Installation and Operating Guidelines
UltiFuzor™ Degas Module

5.0 General Comments

5.1 Removal of dissolved gases is dependent on a
number of factors. These factors can be
manipulated to achieve the desired degassing level.
• Flow rate: The slower the flow rate the better
the degas efficiency, since the gas has a longer
opportunity to come into contact with the fiber
wall.
• Temperature: The higher the temperature, the
less soluble is the gas and the greater is its
diffusion rate, leading to more efficient dissolved
gas removal.
• Vacuum level: The deeper the vacuum (that is
the lower the absolute pressure on the vacuum

USE IN POTENTIALLY EXPLOSIVE ATMOSPHERES
Installation and maintenance should be undertaken by a competent person. National and local codes of practice, environmental regulations and
health and safety directives must be adhered to and take precedence over any stated or implied practices within this document.
For fluids having low conductivity, there exists the possibility of generating static electricity during use with all-polymeric components. This could
potentially lead to a static electricity discharge, resulting in the ignition of a potentially explosive atmosphere, where such an atmosphere is
present. These Pall products are not suitable for use with such low conductivity fluids in an environment that includes flammable liquids or a
potentially explosive atmosphere.
Where flammable or reactive fluids are being processed through a Pall degas module, the user should ensure that spillages during filling, venting,
depressurizing, draining and module change-out operations are minimized, contained or directed to a safe area. In particular, the user should
ensure that flammable fluids are not exposed to surfaces at a temperature that may ignite the fluid, and that reactive fluids cannot contact
incompatible materials that may lead to reactions generating heat, flame or that are otherwise undesirable.
Pall degas modules do not generate heat, but during the processing of high temperature fluids, and process upset conditions, it will take on the
temperature of the fluid being processed. The user should ensure that this temperature is acceptable for the area in which the module is to be
operated, or that suitable protective measures are employed. When processing flammable fluids, the user should ensure that any air is fully
purged from within the assembly during filling and subsequent operation to prevent the formation of a potentially flammable or explosive vapor/air
mixture inside the equipment. This can be achieved through careful venting of the assembly or system.
To prevent damage or degradation which may result in leakage of fluids from this equipment, it is imperative that the end user check the suitability
of all materials of construction (including seals on the connections where appropriate) with the process fluid and conditions. The user should
ensure that the module is regularly inspected for damage and leaks, which should be promptly corrected, and that seals (where appropriate) are
renewed after every module change. Leakage of flammable or reactive fluids from this module, arising through incorrect installation or damage to
the equipment (including any seals), may generate a source of ignition if flammable fluids are exposed to a heated surface, or if reactive fluids
contact incompatible materials that may lead to reactions generating heat, flame or that are otherwise undesirable.
The user should ensure that the module is regularly inspected for damage and leaks, which should be promptly corrected, and that any seals are
renewed after every module change. The user should ensure that these products are protected from foreseeable mechanical damage that might
cause such leakage, including impact and abrasion.
Regular cleaning with an anti-static material is required to avoid the build-up of dust on the degas module.

side), the more effective it is at removing
dissolved gases. However, as noted above, it is
critical not to apply an excessive amount of
vacuum so as not to evaporate desirable ink
components.
5.2 The ink should be passed through a Pall filter,
having a removal rating of 5 µm or finer, so as not
to clog up the inlet to the UltiFuzor fine hollow
fiber membranes.
5.3 Periodically check for liquid in the vacuum line
and trap, and drain as required. If the ambient
temperature is significantly lower than the
operating temperature, the level of condensate in
the vacuum lines may increase, necessitating
more frequent draining.
