A reverse pulse jet pleated filter dust collector filters dusty air through pleated filter elements and cleans them automatically with short bursts of compressed air while the unit keeps running. The pleats pack a large filter area into a compact body, and the pulses release the dust cake in about 0.1 seconds, so airflow stays steady with efficiency up to 97%+. Airo Shot Blast Equipments, Jodhpur, builds pulse jet pleated filter dust collectors from ₹1 lakh to ₹20 lakh.
What Is a Reverse Pulse Jet Pleated Filter Dust Collector?
A reverse pulse jet pleated filter dust collector (also called a pulse jet dust collector or pleated bag filter) is a dry dust collector with an automatic blasting machine system. Dust-laden air passes through pleated filter media, and the dust stays on the outer surface. A sequential timer then opens solenoid valves one row at a time. Each valve sends a short pulse of compressed air through a blowpipe into the filter, which flexes the media and knocks the dust cake off into the hopper.
Why Pleated Filters
Pleating folds the media into ridges, so the same body holds much more filter surface. More area means lower air speed through the filter, lower pressure drop, better capture of fine dust, and a longer filter life.
Why "Reverse" Pulse Jet
The cleaning air blows in the opposite direction to the dirty airflow, from the clean side to the dirty side, so it pushes the dust off the surface.
What It Does Not Do
Reverse pulse jet industrial dust collector collects dry dust and particles, not gases or vapours, and it is not suited to sticky, wet, or oily dust without special media.
How a Reverse Pulse Jet Dust Collector Works
Filtering
- Inlet: dusty air enters and slows down, and heavy particles fall straight into the hopper.
- Filtration: the air passes through the pleated filters, and fine dust builds a thin layer on the outer surface.
- Clean air out: air flows up inside the filters into the clean-air chamber, and the fan discharges it.
Cleaning
- A sequential timer (or pressure switch) triggers the cycle.
- A solenoid valve opens for about 0.1 seconds and releases a burst of compressed air through the blowpipe into the filter.
- The pulse expands the media, and a wave travels down the filter (in about 0.5 seconds), breaking the dust cake.
- The dust falls into the hopper.
- The pulses run row by row, so only a small part of the filter area is being cleaned at any moment, and the unit keeps filtering continuously.
Filter Media Options
| Media |
Typical use |
Notes |
| Polyester (non-woven) |
General dry dust, blasting, cement |
Good all-rounder |
| Polypropylene |
Damp or mildly chemical dust |
Resists moisture better |
| PTFE-coated |
Fine, sticky or slightly oily dust, pharma |
Dust stays on the surface, so release is easy |
| Antistatic media |
Powders and dust where static is a concern, such as powder coating and some chemicals |

Features and Benefits of a Pulse Jet Pleated Filter Dust Collector
- Automatic online cleaning: the unit keeps running while it cleans.
- Large filter area in a compact body from pleated media.
- Low air speed through the filters, which improves filtering.
- High efficiency on fine dust, up to 97%+.
- Low compressed-air use per cleaning cycle.
- Large dust hopper, so it needs emptying less often.
- Easy to operate, with a simple sequential timer.
- Easy filter change, with quick installation and removal.
- Media chosen to match your dust.
- Custom sizes from small units to large plant systems.
Pleated Pulse Jet vs Fabric Bag vs Cartridge vs Shaker Dust Collector
| Type |
Cleaning |
Continuous duty |
Filter area per unit |
Best for |
| Pleated pulse jet |
Compressed-air pulse, online |
Yes |
High |
Heavier dust loads, fine dust, continuous duty |
| Fabric bag pulse jet |
Compressed-air pulse, online |
Yes |
Medium |
General heavy-duty dust |
| Cartridge filter dust collector |
Compressed-air pulse, online |
Yes |
High |
Fine dust, smallest footprint |
| Motorised shaker |
Motor shaking, usually offline |

Shift-based work, low budget |
Rule of thumb: choose pleated pulse jet when you need more filter area in the same space and continuous running. Choose a plain fabric bag unit for coarse, heavy dust, and a shaker for light, intermittent jobs.
Choosing the Right Reverse Pulse Dust Collector
| Factor |
What to consider |
| Airflow (CFM) |
Total flow at all pick-up points, plus duct losses |
| Filter area and air-to-media ratio |
More area gives a lower velocity and longer filter life |
| Dust type |
Fine, dry dust suits it best. Sticky or oily dust needs special media or a pre-cleaner |
| Compressed air |
Pulse cleaning needs clean, dry air at the specified pressure. Oil or water in the line shortens filter life |
| Moisture and temperature |
Pick media rated for your conditions |
| Dust hazard |
Tell us if the dust is combustible so we can specify a safe design and antistatic media |
| Space and layout |
Pleats give more area per square metre |
