Rotary screw compressors with 1:1 direct drive on a base frame

Rotary screw compressors with 1:1 direct drive on a base frame

Rotary screw compressors with 1:1 direct drive mounted on a base frame are designed for stationary compressed air systems with separately planned peripherals. In this category, you will find the fixed-speed D Series ranging from 11 to 90 kW.

Depending on the power rating, operating pressures of 8 or 10 bar and flow rates ranging from approximately 1.3 to 15.4 m³/min are available. The direct 1:1 power transmission sets this series apart technically from the belt-driven models. Since the design does not include an air receiver or refrigerated air dryer, storage, drying, and filtration can be configured separately to suit the existing or planned compressed air network.

D Series with 1:1 direct drive on a base frame

Rotary screw compressors with 1:1 direct drive mounted on a base frame constitute the fixed-speed variant within the direct-drive product group. The current D-Series lineup covers ten power ratings ranging from 11 to 90 kW.

From 1.3 to 15.4 m³/min

At 11 kW, the flow rates are 1.3 and 1.5 m³/min, respectively. The series ranges from 15, 18.5, 22, 30, 37, 45, 55, and 75 kW up to the 90-kW model with 13.4 or 15.4 m³/min. The models are designed for 8 or 10 bar.

Fixed-term for predictable demand

The D Series does not feature variable speed control. It is therefore particularly well-suited for applications where compressed air demand remains relatively constant and predictable over the operating period. For applications with highly variable load profiles, the DV Series is available as a separate category within the direct-drive product family.

Base frame without integrated storage

The models listed here are offered on a base frame. Air receivers, refrigerated air dryers, and filter stages must therefore be planned separately. This is advantageous if suitable peripheral equipment is already available or if the compressed-air treatment needs to be specifically adapted to the process.

Dimensioning the D Series

✅ Determine the required continuous flow rate

✅ Choose 8 or 10 bar depending on the application

✅ Take line losses into account

✅ Calculate storage requirements separately

✅ Select drying and filtration based on air quality

1:1 direct drive

The direct-drive design distinguishes the D Series from the belt-driven F models. This page does not focus on comparing all rotary screw compressors, but rather on the specific selection of a fixed-speed direct-drive unit mounted on a base frame.

Buy a direct-drive rotary screw compressor on a base frame

If you’re looking to purchase a rotary screw compressor with a 1:1 direct drive mounted on a base frame, you can compare the ten performance levels based on the required flow rate and operating pressure. The peripheral equipment is added separately to match the overall system.
