Pleated Box Filter

Selection & Maintenance

1. Selection Factors:
2. • Application scenarios and cleanliness requirements: determine the required filtration efficiency level.
   • Processing air volume: Match the air volume required by the system.
   • Allowable resistance: Consider the fan capacity and energy consumption of the system.
   • Pollutant type: Is it particulate matter or gaseous pollutant?Size distribution?
   • Installation space and size: Ensure that the filter can be installed correctly.
   • Cost: Initial purchase cost and later replacement cost.
   • Environmental conditions: temperature, humidity, corrosion, etc.
3. Maintenance
4. • Regular inspection: Observe the ash accumulation of the filter and whether it is damaged.
   • Monitor resistance: Use a differential pressure gauge to monitor changes in resistance and replace it when the final resistance is reached.
   • Replace on time: replace according to the manufacturer's recommendations or actual resistance, otherwise it will affect air volume, increase energy consumption, reduce filtration effect and even secondary pollution.
   • Correct installation: ensure that the seal is good to prevent air flow from bypassing.
   • Safe disposal: For filters that deal with hazardous substances, they must be safely disposed of in accordance with regulations.

Common Issues & Considerations

1. Balance of efficiency and resistance: The higher the efficiency, the greater the resistance, which needs to be considered comprehensively.
2. Filter life: It's not that the more expensive the better. The key is to replace it on demand and on time.
3. Installation seal: Lax sealing will cause filtration failure.
4. Secondary pollution: Captured pollutants may be released after the filter is saturated.
5. Ozone generation: Some electrostatic or ionic technologies may produce ozone by-products.
