## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are available for filter frames in machinery manufacturing?
**A**: Filter frames are typically constructed from galvanized steel, aluminum, or stainless steel, each offering different benefits for corrosion resistance, weight, and durability in industrial environments.

### Q: How does a filter frame ensure proper sealing in a HEPA filter bank?
**A**: The filter frame includes a seal gasket that creates an airtight seal between the frame and filter media, preventing air bypass and ensuring maximum filtration efficiency in HEPA systems.

### Q: What are the main components of a filter frame assembly?
**A**: A complete filter frame assembly consists of three main components: the frame body for structural support, the media support grid that holds the filter material, and the seal gasket that ensures airtight operation.
