**A:** All our blowers are oil-free and maintenance-free.
- **Q:** Can I pump combustible gas through my blower?
**A:** For such applications, we recommend our explosion-proof ATEX blower (customized).
- **Q:** Are the foam pieces inside my blower for filtration?
**A:** No, they are for sound reduction. An inlet filter should be purchased separately.
- **Q:** What happens if I don’t use a relief valve on my blower?
**A:** The blower may overheat, leading to thermal expansion of internal components, which could damage the impeller and bearings.
