Why a standard vacuum does more harm than good in a data center, and what HEPA, ULPA and ESD-safe actually mean.
A standard commercial vacuum collects the large debris you can see and exhausts much of the fine dust you cannot see straight back into the room. In an office that hardly matters. In a data center, that fine dust is exactly what you are trying to remove.
HEPA filtration
A true HEPA filter captures at least 99.97% of particles at 0.3 µm — the size that is hardest to filter. Larger and smaller particles are captured even more efficiently. This is the baseline for any vacuum used in white space.
ULPA filtration
ULPA filters go further, capturing 99.999% of particles at 0.12 µm. They are used in the most sensitive areas and for work such as zinc whisker remediation, where the particles being removed are especially harmful.
ESD-safe construction
Dust moving at speed through a plastic hose builds up static charge. An ESD-safe vacuum uses static-dissipative hoses and tools and a grounding path, so that charge drains away safely instead of discharging into the nearest metal surface — which, in a data center, may be a cabinet full of equipment.
The rest of the kit
- Backpack HEPA vacuums for overhead trays and cabinet tops
- Low-lint, microfiber and cleanroom wipes
- Neutral, residue-free cleaning solutions approved for the space
- Suction tile lifters for raised floors
- A calibrated laser particle counter to measure the result
