Koch Multi-Flo & Multi-Sak Bag Filters | Series S & G

Koch Multi-Sak and Multi-Flo are the extended-surface pocket filter lines for general commercial and industrial air handler service. Multi-Sak 45/65/85/95 Series S covers MERV 9 through MERV 14 across standard commercial AHU applications. Multi-Sak Series G uses upgraded media for higher-efficiency requirements. Multi-Flo Series S and Series G handle higher-velocity AHUs where standard pocket filters can't maintain efficiency. Bag construction packs extended media area into a compact face dimension, dramatically extending service intervals over equivalent pleated panels and lowering total fan energy use across the filter's service life.
