What IP55 Means
IP55 means dust-protected (limited ingress won't impair operation) plus water-jet resistant. For outdoor and dusty enclosures, it is the baseline rating.
Challenges in Dusty Sites
- Dust on fins drops heat exchange;
- Metal powder is conductive and explosible;
- Clogged filters cut airflow faster.
| Env. | Advice | Service |
|---|---|---|
| Normal dust | Std filter | 3–6 mo |
| Metal powder | High-density+seal | 1–3 mo |
| Cement | Pre-filter | Monthly |
Protection & Filtration
Units use sealed ducts and washable filters with dust grilles. See products page for options or contact us for conditions.
Upkeep
- Blow fins and replace filters on schedule;
- Check seal strips for aging;
- Shorten interval in heavy dust.
