The ESCO 10390 22-Ton Professional Air Hydraulic Service Jack represents years of research, reengineering, and commitment to delivering a high-capacity lifting solution that meets the demanding needs of modern professional shops. With a massive 44,000 lb. lifting capacity, this jack is engineered to handle heavy-duty trucks, commercial vehicles, and the toughest service applications with ease. Unlike competitive jacks on the market, the Model 10390 features 100% air up and air down operation—eliminating the need for manual descending and dramatically improving workflow efficiency and operator safety.
Designed and manufactured to exceed expectations at a competitive market value, this service jack integrates cutting-edge pneumatic technology with robust construction. The 3-spring design provides superior control during both ascending and descending, ensuring smooth, stable operation while minimizing cylinder movement under load. The redesigned cylinder casing and air pneumatic system offer enhanced protection against debris intrusion, extending the life of critical internal components and reducing maintenance downtime.
Advanced 3-Spring Design for Superior Control
The heart of the ESCO 10390 is its innovative 3-spring cylinder design, a significant upgrade over traditional 2-spring configurations. This engineering enhancement delivers multiple performance advantages. The additional spring provides much more controlled ascending and descending of the cylinder, allowing technicians to make precise adjustments when positioning loads. This design also better stabilizes the cylinder, preventing unnecessary lateral movement while lifting vehicles—a critical safety feature when working under heavy equipment.
The 3-spring system makes descending of the jack quicker and more controlled compared to competitive models. Operators gain finer control over lowering speeds, reducing the risk of sudden drops and improving overall safety during service procedures. The enhanced stability also translates to smoother operation throughout the entire lift cycle.
Fully Pneumatic Air Ascend and Air Descend
One of the standout features of the Model 10390 is its redesigned air pneumatic system that enables the jack to ascend with air and descend with air. No more manual descending of the jack—a common pain point with traditional hydraulic service jacks. This 100% pneumatic operation is integrated directly into the jack's handle, with air ascend and air descend functions built into the handle for convenient, one-handed control.
The stronger, more durable handle design incorporates these pneumatic controls seamlessly while maintaining ergonomic comfort. Rubber-coated handle grips provide better handling and comfort when using the jack throughout long service days, reducing operator fatigue and improving grip even in oily or wet shop conditions. Operating at 116-174 PSI, the pneumatic system delivers consistent, reliable performance across a wide range of shop air supply configurations.
Redesigned for Durability and Debris Protection
The cylinder casing has been completely redesigned, along with the cylinder itself, to significantly decrease the ability for debris to penetrate into the cylinder, air motor, and internal mechanisms that could damage the jack. This enhanced sealing and protection extends component life and reduces the frequency of repairs and rebuilds—a critical consideration for shops that demand maximum uptime from their equipment.
Heavy-duty wheels are engineered for constant use and longevity of life. These robust casters handle the weight and movement demands of a 22-ton capacity jack day after day, ensuring smooth maneuverability across shop floors even when fully loaded. The combination of durable construction and thoughtful design refinements makes the ESCO 10390 a long-term investment that pays dividends in reliability and performance.
Versatile Lifting Range with Included Extensions
With a minimum height of 8.5 inches and a maximum height of 21.35 inches, the ESCO 10390 provides 12.85 inches of total lifting range (including the 3.35-inch extension screw). The jack includes a complete set of saddle extensions to adapt to various vehicle configurations:
0.75-inch (20mm) extension for low-profile contact points
2-inch (50mm) extension for mid-height applications
4-inch (100mm) extension for high-clearance vehicles and specialized lifting needs
This versatility, combined with the 48.8-inch handle length, gives technicians the reach and adaptability needed for a wide variety of heavy-duty service scenarios. Despite its substantial 22-ton capacity, the jack remains surprisingly maneuverable at just 66 lbs., making it easy to position and reposition as needed.
