### FAQs:
**Q: Can water be pumped through my blower?**
**A:** No, only clean dry air is suitable for this blower.
**Q: My blower is leaking around the cover. Is that normal?**
**A:** Standard blowers are not designed to be completely leak-proof. If you require a leak-proof version, we offer special customized options.
**Q: What kind of oil do I need for my blower?**
**A:** All our blowers are oil-free and maintenance-free by design.
**Q: Can I pump combustible gas through my blower?**
**A:** For combustible gas applications, we recommend our **explosion-proof ATEX blower** (customized option).
**Q: Are the foam pieces inside my blower for filtration?**
**A:** No, they are used for **noise reduction**. An inlet filter should be sourced separately.
**Q: What happens if I don’t use a relief valve?**
**A:** Without a relief valve, the blower may overheat, leading to thermal expansion of internal parts, which could damage the impeller and bearings.
