Features

Highly Precise Filtration
Ideal cake filtration can be done with our original filtration face form. Not only chips and abrasive grains, but also gelatinized/ emulsified dirty oil, which inhibits stable grinding, can be eliminated.

Reduction of paper consumption
Paper consumption can be reduced greatly due to our original paper shape and filtration face form. Furthermore paper consumption can be less than 1/2 (Max. 1/6) by combining with super precision type magnetic separator (over the conventional models).

Stainless papaer transfer unit
Paper transfer unit is all-stainless, rust-proof, with almost no adhesion of ground particulates, and easy to clean.

Easy Maintenance
Easy maintenance due to simple structure.
With a transparent cover, the amount of paper inside is visible and it is easy to exchange papers.

 

Stable Transfer System
Enchanced durablity of paper transfer system and prevented paper tearing and catching due to our own method.
