Description
This 20″ × 20″ × 6″ Koch Multi-Flo Synthetic Rigid Cartridge filter (part number 112-662-008) is a MERV 12 rigid extended-surface cartridge engineered for commercial VAV air handlers and high-airflow industrial systems.
Why a rigid cartridge?
The Multi-Flo is purpose-built for variable air volume applications where airflow changes throughout the day. The metal-and-plastic frame construction holds pleat geometry regardless of whether the system is running at 50% or 100% airflow. Non-rigid filters balloon or collapse under changing airflow, creating bypass paths.
Design and construction
- Media: Extended-surface synthetic pleated media, supported by rigid internal separators.
- Frame: Rugged metal and plastic composite — stands up to vibration and variable airflow.
- Header configuration: Single Header.
- Efficiency rating: MERV 12 per ASHRAE 52.2.
What MERV 12 captures
Most allergens, mold spores, pet dander, smoke and auto-emission particles. MERV 12 sits between standard commercial (MERV 11) and high-efficiency (MERV 13) filtration — a good choice when you want more than MERV 11 but don’t need the pressure drop of MERV 13.
