low maintenance. Since 2021, we have delivered reliable pollution control solutions across
India.
Wet Scrubbers – Vertical & Horizontal
Wet scrubbers are air pollution control devices that use liquid (typically water or chemical
solution) to capture and remove contaminants from exhaust gas streams. They are highly
effective for soluble gases, fumes, and particulate matter. Our wet scrubbers are engineered
with high-efficiency packing media, mist eliminators, and recirculation systems for optimal
performance. The contaminated gas enters the scrubber, passes through a wetted packing bed
where pollutants are absorbed or captured, and clean gas exits through a mist eliminator to
remove entrained droplets.
Types
Vertical Wet Scrubber
Counter-current flow design where gas rises upward while liquid flows downward.Maximum gas-liquid contact time.
Best For
Laboratories, small to medium industries,
height-limited spaces
Horizontal Wet Scrubber
Cross-flow or co-current design with low profile. Easy access for
maintenance.
Best For
Height-restricted areas, large industrial applications

Dry Scrubbers – Media-Based Filtration
Dry scrubbers remove acidic or corrosive gases using a dry reaction media (activated carbon,
soda lime, or impregnated alumina). Unlike wet scrubbers, they produce no liquid waste, making
them ideal for applications where wastewater treatment is challenging or undesirable. The
contaminated gas passes through a packed bed of media where chemical adsorption,
absorption, or neutralization occurs. Dry scrubbers are particularly effective for low to moderate
gas volumes and for pollutants that are difficult to scrub with liquids.

Dust Collectors – Cyclone & Bag Filter Type
Our high-efficiency dust collection systems are designed for effective control of airborne dust
and particulate matter in industrial and laboratory environments. We offer both cyclone
separators for coarse dust and bag filter systems for fine particulate matter. Dual-stage systems
(cyclone + bag filter) are also available for maximum efficiency where high dust loads are
present.
Materials of Construction
PP+FRP
For chemical dust applications
MS+FRP
For general industrial use
Stainless Steel (SS 304)
For hygienic or corrosive applications
Type A
Cyclone Dust Collector
Uses centrifugal force to separate larger dust particles from the air stream. Dust-laden air enters
tangentially, creating a vortex that throws heavier particles against the wall where they fall into a
collection hopper. Clean air exits from the top. No filter media required – ideal for preliminary
filtration or for coarse dust applications.
Key Features
- No filter media – no replacement costs
- Low maintenance – no moving parts
- Handles high dust loads without clogging
- Suitable for high-temperature applications up to 400°C
- Collection efficiency: 70-90% for particles >10 microns
- Available in mild steel, stainless steel, or abrasion-resistant lining
Applications
- Woodworking and furniture manufacturing – sawdust and wood chips
- Metal grinding and polishing – metal shavings and dust
- Cement and construction materials – cement dust, sand, gravel
- Grain processing – grain dust and husks
- Recycling industry – paper, plastic, and metal fines
Type B
Bag Filter Dust Collector
Uses fabric filter bags to capture fine particulate matter with high efficiency. Dust-laden air
passes through filter bags where dust accumulates on the outer surface. A pulse-jet cleaning
system uses compressed air to periodically blow dust off the bags into the collection hopper.
Efficiency up to 99.9% for sub-micron particles.
Key Features
- Pulse-jet reverse air cleaning – automatic and continuous
- Easy bag replacement from clean side – no dust exposure
