MSF-30P vs MSF-35P vs MSF-40P: Choosing the Right Frame Size
The MSF-P series spans five models — MSF-30P, MSF-30PA, MSF-35P, MSF-35PA, and MSF-40P — differentiated primarily by roll diameter, preheat drum sizing, and maximum design speed. The MSF-30P and MSF-30PA both top out at 300 m/min, with the 30PA featuring a larger lower corrugating roll (408mm vs 360mm) and substantially bigger preheat drums (552mm vs 400mm) for handling different paper weight and speed requirements. Moving up, the MSF-35P and MSF-35PA both reach 350 m/min, while the MSF-40P — the largest in the line — is rated for 400 m/min with a 520mm pressure roll and 552mm preheat drums on both medium and liner sides.

Selecting between these models comes down to matching frame size to actual production speed targets and paper handling requirements rather than defaulting to the largest available option — a corrugator line running moderate volumes may find the 300 m/min tier delivers the needed throughput without the capital cost of stepping up to the 40P's higher-speed specification.
