2.5" HDD
MagWiper NSA Degausser	1 unit	8 units
MagWiper MW-15X Degausser	1 unit	6 units
MagWiper MW-25X Degausser	2 units	10 units
MagWiper MW-30X Degausser	14 units	51 units

**MagWiper MW-25X Degausser** – Erases 3.5" HDDs with mounting brackets.

3. Supported Media Types

While all models handle standard hard drives, larger-chamber units accommodate specialized tape Form Factors and even entire devices.

Degausser Model	Erasable media
MagWiper NSA Degausser	Hard disk: 2.5” HDD, 3.5” HDD Magnetic tape: LTO, DDS/DAT, AIT
MagWiper MW-15X Degausser	Hard disk: 2.5” HDD, 3.5” HDD Magnetic tape: LTO, DDS/DAT, AIT
MagWiper MW-25X Degausser	Hard disk: 2.5” HDD, 3.5” HDD (with mounting bracket) Magnetic tape: LTO, DDS/DAT, AIT, VHS
MagWiper MW-30X Degausser	Hard disk: 2.5” HDD, 3.5” HDD (with mounting bracket) Magnetic tape: LTO, DDS/DAT, AIT, VHS Laptop: Sizes up to B4

**MagWiper MW-30X Degausser** – Erases entire laptops up to B4 size.
