Duoline - Moduline - Topline

Summary

Product Identification

MODULINE™ Filter Housings

These are double or modular multibag units designed for larger flow rates. They are assembled from two or more standard SIDELINE (MSBF) or TOPLINE (MTBF) housings using standard elbows, manifolds, or T-Pipe modules. The MODULINE concept offers flexibility, allowing capacity to be increased by adding more modules. MODULINE housings are fabricated to customer specifications.

Specific models mentioned:

• MODULINE MTBF-02
• MODULINE MSBF-02

DUOLINE™ Filter Housings

Duplex units designed for continuous filtration processes. The DUOLINE bag filter system comprises two bag filter housings (either SIDELINE or TOPLINE) connected at the inlet and outlet by a butterfly or ball valve assembly. A center post handle assembly connects the valves to ensure synchronized change-over from one filter to the other. A quick turn of the handle diverts the flow, allowing the filtration process to run continuously during bag change-outs.

Specific model mentioned:

• DUOLINE DSBF

TOPLINE™ Dual Filter Housings

A compact 2-bag unit featuring a single cover-lid. The TOPLINE TBF-02 filter housing combines the advantages of the TOPLINE housing series with a compact 2-bag design. It includes eye-bolt closure and a standard adjustable leg assembly.

Specific model mentioned:

• TOPLINE TBF-02
