Airflow is important, but it does not describe the complete treatment duty. Two systems with the same airflow may need very different processes, materials and operating costs.
1. Describe the odor source
State the industry, process area and whether the air comes from tanks, channels, rooms, covered equipment or a production line. Explain whether collection ducting already exists and whether the system operates continuously or intermittently.
2. Provide gas data
Include normal and peak airflow, temperature, humidity, pressure, dust or mist loading and oxygen conditions where relevant. List the main pollutants—such as hydrogen sulfide, ammonia, acid gases or organic compounds—and provide inlet concentrations if measured.
3. Define the required result
Provide the applicable discharge standard, outlet concentration or odor requirement. State where the exhaust stack will be located and whether noise limits apply.
4. Explain site constraints
Share the available footprint and height, indoor or outdoor location, ambient temperature, corrosion conditions, utility availability, electrical standard and access for installation and maintenance. Drawings and photographs are valuable.
5. Request a complete scope
Ask suppliers to list the vessel, packing or media, pumps, dosing system, instruments, fan, duct connections, control panel, platform, stack, spare parts, documentation and packing. Ask them to state exclusions clearly.
6. Compare operating needs
Review chemical consumption, pressure drop, electrical load, water use, media replacement, cleaning, operator attention and expected maintenance—not only the purchase price.
A well-prepared RFQ lets suppliers propose a process against the same basis and helps the buyer identify meaningful technical differences.
