The Dropout DO300S is a revolutionary, "all-in-one" compressed air water separator and particle filter. Designed for point-of-use applications, it delivers 99.9999% liquid water removal without the need for expensive replacement internal filter elements.
Why Choose the Dropout DO300S?
Unlike traditional filters that rely on consumable media, the DO300S uses a unique multi-stage cyclonic technology. It is the ultimate insurance policy for your air-driven equipment, ensuring dry, clean air at the point of use.
- Maintenance Free: No replacement filters or cartridges required.
- High Efficiency: Removes liquid water and particles down to 1 micron.
- Consistent Performance: Low pressure drop ensures your tools get the power they need.
- Built to Last: Robust 304 Stainless Steel construction for industrial environments.
Technical Specifications
| Inlet/Outlet Connection | 1/2" BSPT |
| Flow Rate (Maximum) | 300 L/min (10.6 cfm) |
| Operating Pressure | 1 - 15 Bar (15 - 217 psi) |
| Particle Filtration | 1 Micron |
| Housing Material | 304 Stainless Steel |
| Water Removal Efficiency | 99.9999% |
Ideal Applications
The DO300S is specifically engineered for environments where air quality is critical to the final result:
- Automotive Refinishing: Prevent fish-eyes and moisture in spray paint.
- CNC Machining: Protect sensitive air bearings and valves.
- Abrasive Blasting: Prevent media clumping for a consistent finish.
- Plasma Cutting: Extend the life of your consumables.
Installation Tip
For maximum efficiency and "set-and-forget" operation, we highly recommend pairing the DO300S with a Dropout Auto Drain (DOAD128). This ensures that the separated water is automatically discharged, preventing manual drainage downtime.
GUARANTEED DRY AIR WHEN INSTALLED AT POINT OF USE.
