Polypropylene Filter Bags for Data Center Water Treatment

Polypropylene filter bags are supplied in standard industry sizes, including #1, #2, #3, and #4 configurations. They can be manufactured with steel, stainless steel, or polypropylene rings as well as molded plastic flanges to ensure proper sealing and compatibility across standard commercial and industrial bag filter vessels.

By trapping rust, sediment, dirt, and suspended solids from chilled and condenser water loops, polypropylene bags prevent abrasive particulates from eroding piping, valves, and pump impellers. Keeping process water clean also prevents contaminant accumulation on heat exchanger surfaces, which maintains heat transfer efficiency and prevents unscheduled operational downtime.

Flow capacities vary by configuration, filter dimensions, and media porosity. Felt filter bags generally support flow rates ranging from 5 to 150 GPM per bag, while mesh bags can handle flow rates from 5 to 175 GPM per bag, allowing operators to design or scale filtration arrays to their exact loop circulation requirements.

Standard polypropylene felt bags operate in liquid temperatures up to 200°F and maximum operating pressures up to 100 psi, depending on the housing. Mesh bags and specialty constructions can handle system operating pressures up to 100 psi with allowable pressure differentials up to 35 psi before replacement is necessary.

Felt filter bags provide filtration efficiency up to 99% particle removal across micron ratings from 1 to 200 microns. Mesh filter bags accommodate coarse to fine surface filtration with ratings spanning from 1 to 1500 microns, allowing facilities to select the exact level of particle retention needed.

Yes, material traceability, dimensional inspection reports, and quality documentation are available for applicable configurations. Selected designs comply with FDA 21 CFR 177.1520 for food-contact polypropylene, NSF/ANSI/CAN 61 and 372 for drinking water safety, and ISO standards for filtration performance and element integrity evaluation.
