Permanent Magnet Screw Compressor
This rotary twin screw compressor is driven by a permanent magnet motor.
What This Machine Does
This rotary twin screw compressor is driven by a permanent magnet motor. Its energy saving performance is better than an ordinary high frequency motor, and it holds a high motor power even at low speed, which is where a plant compressor spends most of its working life.
Key Benefits
- High motor power maintained at low speed, unlike an ordinary high frequency motor
- Integrated permanent magnet motor about one third the size of a conventional motor
- Energy efficiency meeting GB19153-2009 energy saving product standards
- Compact installation that is easy to install and disassemble for service
- Main parts optimised through finite element analysis
Problems It Solves
- Compressors running at full power when demand is only partial
- Large motor frames taking up plant room space
- Energy bills dominated by compressed air
- Component quality that varies across the machine
Who It Is For
- Grain and rice processing plants
- Food factories with pneumatic equipment
- Packing operations
- Plants reviewing energy consumption
Application Scenarios
- Plant air for optical sorters and pneumatic ejectors
- Packing line pneumatics
- General plant air in grain and food processing
- Sites replacing an oversized fixed speed compressor
Technical Features
- Rotary twin screw airend with permanent magnet motor
- Permanent magnet motor rotor with integrated motor and shaft structure
- Finite element analysis applied to the main parts
- Energy efficiency to GB19153-2009 energy saving product standards
- High efficiency retained across the speed range

| Engineering | Main parts optimised by finite element analysis |
| Series | JF series twin screw compressor |
How This Machine Is Built
Quality Control
- Component quality optimised through finite element analysis of main parts
- Energy efficiency verified against the GB19153-2009 standard
- Machine run tested before shipment
Customisation Options
- Capacity selected from the total plant air demand
- Installation arrangement for the available plant room
- Supply voltage confirmed for the destination
Use Guide
- Add the air demand of every machine before selecting capacity
- Allow a margin for future sorters or packing equipment
- Keep the cooling airflow around the cabinet unobstructed
- Service the airend on the recommended interval
How It Compares With The Alternatives
| Ordinary high frequency motor compressor | Holds high motor power at low speed and takes about a third of the motor volume. |
|---|---|
| Oil free water lubricated compressor | Lower purchase cost where the process can accept a lubricated machine. |
Permanent Magnet Screw Compressor Questions
Why a permanent magnet motor?
It keeps a high motor power at low speed, which is where most plant compressors run, and the integrated motor is about a third of the size of an ordinary high frequency motor.
Does it meet an efficiency standard?
Energy efficiency meets the GB19153-2009 energy saving product standards.
Is the air oil free?
No. For oil free air, use the TTC water lubricated range.
How is the machine engineered?
Main parts of the JF series twin screw compressor are analysed by finite element analysis to optimise component quality.
How do I size the compressor?
From the combined air consumption of the sorters, packing machines and plant pneumatics, plus a margin.
