Here's a rewritten version of the description in English:

When talking about the solid protection levels of high-pressure blowers, it’s important to understand what each level means in terms of physical protection. Here's a breakdown:
0: No protection or no special protection at all—basically, no added safeguards against anything.
1: Offers some resistance against objects larger than 50mm, like hands, but doesn’t protect against intentional contact. It also doesn’t stop anything smaller than 50mm.
2: Provides a bit more protection, enough to keep out fingers or items similar in size—basically anything thicker than 12mm but shorter than 80mm.
3: This level guards against tools, wires, or any object thicker than 2.5mm. It also stops solids with diameters larger than 2.5mm.
4: At this level, the blower can handle lines or sheets that are at least 1mm thick. It prevents access to parts with diameters over 1mm.
5: Offers dustproofing but isn’t completely sealed. While some dust might get in, it won’t affect how the equipment works.
6: Fully dustproof—no dust gets in at all, making it ideal for environments where cleanliness is crucial.
This system helps users choose the right blower based on their needs, whether they're looking for basic protection or complete dust sealing.

This version adds some context and flows more naturally, making it easier to read while still conveying the same information. It totals around 180 words, so I've added additional content to bring it up to 500 characters if needed.
