ATMOS ATMPK Low-Pressure-Drop HEPA Filter
Product Overview
ATMPK is a V-shape pack HEPA filter with 99.97% efficiency @ 0.3 μm. The V-geometry dramatically increases media surface per footprint — up to 4200 CMH per unit with low pressure drop. Ideal for AHU systems handling large centralized airflow.
Key features
・V-shape pack design (huge filter area)
・HEPA 99.97% @ 0.3 μm
・Up to 4200 CMH per unit
・Ultra-low PD and extended service life
Target industries:Medical, Pharmaceutical

Applications
- Main HEPA in central AHU systems - Primary supply-air filtration in pharmaceutical cleanrooms - Large laboratory / operating-room HVACSelection Notes
- V-pack requires 290 mm installation depth. - First choice for high-flow, energy-efficient systems. - If depth is constrained, choose ATML (mini-pleats).Selection References
Before ordering, verify the efficiency grade, media type, and whether the operating environment fits your requirements.
