Filter Bag Size Chart - Find the Right Bag for Your Data Center System

Standard filter bag sizes include #1, #2, #3, and #4 configurations. In cooling and process water systems, these standard sizes are designed to fit compatible bag filter housings with steel, stainless steel, or polypropylene rings and plastic flanges. Each size accommodates varying dirt-holding capacities from 1 to 15 lbs per bag and supports specific flow rates depending on media type and micron rating.

Standard filter bags are available in polypropylene, polyester, and nylon media, along with specialty options. Construction includes felt media for depth filtration with sewn or welded seams, as well as monofilament or multifilament mesh for precise surface filtration. Material selection depends on operating conditions, with temperature limits reaching up to 200°F for felt and up to 450°F for specialized mesh configurations.

Flow capacity varies by bag size, media selection, and micron rating. Felt filter bags provide flow rates ranging between 5 and 150 GPM per bag. Mesh filter bags deliver flow rates between 5 and 175 GPM per bag. Operating within these parameters ensures effective particle retention while maintaining pressure differential within normal operating limits between 1 and 35 psi.

Micron ratings depend on media construction and application requirements. Felt filter bags provide depth filtration with micron ratings ranging from 1 to 200 microns. Mesh filter bags provide defined surface filtration across a broader range from 1 to 1500 microns. Both configurations achieve up to 99% particle removal efficiency under specified operating conditions, removing suspended solids, dirt, rust, and sediment.

Operating limits depend on filter construction and media type. Felt filter bags handle maximum operating temperatures up to 200°F, while mesh filter bags withstand temperatures up to 450°F. Both filter bag designs support maximum operating pressures up to 100 psi, depending on housing configuration, media selection, and overall system operating conditions.

Filter bags feature standard top styles including steel, stainless steel, and polypropylene rings, as well as plastic flanges. These ring styles ensure a secure seal within compatible filter housings to prevent bypass. Bags can also be configured with sewn or welded seams and optional handles or tabs for simplified installation, maintenance, and element replacement.
