String Wound Filter Cartridge
AJR Filtration proudly offers the EEF series of string wound filters, formerly sold under the Delta Pure name. EEF "Extremely Efficient Filtration" series string wound filters employ a 3-ply SMS polypropylene nonwoven final filter layer downstream of a wound pre-filter section. These filters remove a much higher percentage of fine particulate compared to traditional string wound filters – up to 99% of 0.5 micron particles.
Filter users with challenging fluids who need to remove particulates at or below 1 micron diameter, as well as those who want the economics and chemical compatibility of a string wound filter, have long relied on the EEF Series. Nominal removal ratings of 0.2, 0.5, 1, and 2 micron are available.
The EEF series of depth filters offer a choice of pre-filtration media and support cores. End fitting options allow the retrofitting of most filter housings. Precision winding geometry provides consistent and controlled pre-filtration to the downstream nonwoven final layer in order to achieve high dirt holding capacity. Cartridges are available in continuous lengths from 3” to 72” and diameters from 2" to 4.5”.
