ErtelAlsop Double O-Ring Pak - Stacked Disc Filter System
The ErtelAlsop Double O-Ring Pak System consists of our Pharma-Pak highly polished stainless steel double o-ring housing used in conjunction with our Bio-Pak double o-ring lenticular cartridge. Current flat gasket cartridge technology can present difficulties with sealing between gaskets, the misalignment of cartridges and the dynamic tension system necessary to seal cartridges. The simple quarter-turn lock and static core structure of the ErtelAlsop double o-ring filter element eliminates these concerns.
The sanitary Pharma-Pak housing helps ensure the integrity of your pharmaceutical or biotech application by providing a highly polished filter housing with sanitary fittings, vent connection and no internal threads. This model is provided in 316L stainless steel as standard and allows for easy cleaning after complete disassembly. The typical housing can hold up to four 12-inch or 16-inch diameter Pak cartridges in a vertical configuration. For additional integrity assurance, ErtelAlsop Bio-Pak double O-ring cartridges should be used within this housing.
The Bio-Pak is designed with no stainless steel parts. The center core is made of polypropylene and instead of flat gasket end caps, double o-ring plug-in style connectors are provided. This superior model provides the following advantages over the stainless steel strapped, flat gasket design:
- Positive sealing between cartridges and between the cartridge and the housing.
- The Bio-Pak center core provides a rigid structure, eliminating the need for a center post.
- No center post means less labor, as there is no need for lifting cartridges up and over a non-existent center post.
- Fewer material components in the assembly provide alternate disposal methods and reduce compatibility issues. The static structure of the polypropylene core does away with the moving seal required by flat gasket cartridges.
ErtelAlsop`s domed Pharma-Pak cartridge housing helps to ensure the integrity of your pharmaceutical or biotech depth filtration process by providing a highly polished filter housing with sanitary fittings, vent connection and no internal threads. The design is provided in 316L stainless steel as standard and allows for easy cleaning after complete disassembly. The typical housing can hold up to four 12-inch or 16-inch diameter Pak cartridges in a vertical configuration. For additional assurance of integrity, the ErtelAlsop Bio-Pak double O-ring cartridge may be used.
ErtelAlsop`s standard industrial grade Zeta-Pak filter housing is designed for everyday use in chemical applications where the high polish of the Pharma-Pak is not required. The filter is available in Carbon Steel, 304, 316, or 316L Stainless Steel, Polypropylene or Fiberglass Reinforced Polypropylene. Flow rates of up to 375 liters per minute per housing are feasible and housings can be mounted in series or parallel on a single framework to allow for higher flow rates and/or throughput. The filters are available with the standard gasketed head and external tightening handle or in our flanged head with internal tightening handle design with the option for ASME code.
The industrial design can also be supplied in ErtelAlsop`s unique horizontal design. The horizontal design makes it easy for one person to operate the filter from loading to unloading. Additionally, the flanged head design can be provided with a hinge and swing tightening bolts to further simplify the operation. As previously stated the horizontal design can be provided in various materials of construction and to ASME code.
