Bag Filter Housing Selection Guide

Review key selection factors for bag filter housings, including bag size, flow rate, pressure, material, connections, sealing, and maintenance access.

Overview

A bag filter housing holds the filter bag, supports the sealing area, directs liquid flow, and allows operators to replace bags when they load with solids. Choosing the right housing is just as important as choosing the filter bag. If the housing does not match the bag size, flow rate, pressure, material, or connection requirements, filtration performance and maintenance can suffer.

This guide explains what industrial buyers should review before requesting a bag filter housing quote.

What a Bag Filter Housing Does

In a typical bag filtration system, liquid enters the housing, passes through the filter bag, and exits after solids are retained. The housing must support the bag, handle operating pressure, maintain the seal, and allow safe access for maintenance.

The housing is not just a container. It affects flow distribution, pressure drop, sealing reliability, and ease of operation.

Single-Bag vs Multi-Bag Housing

Housing typeWhen it may be reviewed
Single-bag housingLower flow, compact installation, smaller batch systems, easier maintenance
Multi-bag housingHigher flow, larger process volume, longer service interval, industrial continuous operation

Final selection depends on liquid, flow rate, pressure, solids loading, operating schedule, and maintenance preference.

Bag Size and Basket Compatibility

The housing basket must match the filter bag size and ring style. Size #1 and Size #2 bags are common, but dimensions should always be confirmed with the housing supplier. Do not assume every bag will fit every housing.

If you already have a housing, send the model, photos, basket dimensions, and current bag information.

Material of Construction

Common housing material choices may include stainless steel, carbon steel, plastic, or lined options depending on the liquid and operating environment. Material selection should consider corrosion, temperature, pressure, cleaning method, and plant standards.

Do not select housing material by price only. A housing that is not compatible with the liquid can create maintenance and safety issues.

Flow, Pressure, and Connections

Important RFQ details include:

  • Required flow rate
  • Operating and design pressure
  • Liquid temperature
  • Connection size and type
  • Inlet/outlet orientation
  • Bag size and quantity
  • Seal material
  • Cover type and opening method
  • Installation space and maintenance access

RFQ Checklist

Need help reviewing a filtration specification? Send your size, material, micron rating, quantity, liquid/application, operating temperature, flow or pressure if known, and any photos or drawings. Go2Filter can review the details for quotation.

FAQ

Can I use any filter bag in any housing?

No. Bag size, ring style, basket design, and sealing method must match the housing.

What information is most important for a housing quote?

Flow rate, pressure, liquid, temperature, material requirement, connection size, bag size, and installation layout are the most important starting points.

Should I choose single-bag or multi-bag housing?

Single-bag housings are often reviewed for lower flow or compact systems. Multi-bag housings may be reviewed when higher flow or longer service interval is needed.
