The polyethylene element should be used where particulate contamination is a concern, and/or large slugs of liquid are present. The PEL20 (20 micron polyethylene) is a robust general purpose filter element. If greater filtration efficiency is required, and the main concern is liquid aerosol contamination, then we recommend using the 12-76-70CS coalescing element which is rated at 0.01 microns against 95% efficiency. While the grade 70CS provides greater efficiency, it actually has a lower pressure drop based upon its microfiber borosilicate construction.
- Supply Gas Filter: This filter will remove large amounts of moisture and particulate while still allowing a generous flow for Pilot Gas Applications. This housing is equipped with a 1/4” drain which allows the user to plug the drain or use an optional drain valve.
- Analyzer Filter: Point of Use filtration for critical application. The compact design/low internal volume allow a quick response time for sampling applications.
- Bottled Gas Filter: Rate for 5,000 PSIG this filter is suited for most bottled gas applications.
- NACE Approved: Complies with NACE MR-01-75.
By offering a higher pressure rating, a smaller footprint and a variety of elements with superior efficiencies the 122LB-PVF is an excellent upgrade to the Fisher 252 Series. Plus, the elements are completely interchangeable between the two assemblies. We also offer a 122LB-PVF with a 1/8”FNPT top head port which makes installation on some systems easier. This unit is designated as 122LBTP-PVF.
