DEPRAG turbine technology – one drive, 3 power levels
Our powerful turbines promise high torques in every application. Even under load, the integrated speed controller ensures a constant speed. Our compact turbine drives are the perfect choice for various applications. For example, they are suitable as air starters for small and medium-sized combustion engines and gas turbines. They also provide a powerful drive in drilling machines, grinding and milling tools.
With our turbines, we offer energy-efficient, high-speed drives that are suitable for continuous operation and guarantee low air consumption with an optimum power-to-weight ratio.
The highlight: the output of our turbine motors can be flexibly adjusted to 1.5 kW, 3.0 kW or 4.5 kW. Our drives are available with speeds of 80 - 3,400 revolutions per minute.
Advantages of our turbine motors
Thanks to the adjustable output (1.5kW - 3.0kW - 4.5kW), our turbines offer maximum flexibility and achieve nominal speeds of 70 - 2880 rpm.
- Oil-free operation
- Optimum power-to-weight ratio
- Low air consumption

Our turbines generate electricity even from small amounts of process gases.
With a low investment outlay, you can convert your existing residual energy into electricity and thus significantly reduce your commercial electricity consumption. Click below to find out more about the turbine generator.
Using a turbine for an aircraft emergency door
The pyrotechnic ignited, indirect turbine drive with reduction gearing is used for the PYROTAK emergency door system. This system offers a high power-output by a very small-sized turbine.
Use case 1: turbine grinder application
Use of a high-speed turbine in a turbine grinder
- Power = 250 W
- Free Speed = 70,000 1/min
Use case 2: turbine grinding machine
A two-stage curtis turbine is used for this turbine grinder. When compared to multi-stage overpressure turbines, this grinder has a simple layout and is especially cost effective. The deciding advantage for this application is the extreme low weight.
- Power = 2.2 kW
- Free Speed= 12,200 1/min

FAQ & technical information on the turbine
Design and functionality of a turbine motor
Pneumatic turbines are continuous-flow machines, which can be executed in single-stage or dual-stage design.
The conversion of the pressure energy into kinetic energy takes place in the inlet nozzle. On a two-stage turbine, the largest part of the kinetic energy is converted in the 1st turbine wheel. The air-flow is diverted over the stationary turbine wheel. The remaining energy is converted in the 2nd turbine wheel.
The turbine does not require any contact seals. Therefore, the operation of the turbine with non-lubricated compressed-air is totally free from wear. Continuous-flow machines optimally utilize the energy of the compressed air. Therefore, the air requirement of a turbine motor is 1/3rd less when compared to an pneumatic vane motor. The power to weight ratio [kg/kW] is only half.
Our advanced DEPRAG turbine technology uses the expansion of compressed air extremely efficiently: compared to a vane motor, efficiency increases of up to 40% can be achieved. To drive a turbine motor with an output of 4.5 kW, the same amount of air is required as to operate a vane motor with only 3.2 kW. This increases your productivity and saves valuable energy.
