Fiber Rich” from Hollingsworth 81Vose, US is a filter media for use in industrial, oil, fuel and hydraulic filtration. It has a lower resin content than phenolic reenforced media, resulting in more elements per pound of media. Phenolic resin reenforced filtration media have been the norm for engine lubrication applications since they provide durability in hot oil and offer acceptable processing characteristics. The use of standard phenolic resins, however, requires long curing times as well as considerable air pollution control investments. FiberRich has been developed as an alternative to phenolii and offers lower free formaldehyde content and hence a cleaner plant environment. It offers comparable elevated temperature stiffness to standard phenolics even at the lower resin content for Fibre Rich. Lower curing requirements mean reduced energy costs; lower free phenol results in less smoke, lower stack emissions and less maintenance time for oven cleaning; and no O!WA content labelling is required since levels of free formaldehyde are well below 1000ppm.

Ceramic Crossflow Microfiltration Membranes from

lFalrey lnduetrlal Ceramics Ltd, UK use advanced turbu-

lence inducing star-shaped flow channeh for mic7ofiltration applications where high temperature, wide pH range, steam sterilisability, abrasion resistance, rigidity to assist backwashing, and long life are requirements. The turbulence inducing flow channels utilise low flow for high velocities, and are therefore more energy efficient. Low flow reduces pump size, pipe sizing and process equipment sizing. In place cleaning at hiih temperatures is also possible. INTREPIDm Filtration Media from Kimberley-Clark Corporation, USA is targeted for use in ASHRAE heating, ventilating and air conditioning filters for commer15 cial, industrial and residential applications. Intrepid Filtration Media is made of continuous polyolefin fibres which will not shed. The fibres are hydrophobic, so will not absorb moisture which can lead to microbial growth. The fibres are thermally bonded together without any chemical binders which could promote microbial growth or generate volatile organic compound (VOC) emissions. The media can be internally pigmented with various colours to differentiate between media or highlight the gradient structure and assist with correct filter manufacture. The media allows ASHRAE filter manufacturers to make pleat and bag filters with higher efficiencies, lower pressure drops and higher dust holding capacities than comparably priced media.

Cartridge Filters

16

The MFP-2000 from Palas GmbH, Germany is designed for the measurement of the fractional efficiency of filter media for special standards such as EN 1822, SAEJ 1669, ASHRAE 5, 52 P and DIN 71460. A novel aspect is the modular co+tiruction of this. filter test rig containing aerosol generators, a discharge system and a particle measurement device. Due to the possibility of using different generators in one test rig, the user can carry out tests according to diirent standards with only one rig. In addition the single components of the test rig can also be used in other test systems. Tests can be carried out easily, qulckly, reproducibly and very exactly using very lii quantities of test dust.
