What is a commercial dust collector?
A dust collector draws dusty air from a machine or process through a filter or separator and gives out cleaner air. The dust falls into a hopper below. In a pulse-jet bag filter, the air passes through fabric bags, and a short burst of compressed air cleans each row of bags while the unit keeps running. A cartridge collector uses pleated filter elements to fit more filter area in less space. A cyclone spins the air so heavier dust drops out and is often placed before a bag filter. A wet scrubber uses liquid droplets to catch dust. In an air pollution control area, the State Pollution Control Board can approve the control equipment and chimney a factory must install.
This page covers commercial and industrial dust collectors for factories and plants; household and hobby workshop units are not covered.
How diipl verifies dust collector manufacturers
diipl checks every dust collector manufacturer before a buyer meets them. Every seller is GSTIN verified and capacity audited. IEC and the certifications your product and market need (ISO, CE, REACH, BIS) are confirmed before any meeting; Certificate of Origin and EIC inspection are arranged per shipment where required.
For dust collectors, the capacity audit also covers:
- welding and fabrication quality of casings, hoppers and tube sheets, with a leak test of the housing
- fit of bags or cartridges, cages and venturis, checked on an assembled unit
- a bench test of pulse valves and the cleaning timer or controller
- a test run at rated airflow with pressure readings taken across the filter
- material and coating records for the casing and for the filter media supplied
We match your requirement to a manufacturer that has passed these checks and arrange a direct meeting.
Types of dust collectors we cover
Indian dust collector manufacturers on the diipl bench build these commercial and industrial types.
| Type | Typical buyers |
|---|---|
| Pulse-jet bag filter (baghouse) | Cement, iron and steel, foundry, grain milling and coal cleaning plants. |
| Cartridge dust collector | Units that handle dusts such as welding fumes, pharmaceutical powders, grain and feed, and pigments. |
| Cyclone separator (pre-cleaner) | Plants with coarse, abrasive dust, as a first stage before a bag filter. |
| Wet scrubber (venturi type) | Chemical, mineral, wood, pulp and paper, metal and boiler plants that need high collection of fine dust. |
| Explosion-protected collector for combustible dust | Grain, flour, sugar and feed mills, and other plants with dust that can burn. |
Pulse-jet bag filter (baghouse)
Dusty air flows from the outside to the inside of felt bags held on wire cages. A short pulse of compressed air, 0.03 to 0.1 seconds long, knocks the dust off, and the unit keeps filtering during cleaning. Choose it for high dust loads and continuous plants. It needs a compressed air supply and dry gas. Typical new designs are rated for 99 to 99.9 percent collection.
Cartridge dust collector
Pleated filter cartridges replace bags, so the same housing holds more filter area. Cartridges are cleaned by pulses of air like bags and can be mounted upright or sideways. Media can be paper, spunbond plastic or nonwoven fabric. The adhesive that seals the media limits the gas temperature, so check the limit with the maker. Choose it for fine dust where floor space is tight.
Cyclone separator (pre-cleaner)
A cyclone uses spinning air to throw heavier dust to the wall, where it falls into a hopper. It generally has no moving parts and is used to collect particles larger than 10 micrometres. It is often used as a pre-cleaner to cut the dust load on a bag filter. Catching smaller particles needs more pressure drop and energy. Watch for wear, blockage and air leaks.
Wet scrubber (venturi type)
A venturi scrubber speeds the dusty air through a narrow throat and sprays liquid into it. Dust sticks to the droplets, which are then separated from the air. Collection runs from 70 to over 99 percent depending on the job, and higher efficiency needs more pressure drop and energy. It makes wet sludge and wastewater that need treatment. It can handle flammable and explosive dusts with little risk.
Explosion-protected collector for combustible dust
Flour, sugar, grain and similar dusts can explode, so the collector needs added protection. Guidance calls for open-bag filter units to be fully enclosed and fitted with explosion relief, and for relief vents to be ducted to open air and end in a safe, unoccupied area. Other measures include strong construction, isolation, segregation and suppression. Vents can have switches that shut the plant down when they open.
What to specify when buying a dust collector
A clear dust collector specification gets you comparable offers and a faster meeting. Share these points with diipl and we match them to the right manufacturer.
| What to specify | Why it matters |
|---|---|
| Airflow (air volume) to be handled | Airflow and the air-to-cloth ratio together set the filter area and the size of the unit. Standard factory-built baghouses are listed from under 0.10 to over 50 standard cubic metres per second. |
| Dust type and inlet dust load | A high dust load needs a larger baghouse so the dust cake does not get too heavy and raise pressure drop. Typical baghouse inlet loads are 1 to 23 grams per cubic metre. |
| Filter area and air-to-cloth ratio | Air-to-cloth ratio is airflow divided by filter area. The right value depends on dust load, dust character and cleaning method, so ask the maker to show the design value for your dust. |
| Filter media (felt bag or pleated cartridge) | Pulse-jet bags use felted fabric. Polyester, nylon and acrylic suit only low gas temperatures, about 95 to 150 degrees Celsius. Hotter gas needs fibreglass or other heat-stable fabric. |
| Gas temperature and moisture | Fabric filters handle gas up to about 260 degrees Celsius with suitable fabric. Keep the gas above its dew point, because moist or sticky dust can cake and plug the bags. |
| Cleaning method and compressed air supply | Pulse-jet units clean with a 0.03 to 0.1 second burst of air at 415 to 830 kilopascals gauge. Check that your plant air supply can meet this, and ask about the pulse valves and timer. |
| Pressure drop across the filter | Ask for the design pressure drop across the filter and how it is monitored. Typical baghouse values are 100 to 250 millimetres of water column. |
| Outlet dust level the maker will state | Well-designed baghouses have cut particulate emissions to under 0.05 grams per cubic metre. Ask for the outlet level the maker will state in the offer, and the test method used to prove it. |
| State Pollution Control Board consent and approved equipment | In an air pollution control area a factory needs the State Board's consent, and the Board can approve the control equipment and chimney it must install. Match the unit to your consent conditions. |
| Explosion protection for combustible dust | Flour, sugar, grain and similar dusts can explode. Ask about explosion relief vents ducted to open air and ending in a safe place, fully enclosed filter units, and switches that shut the plant down when a vent opens. |
| Dust discharge and disposal | Collected dust drops into a hopper below the filter. Plan how it is taken out, stored and disposed of, and how often the hopper must be emptied. |
| Scope: hoods, ducts, fan and stack | Fans and ductwork are auxiliary equipment to the filter itself. Confirm in writing whether hoods, ducts, fan, motor, stack and controls are in the quoted scope. |
| Materials, corrosion and coating | Moisture and corrosive gases are the main gas features that need design thought. Ask about casing material, coating, and where stainless steel is used. |
| Online emission monitoring | CPCB directions of February 2014 to State Boards covered 17 categories of highly polluting industries, including cement and iron and steel, for online emission monitoring that includes particulate matter. Ask your State Board whether your unit is covered. |

HSN code and ITC-HS code for dust collectors
Dust collectors are classified under ITC-HS 84213990 (other), within HS subheading 842139 (machinery; for filtering or purifying gases, other than intake air filters, catalytic converters or particulate filters for internal combustion engines). The 6-digit subheading is the same in every country that uses the Harmonized System; the 8-digit ITC-HS line is the one India files.
In India the GST HSN code and the export ITC-HS code come from the same nomenclature. A GST invoice needs only the first 4 or 6 digits, depending on your turnover; the export shipping bill carries the full 8-digit ITC-HS line. The classification is shown here; the applicable GST rate is not. Official source.

Dust Collector: frequently asked questions
Who makes dust collectors in India?
diipl does not publish manufacturer names. You tell diipl your requirement, and diipl matches a manufacturer that has passed GSTIN verification and a capacity audit. diipl also confirms the manufacturer's IEC and the certifications your market needs, then arranges a direct meeting between you and the manufacturer.
What should I specify when buying a commercial dust collector?
Give the airflow, dust type and dust load, gas temperature and moisture, and the outlet dust level you need. Ask for the filter area, air-to-cloth ratio, filter media, cleaning method and pressure drop. Say if the dust can burn or explode. Confirm what is in scope, such as hoods, ducts, fan and stack.
Which standards or certifications apply to dust collectors?
In India, a factory in an air pollution control area needs State Pollution Control Board consent under the Air Act of 1981, and the Board can approve the control equipment and chimney it must install. Industry-specific emission standards sit in Schedule I of the Environment (Protection) Rules, 1986. For export, CE marking applies in the European Union, and the ATEX Directive covers equipment for explosive atmospheres.
What is the HSN code for dust collectors?
Dust Collectors are classified under ITC-HS 84213990 (other), within HS subheading 842139. The export shipping bill carries this full 8-digit line; a GST invoice needs only its first 4 or 6 digits, depending on your turnover. Confirm the 8-digit line against your exact machine before you file.
Can Indian manufacturers export dust collectors?
Yes, if the unit meets the rules of the destination region. For the European Union, CE marking is placed after testing and a conformity assessment. Machinery placed on the EU market before 20 January 2027 follows the Machinery Directive, and the Machinery Regulation applies from that date. A collector for an explosive atmosphere may also come under the ATEX Directive. Agree Incoterms, spares and electrical supply early.
Which industries buy dust collectors?
Pulse-jet fabric filters are listed for use in boilers, iron and steel production, steel foundries, cement manufacturing, coal cleaning, stone quarrying and processing, asphalt manufacture and grain milling. In general, a fabric filter can be used in most processes where dust is generated and can be collected and ducted to one place.
I manufacture dust collectors. How do I find verified buyers?
diipl researches which buyer segments and regions need dust collectors, then runs outreach to reach them. diipl verifies each buyer's need, budget, authority and timeline before any introduction, and arranges a direct meeting. Your name and contact details are never published.
What is the difference between a bag filter and a cartridge dust collector?
A bag filter uses long cylindrical fabric bags held on wire cages. A cartridge collector uses pleated elements that pack more filter area into the same housing, and can be mounted upright or sideways. In pulse-jet units both are cleaned by pulses of compressed air. Cartridges can be effective on very fine dust where space is tight. The adhesive that seals the media limits the gas temperature, so check the limit with the maker.
How does a pulse-jet dust collector clean its bags, and what compressed air does it need?
Dusty air flows from outside to inside the felt bags, and the dust stays on the outer surface. A solenoid valve releases a 0.03 to 0.1 second burst of compressed air at 415 to 830 kilopascals gauge, row by row. The bag flexes and the dust drops into the hopper. The unit keeps running during cleaning, so you need a dependable compressed air supply.
Do I need explosion protection on a dust collector?
Possibly. First check whether your dust can burn. Flour, sugar, dried milk and whole grains such as wheat and maize can form explosive dust clouds. Guidance for these dusts is to totally enclose open-bag filter units and fit them with explosion relief, duct relief vents to open air ending in a safe, unoccupied area, and fit the vents with switches that shut the plant down. Isolation devices and suppression barriers can also be used. Ask the maker how your unit is protected.
What outlet dust level must a dust collector meet in India?
No single number applies to every plant. State Boards lay down emission standards under the Air Act and may set different standards for different industrial plants. Schedule I of the Environment (Protection) Rules, 1986 lists industry-specific standards, such as for cement plants. Check your consent conditions, then write the stated outlet level and the test method into the purchase order.
