Prevost Female Coupler: High Flow Profile (ESI Series)
The Prevost ESI Series Female Coupler is a high-performance, single-stage safety coupling designed for the European High Flow (7.2 – 7.4mm) profile. Featuring Prevost’s world-renowned Prevo S1 technology, this coupler is engineered to eliminate the dangers of “hose whip” while providing an unrestricted path for maximum air volume.
The ESI series is the professional’s choice for permanent installations, such as wall-mounted air drops and manifold outlets, where safety, durability, and tool power are non-negotiable.
Key Performance Features
- Prevo S1 Safety Technology: This “one-push” safety system vents the downstream air pressure before releasing the plug. This prevents dangerous hose whip, protecting both the operator and surrounding equipment.
- High Flow Efficiency: The ESI profile is designed to deliver a massive volume of air, ensuring that air-hungry tools like large impact wrenches and spray guns never “starve” for power.
- Non-Marring Composite Body: Built from a high-tech, anti-static composite material, the coupler is lightweight and scratch-resistant. It is ideal for use around finished surfaces, such as in automotive paint shops or high-end furniture manufacturing.
- Airtight & Energy Efficient: Precision internal seals prevent costly air leaks, helping to reduce compressor wear and energy consumption.
- Ergonomic “Green Button” Design: The distinctive green push-button provides instant visual identification of the High Flow (Euro) profile and allows for effortless, one-handed tool changes.
