Hytrex / Standard / Specialty Depth Cartridge Filters

high value general purpose depth cartridge filters

The Hytrex depth cartridge filter family is an exceptional value for general applications where long life, high purity, and low change-out frequency are required. The Hytrex family is 100% pure polypropylene depth filters (including adapters), with exceptional dirt-holding capacity. The true-graded density filter matrix (lower density at the surface of the filter with progressively higher density toward the center) captures particles throughout the entire filter depth. This translates to longer life and fewer change-outs compared to existing string-wound or other competitive depth filters. Hytrex and Purtrex brands are well-established world-wide with a long-standing customer base. 

Specialty filters Hypure AF and Pure HiTemp are quality products for high-temperature, high-pressure applications for solutions and solvents.

常见问题解答

常见问题

流体流动的方向是什么?

The direction of fluid flow in a depth filter cartridge is from the outside to the inside. This flow direction makes use of the greater outside diameter and surface area and allows for optimum use of the media for contaminant capture. 

what are the temperature limits and the differential pressure limits for depth filters? 

For non-cored (no additional plastic support core) the maximum recommended temperature is 160°F. As the temperature is increased the allowable differential pressure decreases. 

what are the recommended flow rates and how does fluid viscosity impact flow? 

The maximum recommended flow rates depend on the contamination of the fluid being filtered and the viscosity of the fluid. For "clean water" such as municipal water feed to an RO system the maximum flow rate is 5 gpm (18.9 lpm) per ten-inch length (TIE) of filter; e.g. a 40" filter will have 4 TIEs. 

As the contamination level increases, flow rates should be reduced to increase service life and more effectively utilize the depth filters’ media. For moderately contaminated fluids (10 ppm of solids) a flow rate of 2.0 gpm (7.6 lpm) /TIE is suggested. 

As fluid viscosity increases above 1 cps (i.e. the viscosity of water) the pressure drop will rise proportionately. Use the flow vs. pressure drop charts on the product fact sheet and multiply the value by the fluid viscosity to obtain the pressure drop. Size the filtration system to fall below the allowable maximum pressure drop.
