Frequently asked questions
Common questions about EMAX from 3G Electric.
What is the difference between EMAX two-stage and single-stage air compressors?
EMAX two-stage compressors, such as the ESPR07V080V3-208, compress air in two stages to achieve higher pressures and better efficiency at 175 psi. Single-stage models are typically used for lower-pressure applications. Two-stage units generally have lower operating temperatures and can deliver more cfm per horsepower. The product line includes both configurations, with two-stage models available from 5 hp to 15 hp.
Are EMAX quiet pressure-lubricated compressors suitable for indoor use?
Yes. The quiet pressure-lubricated series includes a factory silencer and a pressure-lubricated pump that reduces noise compared to splash-lubricated designs. These compressors are commonly installed in automotive shops, garages, and maintenance areas where noise levels are a concern. However, proper ventilation and clearance are still required for motor cooling and air intake. Consult the installation manual for specific clearance and ventilation requirements.
What voltage and phase options are available for EMAX electric air compressors?
EMAX electric air compressors are available in single-phase 240V and three-phase 208/230V or 460V configurations. For example, the ESPR10V080V1 is a 10 hp single-phase 240V model, while the ESPR15V120Y3-460 is a 15 hp three-phase 460V unit. The correct voltage and phase must be specified at the time of order, as motors are not field-convertible. 3G Electric can assist in matching the compressor to the available power supply.
Do EMAX air compressors include aftercoolers or dryers?
Some EMAX models include a radiator aftercooler, such as the ESPR15V120Y3-208. An aftercooler reduces the temperature of compressed air and helps remove moisture before it reaches downstream equipment. Not all models include this feature; it is typically found on higher-horsepower or specific configurations. For applications requiring very dry air, an additional refrigerated or desiccant dryer may be necessary. Check individual product specifications for aftercooler inclusion.
What is the maximum pressure rating for EMAX two-stage compressors?
Most EMAX two-stage electric air compressors in the quiet pressure-lubricated series are rated for a maximum pressure of 175 psi. This is a common working pressure for pneumatic tools, tire service, and general shop air. The actual delivered cfm varies by model and motor horsepower, ranging from 17 cfm at 5 hp to 57 cfm at 15 hp. Always verify the pressure rating and cfm at the intended working pressure for your specific tools.
Can EMAX generators be used for standby power during outages?
EMAX portable generators are suitable for temporary power supply during outages or at remote job sites. They are not intended for continuous prime power unless specifically rated for that duty. For standby applications, proper transfer switches and grounding are required. 3G Electric supplies EMAX generators with various output capacities; consult the model specifications for continuous and surge wattage ratings to match your load requirements.
