Description
EWS075-A Water Separator
The ELGi EWS075-A is a Water Separator accessory for compressed air systems. Proper filtration and separation help reduce particles, liquid water, and oil carryover that can damage tools, contaminate processes, and increase downstream maintenance.
Water separators are typically installed ahead of dryers and fine filtration to remove bulk liquid water and heavy droplets. This reduces the moisture load on the dryer and helps stabilize air quality in the distribution system.
Key Features
- Bulk moisture removal: Reduces liquid water carryover ahead of dryers and fine filtration.
- Reduces dryer workload: Less liquid water entering the dryer can improve overall system reliability.
- Protects distribution piping: Helps reduce corrosion and water accumulation in lines.
- Best practice placement: Commonly installed after aftercoolers and before dryers/filters.

Benefits
- Improves equipment life: Cleaner air helps reduce wear, sticking controls, and premature tool failure.
- Supports consistent air quality: Filtration helps control particles, liquid water, and oil carryover in the air line.
- Helps reduce unplanned downtime: Contaminant control reduces maintenance events caused by sludge, corrosion, or wet air.
- Supports efficient operation: Properly maintained filtration helps minimize unnecessary pressure drop.
Installation & Application Notes
- Place filtration and separation stages in the recommended order: bulk separation/pre‑filter → dryer → fine/coalescing → optional carbon (if vapor removal is needed).
- Size the filter/separator for your actual airflow and pressure; undersizing increases pressure drop and service frequency.
- Route condensate drains to an appropriate collection/management system and check drain operation during commissioning.
- Monitor differential pressure (where applicable) and replace elements when restriction increases to maintain performance.
Frequently Asked Questions
EWS075-A Water Separator
▶️ Question: Where should I install a water separator?
Answer: Install after the compressor aftercooler (or as close as practical) and before the dryer and fine filtration. This helps remove bulk liquid water early and reduces downstream moisture load.
▶️ Question: Does a water separator replace a refrigerated dryer?
Answer: No. A separator removes bulk liquid water and heavy droplets; a refrigerated dryer removes additional moisture by cooling the air to a controlled dew point.
▶️ Question: Do I still need filters after the separator?
Answer: Often yes. Filters are used to remove particles and oil aerosols to meet tighter air quality targets and protect sensitive equipment.
▶️ Question: How do I maintain it?
Answer: Verify condensate drainage and keep drain lines clear. Maintenance frequency depends on moisture load and operating hours.
▶️ Question: What signs indicate it’s undersized?
Answer: High carryover, frequent downstream wet air issues, or excessive pressure drop can indicate the separator or drain setup needs review.
