Filter bag selection

Filter bag media, finish, and application conditions are selected together

A filter bag is not simply a matter of size. Temperature, moisture, acidic/alkaline gas, hydrolysis, oxidation, explosive dust, particle fineness, filtration velocity, and pulse-cleaning behavior are all evaluated together.

Hantech Filter is a filter bag manufacturer that selects materials and construction based on your process data and coordinates the supply of bags, cages, valves and air-handling equipment. Material test reports and certificates of origin are available on request.

Hantech Filter industrial filter bags and technical fabric options

Media selected from polyester to PTFE according to process conditions

For correct filter bag life in cement, lime, gypsum, mining, food, chemical, and power lines, temperature and chemical environment are assessed together.

Hantech Filter filter bag, cage and pulse-jet compatibility

Filter bag, cage, venturi, and pulse-jet compatibility

Cage diameter, wire count, venturi, pulse pressure, and differential pressure are inseparable parts of bag performance.

Dimension & connection

Snap-band, clamped, flanged, raw edge, ring, corded, or custom top connection.

Cleaning type

Seam and media selection based on pulse-jet, reverse-air, shaker, and horizontal/vertical mounting type.

Emission target

The choice between standard felt, microfiber, or ePTFE membrane is made based on the target outlet dust level.

Service Life

Wear, moisture, temperature fluctuation, and chemical load determine bag life.

Filter bag product types and temperature limits

When selecting filter bag media, continuous operating temperature, short-term peak temperature, and chemical resistance are evaluated together. The values below are a general selection reference based on Hantech's technical media classification and should be verified against the actual process temperature, moisture, oxygen, and gas composition.

Felt/scrim and fiber type	Continuous temperature	Peak Temperature	Hantech media code	Hydrolysis resistance	Acid resistance	Alkali resistance	Oxidation resistance
Polypropylene	95 °C	95 °C	PP	excellent	excellent	excellent	restricted
Polyamide	110 °C	115 °C	IN PA.	restricted	restricted	Good.	restricted
Polyacrylonitrile copolymer	115 °C	120 °C	a.c.	Good.	restricted	restricted	Good.

Polyacrylonitrile homopolymer	125 °C	140 °C	DT	Good.	Good.	restricted	Good.
Polyester	140 °C	150 °C	PE	restricted	restricted	restricted	Good.

* Peak values are for short-term excursions only and should not be used as the continuous design temperature. Bag selection should account for process temperature, dew point, moisture, acid/alkaline gas, and oxidation risk together.

Finishes and surface treatments

Temperature and chemical resistance comparison

Media	Heat	Acid/alkali	Hydrolysis	Oxidation	Optimal decision area
PE Polyester					General cement/silo dust
PP					Low temperature + chemical/moisture exposure
PPS					Acidic/moist hot flue gas
Aramid					Hot mineral/asphalt
P84					High temperature + fine dust
PTFE					Aggressive chemicals and critical emissions
Fiberglass					Very hot kiln gases

Site information required for the correct bag

Gas temperature: continuous / peak value
Dust type, particle size, abrasiveness, and moisture
Acid, alkali, SOx/NOx, solvent, or oil vapor
Filter area, air-to-cloth ratio, and current differential pressure
Cage size, venturi, pulse pressure, and cleaning cycle
Target emission value and the cause of the current bag failure

Check the selection limits together

No single property determines the right filter bag. Continuous and peak temperatures, gas chemistry, moisture, the emission target and cleaning conditions must be assessed together.

Material suitability is verified by comparing manufacturer specifications with actual process conditions.

Filter bag FAQ

Frequently Asked Questions About Filter Bags

What determines the price of a filter bag?

The main cost drivers are material and finish type (polyester, PPS, aramid, PTFE, ePTFE membrane, etc.), size and quantity, cage/top-fitting compatibility, any sample or certificate request, and lead time; the exact price is confirmed after your process data and technical quotation.

How many months or years does a filter bag last?

Service life depends on temperature fluctuation, moisture/hydrolysis risk, chemical load, pulse pressure and cleaning frequency, cage compatibility and maintenance routine. No fixed lifespan can be quoted; it is assessed together with your process conditions and failure history.

When is ePTFE membrane or antistatic finish needed?

ePTFE membrane suits very low emission targets, fine or sticky dust, and easy cake release; antistatic/conductive fibre is preferred in ATEX-risk environments (food, wood, coal, explosive dust).

Should I buy filter bags directly from a manufacturer?

Working with a filter bag manufacturer that coordinates material and construction selection with cage, valve and air-handling equipment compatibility provides faster, more consistent responses to requests for dimensions, finishes and technical certificates.
