VSD/VFD & Direct-Drive Oil-Injected Screw Compressors

Reliable, efficient and application-specific compressed air solutions for industrial applications.

PRODUCT OVERVIEW

Gurudev Enterprises offers VSD/VFD and Direct-Drive Oil-Injected Screw Compressors under the Intello Kompressor brand for industrial applications requiring reliable, efficient and application-specific compressed air solutions.

A Variable Speed Drive (VSD) Oil-Injected Screw Compressor uses a variable frequency drive to control the speed of the compressor motor according to the required compressed air demand.

Instead of continuously operating the motor at a fixed speed, the VSD system allows the compressor to increase or decrease its speed as air demand changes.

Oil is injected into the compression chamber to provide lubrication, cooling and sealing during the compression process.

Frequently Asked Questions – VSD/VFD & Direct-Drive Screw Compressor

Find answers to common questions about VSD/VFD, Direct-Drive technology, maintenance and services.

What is a VSD/VFD Oil-Injected Screw Compressor?
A screw compressor that adjusts motor speed according to compressed air demand.
What is a Direct-Drive Oil-Injected Screw Compressor?
A screw compressor where the motor transfers power directly to the airend.
What is the difference between VSD/VFD and Direct-Drive compressors?
VSD/VFD controls motor speed, while Direct-Drive describes the power transmission arrangement.
Can a compressor have both VSD and Direct-Drive technology?
Yes. Some compressor designs combine variable-speed control with direct-drive technology.
When should I choose a VSD screw compressor?
VSD is particularly suitable when compressed air demand varies significantly.
What are the advantages of Direct-Drive technology?
It eliminates conventional belt-and-pulley transmission and reduces belt-related maintenance requirements.
What spare parts are available for these compressors?
Filters, oil separators, compressor oils, valves, sensors, seals, electrical components and model-specific service parts are available.
Do you provide compressor repair and servicing?
Yes. Gurudev Enterprises provides compressor repair, servicing, troubleshooting and preventive maintenance support.
Do you provide AMC for screw compressors?
Yes. Annual Maintenance Contract services are available for planned preventive maintenance and ongoing support.
How do I select the right screw compressor?
Selection depends on FAD/CFM, working pressure, HP/kW, air-demand pattern, operating hours, application and future requirements.
