Key Features & Engineering Excellence
✅ Advanced Die-Cast Aluminum Housing
Precision Engineering: The YD430 AA 3-inch high-flow filter housing is manufactured from heavy-duty aluminum alloy using advanced die-casting technology.
Leak-Free Safety: Our expert mold design and rigorous process controls eliminate internal porosity (air holes), ensuring maximum structural integrity and pressure resistance.
✅ Maximum Durability & Corrosion Resistance
15-Year Service Life: Every housing undergoes premium electrophoretic treatment, ensuring up to 15 years of operational durability in harsh industrial environments.
Rigorous Testing: Certified via a 1000-hour neutral salt spray test (ISO 9227:2006).
100% Quality Inspected: Each unit undergoes 100% pressure leak testing and achieves a 5:1 burst pressure safety factor.
✅ Efficient Condensate Management
Automatic Drainage: Equipped with a reliable float ball auto-drain valve that instantly discharges accumulated liquids.
Uncompromised Efficiency: Continuous liquid removal ensures the coalescing filter maintains peak filtration efficiency and maximum flow capacity without pressure drops.
✅ Premium Air Purity with L430 AA Filter Element
Ultimate Protection: Safeguards downstream equipment and delicate instruments from solid particles, liquid water, oil aerosols, and vapors.
ISO 8573 Compliance: Removes contaminants down to 0.01 micron with a remaining oil content of ≤0.01 mg/m³ (at 21°C, 1 ppm w/w), fully meeting ISO 8573 air purity standards.
Cost-Efficient: Low differential pressure design significantly reduces energy consumption and total cost of ownership (TCO).
Partner with YunAir for High-Flow Success
The use of coalescing air filter is essential when high-quality compressed air is required. Our breath, as well as the compressed air we use in a wide variety of industrial applications, is not clean. Those latter contain particulates and aerosols, as well as oil vapors in the case of oil-injected compressors. The contaminants in compressed air are often microscopically small, but they can have a damaging and costly impact on sensitive equipment that uses compressed air.
YunAir filter element L430 AA is made from advanced fiberglass that effectively removes pollutant meeting the air quality requirements of all versions of ISO8573-1, reducing the energy consumption, total cost of ownership and adding to your satisfaction.
