This 24 24 6 Koch Multi-Flo Series G filter (part number 112-603-003) delivers MERV 10 (45%) filtration in a rigid extended-surface microfiberglass design built for commercial and industrial HVAC.
Multi-Flo Series G uses progressively dense microfiberglass media in a galvanized steel frame with bonded plastic internal supports the rigid construction holds pleat geometry across variable airflow, making it a reliable choice for VAV systems where non-rigid filters can collapse under load.
When Multi-Flo Series G is specified
- Variable air volume (VAV) commercial HVAC rigid construction maintains performance across airflow swings
- Hospitals, clinics, and pharmaceutical facilities proven media reliability in critical IAQ applications
- Schools, universities, and office buildings long service life lowers total cost of ownership
- Manufacturing and industrial plants handles demanding atmospheric conditions and high dust loads

What MERV 10 captures
Captures fine dust, pollen, mold spores, pet dander, and most lint. A common upgrade for commercial buildings stepping up from basic pre-filtration without overloading existing air handlers.
Compatibility
Multi-Flo is designed to be interchangeable with most competitive rigid cell filters in the same nominal size and depth. The no header configuration drops into standard side-access and front-access housings without modification.
