Select the appropriate protection class, then assess the dust levels in the environment: if only harmful gases are present, a standard tank will suffice; if dust is also present, an integrated tank should be used. Depending on the filtration level, an integrated filter can verify the dust‑filtering performance.
Select the protection rating, then check the dust level in the environment:
If only harmful gases are present, a standard fuel tank can meet the requirements; if dust is also present, the tank should be integrated. Depending on the filtration level, an integrated filter can verify the dust‑filtering performance:
P1: General particulate filtration efficiency: ≥95.0%;
P2: Medium-capacity filtration efficiency: ≥99.0%;
P3: Higher filtration efficiency: ≥99.99%.
The higher the dust‑proof rating of a filtration unit, the smaller the particle diameter that the dust filter can capture, and the better the filter’s performance.
In summary, when selecting a storage tank, check the type of protection, verify the protection rating, and inspect for dust.
