01
What Type of Pollutant Do You Need to Treat?
The first and most important information is the type of pollutant generated by your production process.
Different pollutants require different treatment technologies.
For example:
- Metal dust → Dust Collector
- Welding fumes → Welding Fume Extractor
- Grinding dust → Grinding Table + Dust Collector
- VOCs → Activated Carbon Adsorption / RCO / RTO
- Acidic or alkaline gases → Wet Scrubber / Spray Tower
- Odorous gases → Activated Carbon or other odor treatment systems
If possible, provide the chemical name, dust type, VOC composition, or other available information about the exhaust gas.
02
What Is the Required Airflow?
Airflow is one of the key parameters for equipment selection.
The required airflow directly affects the size of the dust collector, scrubber, VOC treatment system, fan, ductwork, and other components.
Airflow may be provided in:
- m³/h
- Nm³/h
- CFM
- m³/min
If you already have an existing ventilation or exhaust system, you can provide the current airflow data.
If the airflow is not known, don't worry.
A professional supplier can estimate the required airflow based on the number of collection points, production equipment, workshop layout, and process conditions.
03
What Is the Pollutant Concentration?
Knowing the pollutant concentration is especially important for VOC treatment and industrial dust collection systems.
For example, VOC concentration may be expressed as:
- mg/m³
- ppm
- % by volume
Dust concentration may also be provided in mg/m³ or other available units.
If you have an exhaust gas testing report, laboratory analysis, or environmental assessment report, sharing this information can significantly improve the accuracy of equipment selection.
04
What Is the Exhaust Gas Temperature?
The operating temperature of the exhaust gas is another important factor.
Different environmental treatment systems have different temperature requirements.
For example, high-temperature exhaust may require special materials, cooling equipment, heat exchangers, or other protective components.
For systems such as RTO and RCO, temperature is also an important parameter when evaluating the overall process design.
When requesting a quotation, provide:
Normal operating temperature + Maximum temperature
if this information is available.
05
How Many Pollution Sources Are There?
The number and location of pollution sources are particularly important for dust collection projects.
For example, a factory may have:
- 5 grinding machines
- 3 welding stations
- 2 cutting machines
- 4 polishing stations
In this case, the system may require multiple collection points connected to a centralized dust collector.
Providing the number of machines and collection points helps engineers estimate the total airflow and design the ductwork.
06
What Is Your Production Process?
A simple description of the production process can provide valuable information.
For example:
Metal Processing → Cutting → Grinding → Polishing → Packaging
or:
Plastic Production → Mixing → Heating → Extrusion → Cooling
or:
Coating Process → Mixing → Spraying → Drying → Exhaust
Different processes produce different pollutants.
Understanding the complete process helps engineers determine where pollutants are generated and what treatment technology is most suitable.
07
What Are Your Local Emission Requirements?
Environmental regulations vary from country to country and from region to region.
If you have a required emission limit, environmental permit, or local standard, please provide it when requesting a quotation.
For example, you may need to meet a specific concentration limit for:
- Dust
- VOCs
- SO₂
- NOx
- Acid gases
- Odorous compounds
Knowing the required outlet emission level helps determine the appropriate treatment process and equipment configuration.
08
How Much Installation Space Is Available?
Even when the treatment technology has been determined, the available installation space can affect the final equipment design.
If possible, provide:
- Available length
- Available width
- Available height
- Equipment installation location
- Distance between equipment and exhaust points
- Indoor or outdoor installation
Photos or drawings of the installation area are also very helpful.
09
How Many Hours Will the System Operate?
Operating conditions are also important when selecting environmental equipment.
Please provide information such as:
- Hours per day
- Days per week
- Continuous or intermittent operation
- Seasonal production changes
- Peak production conditions
For example:
8 hours/day × 6 days/week
or:
24-hour continuous operation
This information can affect equipment selection, energy consumption, maintenance requirements, and system configuration.
10
What Is the Best Information to Send to the Supplier?
| Information | Example |
|---|---|
| Industry | Metal Processing |
| Process | Grinding / Welding |
| Pollutant | Metal Dust |
| Airflow | 20,000 m³/h |
| Dust Concentration | 500 mg/m³ |
| Temperature | 40°C |
| Operating Time | 8 h/day |
| Number of Collection Points | 10 |
| Emission Requirement | Local Standard |
| Installation | Indoor |
| Available Space | 6 × 4 × 3 m |
What If You Don't Have All the Information?
Don't worry if you do not have all the technical data.
Many customers do not have detailed airflow or pollutant concentration information when they first contact an environmental equipment manufacturer.
You can start with the information you already have, such as:
Factory type + Production process + Pollutant type + Number of machines + Photos + Available installation space
Photos, videos, process descriptions, existing equipment drawings, and environmental testing reports can also help engineers understand your application.
The more information you provide, the easier it is to develop a suitable solution.
