Baslton Sample Filter Cartridge and Housing Selection

Filter Cartridge Description

Parker Hannifin filter division BALSTON supplies filter cartridges in three different designs: LP Cartridges, Sintered Stainless Steel Cartridges, and Microfibre Filter Cartridges (X, H, or Q-type). See Table 1 for descriptions:

Table 1 Filter Cartridge Description

LP Cartridges:

Designed to filter liquids with high solids contents. Have an integral prefilter and an external support structure (flow direction is inside-to-outside).

X-Type Cartridges:

Used for solids and relatively large amounts of suspended liquids in gases. Provide excellent chemical resistance, temperature resistance to 300°F(150°C), and good mechanical handling properties. These cartridges have thick walls for improved coalescing efficiency. Should be used whenever permitted by housing internal volume. Fluorocarbon Resin Binder.

Q-Type Cartridges: Coalescing

Used for solids and trace amounts of liquids in gases. Also ideal for liquid service and removal of particulates. Similar to X-Type cartridges in chemical and temperature resistance. Fluorocarbon Resin Binder.

S-Type Cartridges:

Used for solids and trace amounts of liquids in gases. Also ideal for liquid service and removal of particulates. Improved chemical and temperature resistance properties over Q-Type. PTFE Resin Binder. Max temp 500°F.

H-Type Cartridges: Particulate

Recommended for oxygen service or when X-Type or Q-Type are unsuitable. H-Type cartridges have temperature resistance to 1000°F (538°C) in dry gas, 100°F (38°C) in liquid . Quartz construction,

M Type Sintered Stainless Steel Cartridges: Particulate

Designed for applications having heavy loading of solid contaminants.These cartridges are also suitable for removing heavy, viscous liquids from gases and as prefilters to high efficiency final filters. Constructed of 316 stainless steel with molded viton end seals.

CI Cartridges:Vapor Adsorption

Used to remove trace quantities of oil vapor. Activated carbon sandwiched between two layers of microfiber filter media absorbs oil vapor. Must be prefiltered with Grade DX and Grade BX. Max. operating 180°F/82°C.

How To Select The Filter Cartridge

1. When selecting a cartridge, do not overspecify. Select the coarsest grade which will adequately protect the instrument. Coarser grade filters provide lower pressure drop and longer life than finer grades.

2. When selecting X, Q, or H type cartridges, a D or B positioned before the cartridge type will determine the retention efficiency (see chart to the left). For LP and Sintered Stainless Steel Cartridges, the numerical Grade value indicates retention efficiency (see Table 2).

3. Refer to the chemical compatibility chart on page 38 to confirm compatibility of the filter cartridge material with the sample composition.

How To Select The Filter Housing

1. Select a filter housing in the material appropriate for your application. Please refer to the Application Index on Sample Filter Funcations Page , and the appropriate data sheet.

2. Select a filter housing with a port size equal to the line size where the filter is to be located. If the line size at the filter has not yet been selected, determine the gas flow rate and pressure at the point where the filter will be located, and refer to the appropriate flow chart on pages Sample Filter Funcations Page of this bulletin. Flow rates for liquids are located on Sample Filter Funcations Page and flow rates for air and gas sample filters are located on Sample Filter Funcations Page .
