High-performance degas technology to enhance industrial ink jet printer performance
The UltiFuzor™ degas module from Pall is a compact and economical point-of-use hollow fiber contactor with a large membrane area. The UltiFuzor module is intended for use in a wide range of industrial ink jet printers to remove dissolved gasses, prevent bubble formation and assure printer performance.
The module features a lumenside or interior fiber ink flow path and unique tri-layer hollow fiber technology, enabling high degas efficiency performance. The module incorporates a black housing for UV sensitive inks and easy-to-use female luer lock compatible connections.
Lumenside Ink Flow Path
Passing the ink through the interior of the hollow fibers allows for sequential gas diffusion along the length of these fibers, from the inlet to the outlet of the module. This continuous ink degassing process is very effective for removing dissolved gases to very low levels. The extent of degassing can be controlled by regulating the vacuum level. Other factors, such as flow rate and temperature, will also affect the amount of dissolved gas removal.
The unique module design allows for a very large, effective membrane area due to high fiber packing density. As a result, the module can be used at relatively high flow rates and still achieve excellent dissolved gas levels.
Multi-Layer Hollow Fiber Membrane Technology
The UltiFuzor degas fiber has a thin, non-porous polyethylene membrane sandwiched between two protective, highly porous, polyethylene layers, as indicated in the photomicrograph to the left. The gas diffuses rapidly across the very thin middle layer, whereas its non-porous structure prevents even low surface tension inks from leaking into the vacuum line. The inner layer protects the fiber from being damaged by abrasive pigments and thus enhances on-stream life.
