Samgong SAM-3.5PE-300DR Air Motor – TESTED
The Samgong SAM‑3.5PE‑300DR is a resilient rotary vane air motor tested and verified for reliable low-speed output and robust torque performance. Designed to deliver a steady 300 RPM, this motor offers dependable power for precise applications such as valve actuation, indexing conveyors, small agitators, and remote tools in industrial and hazardous environments. The “DR” variant indicates a design optimized for durability, incorporating reinforced internals and premium sealing suitable for dust-prone or moisture-rich settings.
This air motor features a rugged, corrosion-resistant housing—typically cast aluminum or treated steel—paired with high-quality internal components engineered to withstand repeated starting loads, pressure spikes, and environmental stresses. The precision-machined vane and rotor system ensures smooth torque delivery with minimal pulsation, enabling precise control even under variable loads. Flange-style mounting dimensions and a compact footprint make it easy to integrate into new systems or replace existing pneumatic drives without extensive modifications.
Operators can easily regulate speed and torque via inlet air pressure and flow adjustments, offering versatile control for various task requirements. The reversible rotation feature adds further operational flexibility, enabling bi-directional use with simple air-line configuration changes. Free from electrical components, the SAM‑3.5PE‑300DR is inherently spark-free, making it ideal for use in explosive or combustible atmospheres—such as chemical plants, oil refineries, grain processing, and paint booths—where electrical motors can pose ignition risks.
Thorough testing confirms consistent RPM performance, torque output, seal integrity, and leak resistance, ensuring the unit is ready for immediate deployment. Maintenance demands are low due to easy-access bearings and vane assembly, and the motor's modular design allows for field inspection and servicing without full disassembly. In summary, the Samgong SAM‑3.5PE‑300DR Air Motor delivers safe, precise, and flexible pneumatic power for demanding industrial settings—combining durability, elegance, and user-friendly design in one compact package.
