Product detailed description
Direct drive 1:1
The SCR-PM series compressors are equipped with highly efficient ALLY WIN screw blocks, which were designed in Germany and have several international patents. The screw block is connected directly to the main electric motor by a tapered coupling, so that there are no losses in the gear train.
IE4 permanent magnet motor
The permanent magnet electric motors used are modern motors with very high efficiency IE4 according to IEC EN 60034, which increases the motor efficiency by up to 3% compared to the motors used in conventional compressors. In addition, the motors are perfectly oil-cooled even at low speeds and thanks to the high IP65 electrical protection, they offer perfect protection against dust and moisture. In addition, the PM motor design does not contain any bearings, which eliminates the maintenance aspect of the motor.
Continuous speed control
Thanks to the infinitely variable speed control by the inverter, considerable savings are made, especially by eliminating idling and the possibility to adjust the compressor output pressure.
SCR9000 electronic unit
The modern unit with 7" colour touch screen and communication in Czech language with perfect software allows many user settings, display of machine operation parameters and reporting of possible malfunctions.
Ventilation with speed control
The SCR-PM compressors are equipped with a ventilation system with switching and cooling control according to the needs of the machine. In addition to saving energy, SCR-PM compressors can operate at temperatures up to +45 °C and with very low outlet air temperatures.
Pipes instead of hoses
On SCR-PM compressors you will find only metal tubing instead of traditional rubber hoses. This saves you money on hose replacements in the future and eliminates the risk of hose rupture and subsequent air or oil leaks as much as possible.
Effective oil separation
Thanks to the three-stage oil separation by centrifugal force, gravity and a separation filter, the compressor outlet is highly conditioned compressed air with an oil content of

SCR is the compressor brand of the Chinese company Shanghai Screw Compressor Co., Ltd, a joint venture with Japan’s ANEST IWATA since 2018. We offer series from 2.2 to 280 kW: oil-free scroll and screw machines, compact workshop compressors and two-stage machines for continuous operation.
Most SCR series come with a variable speed drive as standard and a permanent magnet motor coupled directly to the airend, without belts. The machine holds pressure by adjusting its speed and does not waste energy running unloaded. Where air comes into contact with food or medicine, choose the oil-free XA and G series.

SCR-XA — oil-free scroll
Class 0 air in smaller volumes. Two scrolls compress the air without touching, so there is no lubricant in the compression chamber.
- 2.2–29.6 kW, 200–3,520 l/min
- from 55 dB(A) on the smallest model
- Class 0 verified by TÜV Rheinland
SCR-APM Mini — for the workshop
The smallest SCR screw machine. A permanent magnet motor drives the airend directly and the inverter matches speed to demand.
- 3.6–5.8 kW, up to 690 l/min
- stand-alone, 3-in-1 or with filtration
- 7″ IT7000 touch display
SCR-APM Maxi — workshop and production
The same technology, one size up. A stand-alone machine or a package on a 270 or 500 l air receiver with dryer and filtration.
- 7.5, 11 and 15 kW
- up to 2,000 l/min at 10 bar
- 4-in-1 and 8-in-1 packages
SCR-EPM — for shift work
Direct drive and inverter from 15 kW. One machine covers 7, 8 and 10 bar and holds pressure within ±0.1 bar.
- 15–45 kW in six sizes
- up to 9,500 l/min
- SCR9000 controller with weekly schedule
SCR-G and GV — oil-free screw
Oil-free air in large volumes. Two screw stages run dry, and the machine is air- or water-cooled.
- 37–280 kW, 7, 8 and 10 bar
- Class 0 to ISO 8573-1
- GV with variable speed drive
SCR-EPM2 — heavy industry
The main machine of the compressor room. Seven sizes with a permanent magnet motor, inverter and flanged outlet.
- 55–160 kW
- up to 33,500 l/min
- cascade of up to 16 machines without a master controller
SCR-H and HPM — two-stage
For plants that never stop. Air is compressed in two stages with intercooling, so each cubic metre takes less electricity.
- 132–280 kW
- pressure up to 12.5 bar
- less than 3 ppm oil in the air
SC Oil 46 M — SCR oil
Genuine lubricant for oil-injected machines. ISO VG 46 mineral oil for SCR screw compressors.
- change every 4,000 operating hours
- 5 and 20 l canisters
- drum for several machines

The maximum air delivery is that of the largest machine in the series at the lowest pressure, measured to ISO 1217. It falls as pressure rises.
How to choose an SCR compressor
1. Work out consumption
Add up the consumption of tools and machines that run at the same time, plus a margin for leaks in the pipework. Choose the compressor by litres per minute, not by kilowatts.
2. Choose the pressure
Most tools need 7 or 8 bar. Each extra bar costs about 7% more energy, so do not buy pressure “just in case”.
3. Decide on oil
Food, pharmaceuticals, electronics or paint shops need oil-free air: the XA or G series. Other plants are fine with an oil-injected machine and filtration.
4. Add a receiver and drying
An air receiver evens out peaks and drying removes water from the pipework. The APM series combine both with the compressor on one frame.
Frequently asked questions
- Who makes SCR compressors?
- Shanghai Screw Compressor Co., Ltd, founded in Shanghai in 2000. It employs more than 250 people, over 10% of them engineers, and its factory covers more than 80,000 m². Production is certified to ISO 9001, the machines carry CE marking for Europe and UL for the US market, the oil-free machines hold a Class 0 certificate, and there is an SGS efficiency certificate as well.
- What does SCR have to do with ANEST IWATA?
- In 2018 SCR formed a joint venture with Japan’s ANEST IWATA. ANEST IWATA dates back to 1926, has been listed on the Tokyo Stock Exchange since 1973 and makes compressors, vacuum equipment and coating equipment. The SCR-XA scroll compressors use ANEST IWATA airends.
- How has the SCR range developed?
- SCR has built screw compressors since 2000. It added oil-free screw machines in 2008, a series with permanent magnet motors in 2015, and magnetic bearing centrifugal compressors in 2020.
- Oil-free or oil-injected?
- In an oil-injected machine the oil is in the compression chamber, and filtration downstream only reduces what is left. There is no oil in the compression chamber of the oil-free XA and G series, so the air meets Class 0 to ISO 8573-1. The two-stage H series is oil-injected but lets less than 3 ppm of oil into the air.
- What do the letters in the model name mean?
- For example SCR-15/10APM-500FF: 15 kW, 10 bar, APM series, 500 l air receiver and FF equipment with dryer and filtration. The suffix D stands for a package with air receiver and dryer. In the G series, W means water cooling and V a variable speed drive; in the H series, HPM is the version with an inverter.
- Which oil goes into an SCR compressor?
- Oil-injected SCR screw compressors take SC Oil 46 M mineral oil, viscosity grade ISO VG 46. It is changed every 4,000 operating hours, and we sell it in 5 and 20 l canisters and in a drum. The XA scroll compressors need no oil.
