Applications
- First-stage filtration in AHUs - Pre-stage for HEPA / ULPA systems - Outside-air intake pre-filtration - Plant-area air filtration in factoriesSelection Notes
- Light dust loading → DS-150 (57%). - General building HVAC → DS-300 (72%). - Heavy loading → DS-400 (76%) / DS-600 (82%). - Greater depth = slightly higher PD but higher dust-holding capacity.Selection References
Before ordering, verify the efficiency grade, media type, and whether the operating environment fits your requirements.
