Description
ELGi AF SG - SMALL DP GAUGE
Differential Pressure Monitoring • Service Indicator
This differential pressure (DP) gauge is designed for use on compressed air filter housings to indicate element condition and help plan service before restriction impacts flow or pressure.
AF series DP gauges use a multi-color indicator band to make it easy to identify normal operation vs. service condition (per brochure).
Key Features
- Provides visual indication of filter element restriction to support proactive maintenance planning.
- Multi-color scale helps quickly identify normal, caution, and service ranges.
- Helps reduce unexpected pressure loss and energy waste from overloaded elements.
- Useful for managing element change intervals across multiple filtration points.

Benefits
- Helps keep compressed air systems operating efficiently by avoiding excessive pressure drop.
- Improves maintenance planning and reduces unplanned downtime.
- Supports consistent air delivery by flagging restriction early.
Installation & Application Notes
- Install per housing port and orientation requirements.
- Use gauge indication together with operating hours and air quality requirements to set replacement schedules.
- Reset/verify reading after element changes and leak checks.
- Verify compatibility using your ELGi equipment model/serial and service parts list before ordering.
Frequently Asked Questions
ELGi AF SG - SMALL DP GAUGE
▶️ Question: What does a DP gauge measure?
Answer: It indicates the pressure drop across the filter element, which increases as the element loads with contaminants.
▶️ Question: Why does pressure drop matter?
Answer: Higher restriction can reduce available flow and increase compressor energy consumption to maintain set pressure.
▶️ Question: When should I change the element?
Answer: Change when the gauge indicates the service range or per your planned maintenance interval.
▶️ Question: Does a DP gauge replace scheduled maintenance?
Answer: No—use it to validate condition and adjust intervals based on real operating contamination.
▶️ Question: Can I add this to an existing filter?
Answer: If the housing has a compatible gauge port, DP monitoring can usually be added—confirm fitment.
