INDUSTRIAL BP, BPHE, & BN SERIES

FILTER BAGS

BP, BPHE & BN Series Filter Bags feature a thermally-welded, unique design that results in consistent filtration efficiencies. They are designed to fit the BPHE-410 and BPHE-420 Housings. Higher productivity can be achieved with faster bag change-outs. The semi-rigid cylindrical design is easily crushed and incinerated.

FEATURES/BENEFITS

BP Series (Polypropylene Felt)

Filtration ratings from 1 to 200 microns to comply with any filtration requirement

Manufactured from felt due to its high solids loading capabilities versus similar mesh fabrics

A glazed finish, created by melting the outermost surface fibers, is used to produce a bond that reduces the possibility of migration

APPLICATIONS

Acids Alkalis Corrosive Fluids Micro-organisms Oils Organic Solvents

BPHE Series (High-Efficiency)

For those critical applications when high-efficiency combined with high dirt-holding capacity is required

Polypropylene materials are processed into microfibers with diameters of 1 to 10 microns or more, then converted into filter material

Microfiber media is covered with spunbonded polypropylene

BN Series (Strainer)

Woven monofilment materials are offered in nylon with micron ratings of

50 to 800 Efficiencies from 75 to 95% Materials are cleanable and reusable

CORRECTION CHART

The following chart is based on 1 centipoise. (CPS)

If your liquid is greater than 1 CPS:

1. Select your liquid’s viscosity

2. Determine your correction factor

EX: If your liquid’s viscosity is 100,

your correction factor is 8.3

3. Multiply the Bag Selection Guide (left) by your correction factor

WARNING: For drinking water applications, do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.

NOTE: This information is for general guidance. Users should test bag materials with media involved to determine compatibility.

CAUTION: Protect against freezing to prevent cracking of the filter and water leakage.
