Data Center & Commercial HVAC Solutions
Why data centers and commercial HVAC are hard on air filtration
Two threats, not one
Particulate loading clogs heat exchangers and raises temperatures; gaseous contaminants corrode the same electronics. A particle filter alone only solves half the problem.
Corrosion is invisible until it fails
Copper and silver corrosion from sulfur and chlorine compounds proceeds quietly. ASHRAE TC 9.9 defines the ISA classification that data halls are expected to meet.
Fan energy is a permanent cost
Filters run continuously for years. Resistance that looks small on a datasheet becomes a significant share of PUE over a full service life.
Filter changes interrupt operations
Every change works against availability. Longer service life and lower change frequency have operational value, not just material value.
Recommended filtration system
Data centers and commercial buildings share the same logic: staged particulate filtration sized for low resistance, plus a gas-phase stage where corrosive gases are present.
| Stage | Typical class | What it captures | Recommended product |
|---|---|---|---|
| Pre-filtration | G4 / ISO Coarse | Coarse dust, pollen | Pleated panel pre-filter |
| Medium filtration | F7–F9 / ISO ePM1 | Fine particles, PM2.5 | Medium-efficiency bag filter |
| Gas phase | Activated carbon | SO₂, NOₓ, H₂S, VOCs | Activated carbon panel or V-bank filter |
| Final (where required) | H13 HEPA | ≥0.3 µm particles | Mini-pleated HEPA filter |
Key control points
- 1Design to the current standards. Test and classify media to ASHRAE 52.2 and ISO 16890; EN 779 is withdrawn and its old classes no longer map directly.
- 2Set a corrosion target. Where the room must meet ISA G1, the gas-phase stage is part of the design, not an upgrade to consider later.
- 3Buy resistance, not just efficiency. Two filters with the same class can differ substantially in pressure drop, and that difference is paid every hour.
- 4Stage the filtration properly. A finer final stage behind a weak pre-filter loads quickly and costs more to own than a well-staged chain.
- 5Instrument the pressure drop. Knowing when a filter is loading lets you schedule changes with operations instead of reacting to an alarm.
Frequently Asked Questions
Is ISO 16890 replacing EN 779?
Yes. EN 779 has been withdrawn and filters are now classified by ISO 16890 into ISO Coarse, ePM10, ePM2.5 and ePM1. Older F5–F9 labels do not translate one-to-one, so compare on the new ratings.
Do data centers need activated carbon filters?
Where corrosive gases are present, yes. Gaseous contamination is a recognised cause of electronics failure, and ASHRAE TC 9.9 sets the corrosion classification that the gas-phase stage exists to meet.
What is ISA G1?
It is a corrosion classification for the data hall environment under ASHRAE TC 9.9, based on measured copper and silver coupon corrosion rates. G1 is the least corrosive class and the usual target for modern facilities.
How can we lower filter-related energy use?
Specify low-resistance media at the required class, keep the staging correct so filters are not overloaded, and avoid over-filtering stages that do not need it.
How often should HVAC filters be changed?
On measured pressure drop against a defined set point, or on the manufacturer’s maximum, whichever comes first. Fixed calendars either change filters too early or too late.
Key Takeaways — Control particles and gases together, specify low resistance at the class you actually need, and change on measured pressure drop. That protects uptime and PUE at the same time.
