Building Air Filtration Systems

Enhancing Air Quality with Oberdorfer Pumps

Modern building air filtration systems—especially in industrial and commercial environments—often use electronic air filters or electrostatic precipitators to remove airborne contaminants. These filters require regular cleaning to maintain efficiency, and Oberdorfer gear pumps play a key role in automating this process.

How the System Works

  1. Contaminant Capture: Airborne particles such as dust, lint, pollen, smoke, and industrial pollutants are trapped on electronic filter screens.
  2. Cleaning Cycle Initiation: At fixed intervals, the system activates a cleaning cycle.
  3. Detergent Spray: An Oberdorfer gear pump delivers a controlled amount of detergent solution to spray nozzles that coat the filter screens.
  4. Flushing: After soaking, the filters are rinsed with clean water, also delivered by the pump or a secondary system.
  5. Drainage and Drying: The dirty water is drained, and the filters are dried before resuming operation.

Why Oberdorfer Gear Pumps Are Ideal for This Application

  1. Precise Flow Control
    • Gear pumps provide accurate, metered flow, ensuring the right amount of detergent is applied without waste.
  2. Durable Construction
    • Bronze housings and 303 stainless steel shafts resist corrosion from cleaning chemicals.
    • Carbon-graphite bearings offer long service life with minimal maintenance.
  3. Fixed-Cycle Operation
    • Pumps can be easily integrated into automated control systems for timed or sensor-triggered cleaning cycles.
  4. Compact and Quiet
    1. Suitable for installation in HVAC units, ceiling-mounted filtration systems, or standalone air purifiers.

Benefits of Using Oberdorfer Pumps in Air Filtration Systems

  • Improved Air Quality: Regular cleaning ensures filters operate at peak efficiency.
  • Healthier Work Environments: Removes allergens, bacteria, and pollutants from the air.
  • Reduced Maintenance: Automated cleaning reduces manual labor and downtime.
  • Energy Efficiency: Clean filters reduce airflow resistance, lowering HVAC energy consumption.

Typical Use Cases

  • Manufacturing Plants: Where airborne particles like fly ash, oil mist, or carbon black are common.
  • Commercial Buildings: Offices, malls, and airports with high foot traffic and air circulation needs.
  • Cleanrooms and Labs: Where air purity is critical for safety and compliance.
  • Tobacco and Textile Industries: Where lint, smoke, and fine dust are prevalent.
