特点和好处
美孚航空HF系列航空液压油专为满足商用和军用飞机应用的苛刻要求而设计。这些高品质配方具有卓越性能的悠久历史，可在各种操作条件下提供长期无故障的服务。
产品功能和潜在优势包括：
特征 | 优势和潜在的好处 |
高粘度指数（VI） | 允许设备在很宽的温度范围内运行 |
优异的低温性能 | 在低环境条件下提供高性能操作 |
良好的化学和氧化稳定性 | 抵抗酸性成分，清漆和沉积物的形成 |
满足美国规范的“超级清洁”要求。MIL-PRF-5606（航空HF） | 确保泵，伺服阀和其他液压系统组件的可靠性能 |
应用
Mobil Aero HFA是一种优质液体，符合美国军用规格MIL-H-5606A（现已过时）的质量要求。它具有非常高的VI，适用于温度低至-54ºC（-65ºF）的温度。虽然美国军方不再使用这种优质液体，但它仍用于一些较旧的小型私人和商用飞机。它还可用于需要在极低温度下具有良好流动性的工业和商业设备，其中Mobil Aero HFA可在各种操作条件下提供长期无故障的服务。
Mobil Aero HF是一种优质液体，符合最新版美国军用规格MIL-PRF-5606的要求。它具有与Mobil Aero HFA非常相似的物理特性，并且还满足现代飞机液压系统所要求的“超洁净”要求。它主要用于军用飞机，但也用作小型私人和商用飞机的液压油，以及大型商用飞机起落架中的支撑液。它是北约编号H-515液体。

Mobil Aero HFA and HF are formulated for aircraft systems where use of hydrocarbon-based hydraulic fluids is required. They are low viscosity products, high VI (viscosity index) fluid with excellent low temperature properties, good anti-wear performance, and good chemical stability. Mobil Aero HFA and HF are composed of mineral base oil stock and contain shear-stable VI improvers.
Features and Benefits
Mobil Aero HF Series aviation hydraulic fluids are designed to meet the demanding requirements of commercial and military aircraft applications. These high quality formulations have a long history of excellent performance and provide long, trouble-free service over a wide range of operating conditions.
Product features and potential benefits include:
Features | Advantages and Potential Benefits |
High Viscosity Index (VI) | Allows equipment operation over a wide range of temperatures |
Excellent low temperature properties | Provides high performance operation in low ambient conditions |
Good chemical and oxidation stability | Resists the formation of acidic constituents, varnishes, and deposits |
Meets "super clean" requirements of U.S. Spec. MIL-PRF-5606 (Aero HF) | Ensures reliable performance of pumps, servo-valves and other hydraulic system components |
Applications
Mobil Aero HFA is a premium quality fluid that meets the quality requirements of the U.S. Military specification MIL-H-5606A (now obsolete). It has a very high VI and is suitable for use at temperatures down to -54 ºC (-65 ºF). While this quality fluid is no longer used by the U.S. Military, it is still used in some older, small private, and commercial aircraft. It is also used in industrial and commercial equipment requiring good fluidity at very low temperatures, where Mobil Aero HFA provides long, trouble-free service over a wide range of operating conditions.
Mobil Aero HF is a premium quality fluid that is approved against the most current version of U.S. Military specification MIL-PRF-5606. It has physical properties very similar to Mobil Aero HFA, and also meets "super-clean" requirements required by modern aircraft hydraulic systems. It is intended primarily for military aircraft, but it is also used as a hydraulic fluid for small private and commercial aircraft, and as a strut fluid in landing gear of large commercial aircraft. It is a NATO Code Number H-515 fluid.
