The milky-white circular core component in the center of the cover image is our company’s self-developed vane-type pneumatic motor, which operates at a standard drive air pressure of 6.2 bar and uses compressed air as its power source. The motor’s rotation drives an integrated hydraulic pressure‑boosting system, rapidly increasing the hydraulic fluid to an ultra‑high pressure of 130 MPa (as shown below), thereby delivering high‑pressure hydraulic oil to power various hydraulic torque tools, clamping fixtures, and high‑pressure testing equipment.
Shanghai Ellem vane-type pneumatic motor-driven explosion-proof axial fan, with a standard operating air pressure of 6.2 bar, power ranging from 0.66 to 7 kW, and no-load speed of 5,000–8,000 RPM; fully pneumatic with no electrical sparks, specifically designed for underground mine ventilation and air supply, ensuring airflow in tunnels, providing explosion-proof safety, and suitable for mining, tunneling, and chemical explosion-proof applications.
Shanghai Ellem pneumatic flip‑clamp reduction motor, custom‑designed for tooling fixtures, compatible with dual‑spindle CNC milling machines, specialized machining centers, and automatic loading/unloading clamp mechanisms for crescent‑shaped multi‑station fixtures. It employs pneumatic forward/reverse drive to achieve integrated operations of automatic workpiece clamping and post‑processing flip‑release. With an all‑in‑one design that combines reduction and flipping functions, a single unit can replace the conventional separate oil‑cylinder and pneumatic‑cylinder setups, simplifying the machine’s air and hydraulic circuitry. Powered by a standard 6.2 bar factory air supply, it features explosion‑proof safety and operates reliably in cutting‑oil, dusty, and humid environments.
