Learn about our low-pressure screw compressor series.
Our screw compressors can deliver oil-free air certified to Class 0, making them an ideal choice for pneumatic conveying applications—particularly in industries where product safety is paramount, such as cement, gypsum, and the food and beverage sectors.
In addition, our ZE/ZA series is ISO 22000 certified, ensuring that our products are suitable for the food and beverage industry.
The Advantages of Our Low-Pressure Screw Compressor Technology
Our low-pressure screw compressors deliver pressures of up to 4 bar(g) / 58 psi and flow rates of up to 10,800 m³/h / 6,350 cfm, offering distinct advantages and making them well-suited for a wide range of industrial applications, such as pneumatic conveying, truck unloading, and fluidization processes.
Reduce operating costs
Since energy costs account for a significant share of a compressor’s life-cycle expenses, you should prioritize the energy efficiency of your compressed-air system when evaluating your next investment. We are continually exploring innovative ways to enhance energy efficiency across production processes—whether by raising industry standards for low-pressure screw compressors, tailoring our solutions to suit each specific process, or offering additional options for recovering and reusing energy.
Long uptime – the core of innovative design
Our ZE/ZA positive‑displacement screw compressors are engineered with reliability in mind, helping you avoid unexpected downtime in your process. Reliability begins at the heart of our units: our components. A cooling jacket cools the bearings and the compressor housing, keeping the rotors at the lowest possible temperature and extending component life. In addition, the Elektronikon® Mk 5 precisely controls oil temperature, ensuring optimal oil lubrication and delivering superior performance.
Complete unit: Avoid unexpected installation costs
The whole is greater than the sum of its parts: By providing you with a fully configured unit that’s ready to go as soon as it arrives, you not only avoid installation costs but also ensure that all components work seamlessly together, delivering outstanding performance. For example, a water‑cooled aftercooler for cooling process air is an essential component, since hot air can compromise product quality. That’s why our units are equipped with an aftercooler—even in 500 kW VSD models that typically don’t include an integrated water‑cooled aftercooler on the market—so you don’t have to purchase and install one separately.
In addition, by integrating your low-pressure screw compressor system with dryers, air filters, and our service offerings, we can help you design an intelligent compressed-air solution that ensures all components of your compressed-air system are optimized for seamless, coordinated operation.
