Detailed Description
ATMCU is designed for continuous operation in high-temperature clean processes where standard HEPA filters fail. Its all-inorganic construction (stainless steel + glass) eliminates organic outgassing that could contaminate sensitive processes, making it the filter of choice for depyrogenation tunnels in pharmaceutical manufacturing.

Applications
- Depyrogenation tunnels in pharmaceutical cleanrooms - High-temperature clean ovens for sterile component manufacturing - Terminal filtration in high-temperature process equipment - Power generation and nuclear facility HVACSelection Notes
- **150 mm (Q) depth** — choose when installation space is limited or the airflow demand is moderate. - **290 mm (P) depth** — choose when maximum airflow per unit face area is required, or when extended service life matters (larger dust-holding capacity). - Scan-testable as standard; leak-free versions available on request. - Replace when pressure drop reaches 500 Pa (2× initial) or per site maintenance schedule.Selection References
Before ordering, verify the efficiency grade, media type, and whether the operating environment fits your requirements.
