The Straight Line Filter originated from a need for a practical horizontal vacuum filter with separable filter medium which would overcome the mechanical and physical problems (such as blinding and discharge difficulties) inherent in horizontal pan type filters.

Since it's introduction by Straight Line Filter, Inc., continuous belt filtration has become the method of choice in many industries.

Customers of Straight Line Filters, Inc. maintain direct contact with our management assuring individual and professional service from inquiry through testing, purchase, construction, startup and in plant operation.

Because Laboratory vacuum filtration is commonly done with Buchner Funnels, Straight Line Filters, Inc. has adopted the concept of the Buchner Funnel in its design for continuous filtration. This concept has been so successfully adopted that the correlation between Buchner Laboratory Tests and Straight Line Filter operations allows us to perform sizing and cycle studies with a modified Buchner Funnel. Many customers use this tool to continuously monitor their filtration process.
