Metaullics Cartidge Filter (MCF)
Applications, Specifications, Capabilities,
and Flow Rates
Filtration Efficiency
| Filtration efficiency depends on a number of factors. The superiority of the bonded particle Metaullics Cartridge Filter is based upon its pore structure and fineness, specific binder system, and great surface area provided by the cartridge configuration. Factors such as metal flow rate and inherent incoming metal cleanliness also affect filtration efficiency. Generally, the 20 and 24 grit filters are fully capable of removing virtually all inclusions down to 5 microns. |
Specifications
| MCF tubes are bundled into assemblies of 3 to 22 tubes. The assembly size is determined by metal flow rate, grit size of the filter media, throughput desired, and quality expectations. Fine grits, 10 - 12 - 14, permit higher flow rates and higher throughput for a given tube bundle assembly. Very fine grit sizes, 16 - 20 -24, provide the highest filtration efficiency levels, with larger tube assemblies necessary to accommodate the specific casting flow rate and throughput required. |
Filter Media Properties
The pore diameters of bonded particle MCF tube media are given below as a function of grit size.
Pore size distribution for the finest grits (20-24) show very good uniformity as shown below. Results were obtained by computed tomography analysis (CAT Scan).
Average pore size: 450 microns
Average pore size: 352 microns

Tube Configurations Available
Standard Tube Size Nominal: 3.93 in. OD x 2.36 in. ID x 34.37 in. length. Custom sizes can be developed and are available for other specific needs. Tube Bundles Metaullics Cartridge Filters are available in the following tube bundle assemblies. 3, 5, 7, 9, 11, 14, 18, 22 End plates are contructed from Metaullics Zx graphite or from nitride-bonded silicon carbide. |
Cartridge Filter Furnaces
Metaullics Systems builds holding furnaces housing the various size cartridge tube bundles. 30 - 100/KVA resistance heating is employed, with full SCR controls (power dependent on size, of course).
