7 The I-6xxC5 (TB), I-6xxMM, I-6xxA4. and I-6xxJF5 (TB) Series coalescers (“xx” denotes nominal cartridge length) incorporate multi-layered pleated media designed to provide superior dirt holding capacity in the field, combined with 0.4 micron efficiency. The I-6xxC5 (TB) replaces both Parker Velcon’s I-6xx85 (TB) and I-6xx87 (TB) cartridges. These cartridges are available in either threaded base or open-end configuration. CATEGORY FUELS Parker Velcon has tested and qualified a comprehensive range of products to meet the EI 1581 5th Edition Specification. For a complete listing of Parker Velcon’s current qualification tests, please visit our website at www.velcon. com/vessels. The categories for this specification are: CATEGORY C This category replaces the previous class A, B, &C of EI 1581 Third Edition. Parker Velcon’s new coalescer cartridges that meet Category C requirements are the I-6xxC5 Series (“xx” denotes nominal cartridge length). These cartridges have been developed to provide better water removal performance in surfactant-laden fuels, and improved filtration efficiency combined with longer life. Category ‘C’ cartridges can be used at any point in the fuel distribution system– from refineries to intoplane fueling. CATEGORY M This category covers military fuels, such as JP8 (similar to Jet A but containing anti-icing and other additives). Parker Velcon’s coalescer products for this category are the I-6xxMM Series cartridges. Category M qualified cartridges also qualify for Category C. CATEGORY M100 This category is for military fuels such as JP8+100. The ‘+100’ additive allows fuels to run at higher operating temperatures and reduces maintenance for high per-formance military jet engines. Parker Velcon’s coalescer cartridges for the M100 Category are the I-6xxA4 Series. ADDITIONAL INFORMATION The 5th Edition also allows operators to incorporate third stage filter cartridges with each category. Parker Velcon has currently qualified the CDF®-2xx Series monitor (water absorbing) cartridges for Category C and the FOW-2xx Series filter cartridges for Category M100. Another aspect of the EI 1581 5th Edition specification is the description of filter/separators as Type S (water and dirt), Type S-LW (for applications where low amounts of water are expected) and Type S-LD (for applications where low amounts of dirt are expected). Products qualified for Type S are also qualified for Types S-LD and Type S-LW.
