ELGi EQ30 V – 40 HP Variable Speed Rotary Screw Air Compressor

Variable Speed Efficiency. Industrial Reliability. Built for Changing Air Demand.

The ELGi EQ30 V 40 HP Variable Speed Rotary Screw Air Compressor is an industrial-duty compressed air solution designed for manufacturing facilities, fabrication shops, CNC operations, woodworking plants, automotive facilities, and other demanding applications where compressed air demand changes throughout the workday.

Featuring an integrated Variable Frequency Drive (VFD), the EQ30 V automatically adjusts compressor output to match the facility’s actual compressed air demand. When air consumption drops, compressor output is reduced. When production demand increases, the compressor responds by increasing output. This makes the EQ30 V an excellent option for facilities looking to reduce unnecessary energy consumption while maintaining dependable system pressure.

The EQ30 V is available in 100 PSI, 125 PSI, and 150 PSI configurations, with airflow ranging from 45 to 191 CFM, depending on the selected operating pressure. ELGi’s EQ Series is engineered for demanding industrial environments where reliability, serviceability, operating efficiency, and long equipment life are important.

Frequently Asked Questions

How much air does the ELGi EQ30 V produce?

The ELGi EQ30 V produces up to 191 CFM at 100 PSI.

Airflow depends on the selected operating-pressure configuration:

• 63-191 CFM at 100 PSI
• 55-182 CFM at 125 PSI
• 45-144 CFM at 150 PSI

The variable speed drive allows compressor output to change as compressed air demand increases or decreases.

What is the advantage of the VFD on the ELGi EQ30 V?

The integrated Variable Frequency Drive allows the compressor motor to adjust speed according to actual compressed air demand.

When your facility requires less compressed air, the compressor can reduce output and power consumption. When demand increases, compressor output automatically increases.

This makes variable speed technology particularly useful in facilities where air demand changes significantly throughout the day.

Is the ELGi EQ30 V designed for industrial use?

Yes. The EQ30 V is designed for industrial compressed air applications including manufacturing, CNC machining, metal fabrication, laser cutting, woodworking, automotive service, automation, and production machinery.

The EQ Series incorporates heavy-duty filtration, high-ambient cooling, an industrial enclosure, and a severe-duty TEFC motor for demanding operating environments.

What pressure configurations are available for the EQ30 V?

The EQ30 V is available in 100 PSI, 125 PSI, or 150 PSI configurations.

Choosing the correct pressure is important because available airflow decreases as operating pressure increases. Compressed Air Advisors can help determine the proper pressure configuration based on your equipment requirements.

How loud is the ELGi EQ30 V?

The ELGi EQ30 V has a published operating sound level of approximately 70 dB(A).

The enclosed cabinet helps reduce compressor noise compared with open industrial compressor designs.

What electrical power does the EQ30 V require?

The EQ30 V configuration shown here is designed for 460V, 3-phase, 60 Hz electrical service.

Does the ELGi EQ30 V include factory startup?

Yes. Free factory-authorized startup is included when purchasing the ELGi EQ30 V from Compressed Air Advisors Online.

A factory-authorized technician performs the commissioning after the compressor has been properly installed and is ready for startup.

What warranty comes with the ELGi EQ30 V?

The ELGi EQ Series includes a 5-year complete package warranty and 6-year airend warranty, with no service contract required.

Terms and conditions apply.

Is a variable speed compressor better than a fixed-speed compressor?

That depends on your compressed air demand.

A variable speed rotary screw compressor is generally best suited for facilities where air demand fluctuates throughout the day. It can reduce motor speed and energy consumption when less compressed air is required.

A fixed-speed compressor may be appropriate when compressed air demand remains relatively constant.

Proper compressor sizing and understanding your actual compressed air demand are important when choosing between fixed-speed and variable-speed equipment.

Can Compressed Air Advisors help size the complete compressed air system?

Yes. Compressed Air Advisors can help determine the proper:

• Compressor capacity
• Operating pressure
• Air receiver size
• Refrigerated or desiccant air dryer
• Compressed air filtration
• Condensate drains
• Aluminum piping system
• Capacity for future expansion

We can help make sure the compressor and downstream equipment are properly matched to the application.
