Product description
Sanitary filter bag housing for hygienic liquid filtration
The Sanitary Filter Bag Housing is designed for liquid filtration applications where hygiene, cleanability and process safety are essential. This housing uses replaceable filter bags and is suitable for a wide range of sanitary filtration duties, from coarse particle removal to finer clarification steps.
Sanitary bag filter housings are commonly applied in processes where product integrity must be protected and where cleaning and inspection are part of standard operating procedures.
Filtration principle
The housing operates with a single filter bag installed inside a supporting basket. Process liquid enters the housing, flows through the filter bag and exits through the outlet connection, while particles and contaminants are retained inside the bag.
This filtration principle provides:
-
high dirt holding capacity
-
stable and predictable flow behaviour
-
efficient removal of particulate contamination
-
flexible filtration performance depending on bag material and micron rating
Bag filtration is often used as pre filtration or as a main filtration step in hygienic processes.
Sanitary design
The Sanitary Filter Bag Housing is engineered according to hygienic design principles. Smooth internal surfaces, minimal dead zones and drainable geometry support effective cleaning and sanitation procedures.
Typical sanitary design features include:
-
smooth internal surfaces to minimise residue retention
-
drainable housing geometry
-
hygienic sealing systems
-
suitability for cleaning in place procedures
These design features support consistent hygiene levels in sensitive production environments.
Bag size compatibility
The Sanitary Filter Bag Housing is available for standard industrial filter bag sizes:
-
size 1
-
size 2
-
size 3
-
size 4
The selected bag size determines the filtration surface area and flow capacity. Bag size selection depends on process flow rate, contamination load and desired service interval.
Design and construction
The housing is manufactured from stainless steel suitable for sanitary applications and pressure rated operation. The vertical design allows safe handling of filter bags and easy access during maintenance.
Typical design features include:
-
vertical housing construction
-
removable internal support basket
-
secure lid closure system
-
vent and drain connections for safe operation
-
compact footprint for hygienic installations
Design details are selected during configuration to match process, cleaning and regulatory requirements.
Operating conditions
Typical operating characteristics include:
-
operating pressures suitable for sanitary liquid filtration
-
operating temperatures depending on housing material and seals
-
compatibility with a wide range of process liquids
Exact operating limits depend on housing size, configuration and process conditions.
Compliance and safety
Sanitary Filter Bag Housings are designed in accordance with applicable hygienic and industrial standards. Where required, housings can be supplied with pressure testing and conformity documentation.
