Color coded disposable filter holder |
摘要 |
A disposable-filter holder comprises a shallow, box-shaped plastic housing of two pieces with intake and discharge stubs, a membrane-type filter being sandwiched between the two housing pieces which are joined together in a gas-tight and pressure-resistant manner. To reliably code the disposable-filter holder according to the filter characteristics, the disposable-filter holder comprises a colored coding plastic enveloping it in the outer radial zone. This color coding extends in at least one clearance in the first and/or in the second housing piece in geometrically locking manner and thereby does not project beyond the outer housing contour. The color coding only characterizes the disposable-filter holder and does not serve any sealing or locking function.
