High-temperature coalescing filter for oil separation HTNX - compressed air filtration with Nomex® up to 180 °C
The Donaldson Filter element FF 20/30 HTNX is a high-performance high temperature compressed air filter and coalescing filter for oil separation with UltraPleat® technology for operating temperatures up to 180 °C. This Donaldson filter element uses a temperature-resistant Nomex® drainage layer and is ideal for oil separation under extreme thermal loads - highly efficient compressed air treatment in accordance with ISO 8573-1 even at the highest temperatures.
Performance data & filtration properties
- Filtration type: High temperature coalescing filter for oil separation (HTNX) with UltraPleat® technology and Nomex® drainage layer.
- Nominal flow rate: 1,440 m³/h at 7 bar operating pressure.
- Temperature resistance: Compressed air filter can be used up to 180 °C thanks to temperature-resistant Nomex® fabric.
- Oil separation: 99 % oil separation efficiency (8 bar absolute, 10 mg/m³). Residual oil content ≤ 0.03 mg/m³ - oil-free compressed air at high temperature.
- Energy efficiency: Pleated filter element with minimal pressure loss and reduced energy costs.
- Validated quality: Tested in accordance with ISO 12500-1 and ISO 12500-3 - reliable compressed air quality in accordance with ISO 8573-1.
High-quality structure of the element
- UltraPleat® filter medium: Pleated 3D microfiber fleece made of borosilicate glass fibers for maximum oil separation at high temperatures.
- Nomex® drainage layer: Temperature-resistant high-performance fabric for reliable oil separation at extreme temperatures.
- Robust support structure: Stainless steel support sleeves (1.4301/304) reliably protect the filter element against pressure surges.
- High-quality materials: Aluminum end caps and stainless steel for optimum temperature and corrosion resistance.
- Reliable sealing: High-quality O-rings for a leak-free fit in the compressed air filter housing.
System compatibility
- Suitable for: This Donaldson filter element is designed as a replacement filter for Donaldson compressed air filter housings from the AG, SG, HD and P-EG series (size 20/30). Easy replacement of the coalescence filter in your compressed air system.
Typical areas of application
