NIPPON MUKI
ATMOS ATML Standard HEPA Filter
Product Overview
ATML is Nippon Muki’s mini-pleats standard HEPA filter with 99.99% efficiency @ 0.3 μm. Separator-free construction drops pressure drop by 50-60% vs ATMC — the preferred filter for energy-efficient FFUs and laminar/turbulent terminal filtration.
Key features
・HEPA 99.99% @ 0.3 μm
・Mini-pleats construction (ultra-low PD)
・PD 50-60% lower than ATMC
・Ideal for cleanroom ceiling FFUs

Detailed Description
ATML is the mini-pleats version of ATMC. Dense pleating doubles effective filter area, so PD at the same airflow drops dramatically — directly reducing FFU fan power and noise.

Airflow vs Pressure Drop (representative)
Applications
- Cleanroom ceiling FFU terminals - Laminar / turbulent flow terminal filtration - Energy-efficient AHU systemsSelection Notes
- Maximum airflow → ATMC (separator type). - Low PD / energy efficiency → ATML (this model). - Low-boron → BGML; low-organic + low-boron → TGML.Selection References
Before ordering, verify the efficiency grade, media type, and whether the operating environment fits your requirements.
