Product detailed description
Walter WK650-5.5/270P – Professional power with a huge tank
Walter WK650-5.5/270P represents the pinnacle of professional piston compressors. Thanks to the massive 270-liter air receiver, it provides an extraordinary reserve of compressed air, which is crucial for eliminating pressure fluctuations during demanding operations. This machine is designed for uncompromising deployment in industry, large car repair shops, and paint shops.
Investing in this model will bring you not only high performance but, above all, operational stability. The large volume of the pressure vessel means the motor switches on less frequently, which significantly saves mechanical components and extends the overall lifespan of the machine.
- ✅ Cast iron unit: Two-cylinder design with slow-running operation for maximum durability.
- ✅ Efficient cooling: Large radiator surfaces ensure low air outlet temperature.
- ✅ Mobility: Despite its robustness (145 kg), the machine is equipped with solid wheels for workshop handling.
- ✅ Cleaner operation: Improved filtration with a metal insert protects internal components from dirt.

Innovation and Machine Benefits
🔹 Reinforced components: Piston rings and valves are made of higher-grade steel, preventing pressure loss even under high heat.
🔹 Lower oil consumption: Thanks to more precise cylinder machining, minimal oil enters the compressed air.
🔹 Steel covers: Unlike cheap plastic covers, Walter uses metal filters and covers that withstand mechanical damage in a harsh workshop environment.
🔹 Stability: Wider wheel track and low center of gravity ensure the compressor doesn't "wander" on the floor during operation.
Ideal use in operation
- ✔ Tire services: Seamless power for impact wrenches and tire changers, even during simultaneous operation.
- ✔ Paint shops: The huge air reservoir (270 l) guarantees a stable, pulsation-free flow for a perfect finish.
- ✔ Sandblasting: Suitable for lighter sandblasting work requiring a continuous air supply.
- ✔ Carpentry workshops: Powering staplers, grinders, and blow guns without constant motor engagement.
