Description
Altec AIR AW-0280 A Series Water Separator
The Altec AIR AW-0280 is an A Series water separator designed to remove bulk liquid water from compressed air lines before it reaches downstream equipment. Using proven centrifugal separation in a compact housing, it helps reduce corrosion, sludge, and moisture-related issues across the air system.
With a 280 SCFM flow rating and 1-1/4" NPT connections, the AW-0280 is a practical choice for point-of-use protection or as a first-stage moisture separator ahead of filtration and drying.
Key Features
- Up to 99% bulk water removal: Centrifugal separation helps knock out liquid water and condensate at the source.
- Consistently low pressure drop: Typical pressure loss is 0.8 psi (55 mbar) at rated flow at rated flow.
- Easy condensate management: Automatic float drain standard on all AW models; externally accessible drain valve.
- Service-friendly housing: Designed for close-coupled installation and simplified maintenance access.
- Broad operating range: Rated up to 232 PSIG (16 barg) and 34°F (1°C) to 176°F (80°C).

Benefits
- Reduces moisture load: Removes bulk water before it can overwhelm downstream filters and air dryers.
- Helps protect air tools and processes: Less liquid water means fewer rust, washout, and contamination issues.
- Supports system efficiency: Low pressure drop helps preserve usable pressure and reduce energy waste.
- Simple upkeep: External drain access helps make routine service faster and more reliable.
Installation & Application Notes
- Install upstream of coalescing/particulate filtration and dryers to remove bulk water first.
- Size to your system’s actual airflow demand. Do not exceed 280 SCFM at 100 PSIG for best separation performance.
- Pipe condensate to an appropriate collection point and follow local requirements for condensate handling.
Frequently Asked Questions
Altec AIR AW-0280 A Series Water Separator
▶️ Question: What does the water separator do in a compressed air system?
Answer: It removes liquid water and large condensate droplets from the air stream using centrifugal separation, helping protect downstream filters, dryers, piping, and tools.
▶️ Question: How do I size this water separator?
Answer: Match the separator’s rated flow to your system demand. The AW-0280 is rated for 280 SCFM at 100 PSIG—avoid exceeding this flow if you want to maintain strong water separation performance.
▶️ Question: Where should I install it?
Answer: Install it upstream of coalescing filters, particulate filters, and air dryers—ideally after the aftercooler and receiver—so bulk water is removed before it reaches sensitive equipment.
▶️ Question: How is condensate removed?
Answer: AW models include an automatic float drain and an externally accessible drain valve, allowing condensate to be evacuated without disassembling the housing.
▶️ Question: What are the pressure and temperature limits?
Answer: It is rated for up to 232 PSIG (16 barg) with an operating range of 34°F (1°C) to 176°F (80°C).
▶️ Question: Do I still need a coalescing filter or dryer if I use a water separator?
Answer: Often, yes. A water separator removes bulk liquid water, but fine aerosols, oil vapor, and low dew point requirements typically require coalescing/particulate filtration and an air dryer depending on your target air quality.
