Model 58N
The Model 58N housing is a rugged, economical housing with a 1/8” NPT drain. The transparent polycarbonate bowl and the nylon head, tie rod, and element retainer are resistant and non-absorbent to all components of the sample stream. The Balston 58N filter housing has much better corrosion resistance and is more economical than other filters used in this application.
The Balston Grade 404 Microfibre Filter Cartridges were developed specifically for use in sample lines to Gasoline Engine Analyzers. The filter cartridges are composed of borosilicate glass and polyolefin fibers. They have a 93% retention efficiency at 0.1 micron and offer a significantly higher solids holding capacity and lower pressure drop than conventional resin-bonded glass microfiber filter cartridges. The Balston Grade 404 filter cartridges are hydrophobic and drain water much more rapidly than all-glass fiber cartridges, greatly reducing the possibility of loss of NO2 and other water-soluble components from the gas sample.
When installed with inside-to-outside flow direction, the Grade 404 filter cartridges are efficient, fast-draining coalescing filters. When installed with outside-to-inside flow direction, the pure white surface of the filter tube permits quick visual estimation of the dirt loading on the filter cartridge.
In addition to the standard 100-12 size, Grade 404 Microfibre Filter Cartridges are available in sizes to fit all Vehicle Emission Analyzer filter housings.
