Frequently Asked Questions
How much air does the ELGi EQ37 V produce?
The ELGi EQ37 V produces up to 237 CFM at 100 PSI. The available airflow range depends on the pressure configuration:
- 63-237 CFM at 100 PSI
- 55-209 CFM at 125 PSI
- 45-188 CFM at 150 PSI
This wide operating range allows the compressor to automatically adjust output as facility air demand changes.
What is the advantage of the VFD on the ELGi EQ37 V?
The Variable Frequency Drive allows the compressor motor to change speed based on actual compressed air demand. When your facility requires less air, the compressor reduces output and energy consumption. When demand increases, the compressor increases output automatically.
For facilities with changing air demand, a properly sized variable speed compressor can provide significant energy advantages compared with operating a fixed-speed compressor at partial load.
Is the ELGi EQ37 V designed for continuous-duty operation?
Yes. The EQ37 V is an industrial rotary screw compressor designed for demanding applications where compressed air is required throughout the production day.
It is well suited for manufacturing, CNC machining, fabrication, woodworking, automotive, automation, and other industrial compressed air applications.
What pressure configurations are available for the EQ37 V?
The ELGi EQ37 V can be configured for 100 PSI, 125 PSI, or 150 PSI operation.
Selecting the proper pressure configuration is important because compressor airflow changes with operating pressure. Compressed Air Advisors can help determine the correct pressure and CFM requirements for your application.
How loud is the ELGi EQ37 V?
The EQ37 V has a published sound level of approximately 70 dB(A). Its enclosed cabinet helps reduce compressor noise compared with open industrial compressor designs.
Does the ELGi EQ37 V include factory startup?
Yes. Free factory-authorized startup is included when purchasing the EQ37 V from Compressed Air Advisors Online.
Factory-authorized startup provides professional commissioning after the compressor has been installed and is ready to operate.
What warranty is included with the ELGi EQ37 V?
The ELGi EQ Series includes a 5-year 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?
It depends on the facility's compressed air demand.
A variable speed compressor is generally most beneficial when air demand changes significantly throughout the day. The compressor can reduce motor speed and energy consumption when less compressed air is required.
Facilities with relatively constant air demand may be better suited to a fixed-speed rotary screw compressor. Proper compressor sizing and understanding the facility's actual air-demand profile 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, receiver tank size, refrigerated or desiccant air dryer, filtration, drains, and piping required for the application.
