Dual Fluid Fog Type Dust Suppression Systems Manufacturer
DSP Equipment is a manufacturer of Dual Fluid Fog Type Dust Suppression Systems for industries dealing with fine, fugitive and process-generated dust. The system uses a combination of water and compressed air to create a fine fog that can be directed toward dust-emission points.
The fine droplets are designed to interact with airborne dust particles, helping bring them down and limiting their movement into the surrounding work environment. Compared with conventional water sprinkling, dual-fluid fog technology can provide finer atomization with controlled water consumption, making it suitable for selected material-handling and processing applications. DSP Equipment develops application-specific systems for industrial plants across Kolkata, Bihar, Jharkhand, Odisha, Chhattisgarh and Assam.
How DSP Equipment’s Dual Fluid Fog System Controls Dust
The effectiveness of a dual-fluid system depends on delivering the fog close to the location where dust becomes airborne.
- Water Preparation
Water is supplied to the fog system through the designated water line or pumping arrangement.
- Compressed-Air Supply
Compressed air is supplied to the atomising nozzles to assist in breaking the water into fine droplets.
- Fine Fog Generation
The specially selected dual-fluid nozzles combine water and compressed air to generate a fine fog.
- Targeted Application
The nozzles are positioned around the dust-emission point so that the fog reaches the required zone.
- Dust Particle Interaction
Fine droplets come into contact with suspended dust particles, increasing their effective mass and encouraging them to settle.
- Controlled Operation
The system can be arranged in separate sections so that fogging is activated where and when the corresponding process equipment is operating.
What Is a Dual Fluid Fog Type Dust Suppression System?
A Dual Fluid Fog Dust Suppression System combines two operating media:
- Water
- Compressed air
These are supplied to specially design atomising nozzles. The interaction between air and water produces a fine mist or fog, which is discharged toward the dust-generating zone. The system is particularly useful where dust needs to be controlled without simply flooding the material with large quantities of water. Depending on the process, the fog arrangement can be installed at transfer points, crushers, screens, hoppers, feeders, discharge locations and other areas where airborne dust is generated.

Where Dual Fluid Fog Dust Suppression Works Best
Rather than treating an entire plant with water, dual-fluid fog systems are generally configured around specific dust-generation sources.
- Conveyor Transfer Points
Material falling from one conveyor to another can create a sudden release of fine dust. Fog nozzles can be positioned around the transfer zone.
- Crusher Feed & Discharge
Crushing operations can generate significant quantities of airborne particulate matter. A suitably designed fog arrangement can be directed toward the relevant emission points.
- Screening Plants
Fine particles released during screening can be addressed by installing fogging points around suitable sections of the screening arrangement.
- Hoppers and Feeders
Material dropping into or moving through hoppers and feeders can produce dust. Targeted fogging can be incorporated around the loading or discharge area.
- Wagon & Truck Loading Areas
For selected bulk-material loading operations, fogging can be used around the point where material enters or leaves transport equipment.
- Stockyard Material Handling
The system can be configured for selected material movement areas in stockyards where fine dust becomes airborne during handling.
Designed for Fine Dust at Material Transfer Locations
One of the important considerations in industrial dust control is where the dust actually becomes airborne. DSP Equipment focuses on locating fog nozzles as close as practical to the dust-generation source. The objective is to create an effective fog zone without unnecessarily increasing water application throughout the facility.
The final nozzle arrangement can depend on:
- Particle size
- Material characteristics
- Material drop height
- Conveyor capacity
- Belt speed
- Dust generation rate
- Air movement
- Available water pressure
- Compressed-air pressure
- Available installation space
- Required fog coverage
Why Dual Fluid Fog Instead of Conventional Water Spraying?
Conventional sprinkling systems generally apply comparatively larger water droplets over an area. A dual-fluid arrangement uses compressed air to atomise water into a much finer fog.
This distinction can be useful when:
- Fine airborne dust needs targeted treatment
- Excessive material wetting should be avoided
- The dust source is concentrated
- Water availability needs to be controlled
- Fogging needs to be directed into an enclosed transfer point
- Automatic zone control is required
The choice between plain-water sprinkling, dry fog, dual-fluid fog and other dust-control technologies should be based on the material, process, dust characteristics and permissible moisture addition.

Key Advantages of Dual Fluid Fog Dust Suppression
- Fine Atomisation
Compressed air assists in producing smaller water droplets than conventional coarse spraying arrangements.
- Lower Unnecessary Wetting
Targeted fog application can reduce excessive wetting where large-volume water spraying is undesirable.
- Suitable for Point-Source Dust
The system can be concentrated around specific transfer, loading, crushing or screening locations.
- Flexible Nozzle Positioning
Nozzles can be arranged according to the geometry of the equipment and the direction of material movement.
- Section-Wise Operation
Different dust-generating zones can be operated independently when appropriate controls are incorporated.
- Suitable for Existing Plants
A properly engineered arrangement can be incorporated into many existing material-handling facilities without replacing the complete process line.
