Choose automatic Brush (RAB) or automatic Vacuum (AVC) based on solids type, power/controls availability, and service preference.
Rotating Automatic Brush
Motorized rotating brush assembly automatically cleans the filter screen surface on demand. Sensor-triggered or timer-based operation for hands-free maintenance.
Automatic Vacuum Cleaning
Vacuum scanner sweeps the screen interior using differential pressure to create powerful suction. Rapid backflush cleaning cycles maintain flow under full pressure.
Quick reference guide to help you choose between RAB automatic brush and AVC automatic vacuum based on your application requirements.
| Technology | Solids Type | Typical Loading | Water Loss | Power/Controls | Best Fit |
|---|---|---|---|---|---|
RAB Automatic Brush | Fibrous, organic matter, algae | Moderate, steady | Minimal (continuous purge) | 120V/240V motor + ฮP sensor or timer | Surface water, canal, ponds with organic debris |
AVC Automatic Vacuum | Sand, silt, heavy granular | Heavy, variable | Very low (short backflush cycle) | 120V/240V motor + ฮP sensor or timer | High solids, fine mesh screens, critical uptime needs |
Select RAB when dealing with fibrous or organic solids from surface water sources. The mechanical brush action excels at removing algae and organic matter that can stick to screens. Ideal for applications where mechanical simplicity and steady solids loading are the norm.
Choose AVC for heavy or variable solids loading, especially sand, silt, and granular debris. The vacuum system handles fine mesh screens better and completes cleaning in 10-20 seconds with minimal water loss. Best for critical applications requiring maximum uptime and frequent cleaning cycles.
Sensors trigger cleaning automaticallyโno operator presence required.
Maintains optimal differential pressure and flow rates 24/7.
Perfect for unattended locations where manual cleaning is impractical.
Continuous operation without system shutdowns for manual cleaning.
Monitors pressure drop across the filter. When ฮP reaches the set threshold, cleaning initiates automatically. Adapts to changing water conditions and debris loads.
Set cleaning intervals based on known water quality patterns. Ideal for predictable solids loading or scheduled maintenance windows. Can be combined with ฮP sensor for hybrid control.
Both RAB and AVC require standard 120V or 240V AC power. Electric motor drives the brush rotation (RAB) or vacuum scanner (AVC). Minimal power consumption during cleaning cycles.
Integration Ready: Both systems can integrate with existing SCADA, PLC, or irrigation controllers. Remote monitoring and control capabilities available for advanced installations.
RAB and AVC cleaning modules mount directly to BIG Series inline filter bodies. Choose your cleaning technology independently from your filter size and screen type.
Our filtration specialist team will help you choose between RAB and AVC based on your water quality, solids type, and operational requirements.
