Product description
PVDF bag filter housing for chemically demanding liquid filtration
The PVDF bag filter housing is designed for industrial liquid filtration applications where chemical resistance, flexible configuration and reliable performance are required. This housing is used with standard liquid filter bags and is suitable for both coarse and fine filtration duties.
PVDF is selected when aggressive chemicals, elevated operating temperatures or corrosive environments are part of the process. The housing provides a practical and cost effective solution for applications where metal housings are not required or not suitable.
Filtration principle
The housing operates with replaceable filter bags installed inside the vessel. Process liquid enters the housing, flows through the filter bag and exits through the outlet connection, while particles are retained inside the bag.
This filtration concept allows:
-
high dirt holding capacity
-
stable flow conditions
-
simple and fast bag replacement
-
flexible filtration ratings depending on bag selection
Bag filtration is commonly used as pre filtration or as a main filtration step in industrial liquid processes.
PVDF material characteristics
PVDF offers strong resistance to a wide range of acids, bases and solvents and maintains mechanical stability at elevated temperatures compared to standard plastics.
Typical advantages of PVDF include:
-
high chemical resistance
-
higher allowable operating temperature
-
corrosion free operation
-
long service life in demanding environments
This makes PVDF bag filter housings suitable for chemically aggressive filtration applications.
Design and construction
The PVDF bag filter housing is designed for durability and ease of maintenance. Typical design features include:
-
housing body manufactured from PVDF
-
vertical, top loading bag design
-
removable internal basket for bag support
-
smooth internal surfaces for cleaning
-
configurable inlet and outlet positions
The housing allows quick access for bag replacement and cleaning without complex disassembly.
Bag sizes and configurations
The housing is compatible with standard liquid filter bag sizes:
-
size 1
-
size 2
-
size 3
-
size 4
Multi bag configurations are available for higher flow rates, allowing multiple filter bags to be installed within a single housing.
Operating conditions
Typical operating parameters include:
-
operating pressures suitable for industrial bag filtration
-
operating temperatures aligned with PVDF material limits
-
compatibility with a wide range of industrial liquids
Exact pressure and temperature limits depend on housing configuration, sealing material and process conditions and are defined during the configuration phase.
Compliance and safety
PVDF bag filter housings are designed in accordance with applicable pressure equipment standards. Depending on configuration and application, housings can be supplied with conformity documentation and CE marking.
