ER 90-250 VF PM 2s series two-stage screw compressors
Ventajas
BETICO's ER 90-250 VF PM 2s TWO STAGE compressors with permanent magnet motors are characterized by high efficiency and reliability.
These high power compressors normally work 24 hours. They are designed with the most efficient solutions, have two-stage rotors with intermediate cooling, permanent magnet motors, direct coupling between the motor and the rotor without gears or bearings and the regulation of the air flow generated by speed variation that adapts the flow generated to the demand.
In addition to high-efficiency compressors, we provide expert technical advice, analysing each installation to offer customized solutions that optimize energy consumption.
Our direct FABRICA-CLIENT Technical Assistance Service guarantees complete maintenance and compliance with all current regulations, providing safety and maximum efficiency in your compressed air network.

BETICO ER 90-250 VF PM 2s series industrial screw compressors are characterized by:
- High efficiency in the design and manufacture of our compressors we employ the most efficient optimized innovative solutions.
- Newly designed V-profile rotors of the latest generation have the best volumetric efficiency, with an ideal contact line.
- Large size and low speed rotors Large size rotors in 5/6 format, machined with extreme precision (0.005 mm), improve performance compared to traditional 4/6 format rotors.
- 1:1 direct drive The rotor of the electric motor is coupled directly to the male screw shaft, which has a special design that is longer than usual. This configuration eliminates the need for gears, bearings in the electric motor and cooling fan, improving performance by more than 5% over traditional assemblies.
- Nd-Fe-B permanent magnet motors: Meet the ULTRA PREMIUM IE-5 standard, ensuring maximum energy efficiency.
- Oil-cooled electric motors, the motor is cooled with the same oil that cools the compressor, the oil is passed through the motor before reaching the rotor, which ensures that the motor operates at an optimum temperature regime.
- Special frequency inverters for compressors optimized for the needs of screw compressors and permanent magnet motors.
- Robust and simple design, these compressors have been designed to work 24 hours/day at full load in environments that may contain a large amount of dust in suspension and at temperatures of more than 40ºC common in southern Europe.
- Simple and economical maintenance, all parts of the compressor requiring maintenance are easily accessible, the high quality of the components ensures a very long component life.
- Low noise level, the low rotor speed ensures that the minimum noise level is generated, which together with a bodywork with high density soundproof panels, allows a conversation to be held next to the compressor at normal volume.
