An Air Scrubber Calculator is a practical tool designed to help determine the requirements for air purification systems. Whether you are managing HVAC systems or handling industrial pollution control, understanding the capacity and media consumption of air scrubbers is crucial. This straightforward guide will help you grasp how this calculator works and how to apply it to ensure your environments are safe and compliant with air quality standards.
Purpose and Functionality
The purpose of an Air Scrubber Calculator is to calculate the necessary capacity and media usage of an air scrubber based on several input variables. These include:
- Airflow Rate (Q): This is the volume of air needing purification, measured in cubic feet per minute (CFM) or cubic meters per hour (m³/h).
- Contaminant Concentration (C): The level of pollutants in the air, recorded in parts per million (ppm) or milligrams per cubic meter (mg/m³).
- Required Removal Efficiency (E): The percentage of pollutants that need to be removed to reach safe air quality levels, expressed as a percentage.
- Contact Time (T): The time the air needs to interact with the scrubber media, crucial for determining how effectively the air is purified.
Basic Calculations
To find the right air scrubber for your needs, you can follow these calculations:
Calculation of Air Scrubber Capacity
The formula to determine the required air scrubber capacity is: Scrubber Capacity=𝑄×(1−𝐸100)Scrubber Capacity=Q×(1−100E) Here, 𝑄Q represents the airflow rate, and 𝐸E stands for the required removal efficiency. This calculation estimates the airflow that must be treated to achieve the desired contaminant reduction.
Estimating Media or Chemical Usage
The consumption rate of the scrubber media or chemicals is calculated using: Media Consumption=𝑄×𝐶×𝑇Media Consumption=Q×C×T Where 𝑄Q is the airflow rate, 𝐶C the contaminant concentration, and 𝑇T the contact time.
Step-by-Step Example
Let's consider an industrial scenario:
- Airflow Rate: 1000 CFM
- Contaminant Concentration: 500 ppm
- Required Removal Efficiency: 90%
- Contact Time: 30 seconds
Calculate the Scrubber Capacity
Scrubber Capacity=1000×(1−90100)=100 CFMScrubber Capacity=1000×(1−10090)=100 CFM This calculation indicates that the scrubber must effectively treat 100 CFM of the total airflow to meet the removal requirements.
Estimate Media Consumption
Media Consumption=1000×500×30=15,000,000Media Consumption=1000×500×30=15,000,000 The units depend on the specific media or chemical used but this shows the total amount needed.

Conclusion
An Air Scrubber Calculator simplifies the process of designing and implementing air purification systems by providing quick and reliable estimates on scrubber capacity and media usage. It is an invaluable tool for ensuring that industrial and HVAC systems not only comply with air quality regulations but also maintain a safe environment for all occupants. This calculator aids in optimizing operational costs and efficiency, making it a vital component in the planning and maintenance of air quality management strategies.
