Q1. How to choose the right air compressor?
While selecting the right air compressor for your application, a few points to
consider are the compressor’s life cycle cost, capacity and air quality required by
the application.
Q2. How Does an Air Compressor Work?
The Air compressor runs on electric power and produces pressurised air that
powers several machines for various applications. An air compressor compresses
atmospheric air in a closed chamber, thereby increasing its pressure which is then
delivered through the outlet. Different compressors use rotary or reciprocating
action for the compression process.
Q3. How Often Do I Need to Change the Oil in My Air Compressor?
In an oil-lubricated air compressor, checking the oil every three months or per
your compressor’s manual is recommended. In a rotary screw compressor, it is
recommended to check the oil every 4000 to 8000 hours. Always follow ELGi’s air
compressor maintenance manual for the guidelines on oil changing.
Q4. How to Reduce Your Compressed Air Costs?
Frequently checking for leaks, preventive maintenance practices and turning off
the air compressor when not in use may result in significant cost savings.
Additionally, redesigning the pipeline to shorten the distance travelled by air in
the compressed air system ensures optimal airflow and reduces pressure drops,
further helping save on operating expenditure. Connect with our experts to help
you optimise your compressed air usage.
Q5. How to Service and Maintain Your Air Compressor?
To achieve the optimal functioning of the air compressor, keeping a check on the
component and changing them on time with spare parts from OEMs is crucial.
Some common parts needing replacement are dust filters and oil separators,
airline filter cartridges, and lubricating oil. Get in touch with your nearest ELGi air
compressor dealer in Mumbai for your service requirements.
Q6. How to Calculate the Right CFM or Airflow for Air Compressors?
Small pneumatic tools usually need up to 5 CFM at 4.8-6.2 bar. In contrast, the
more extensive equipment demands more than 10 CFM at 6.9-8.2 bar. In the case
of multiple applications with different airflow demands, add up their individual
requirement and consider the total usage to be 40-50% higher than the obtained
number to ensure the air compressor doesn’t run at full capacity.
Q7. What are the Energy Tips for your Air Compressor?
A few points to assess to save on energy bills are – setting the air compressor at
the lowest possible pressure for your application, changing filters on time,
cleaning the compressed air system regularly, heat recovery and performing
quarterly maintenance checks and air audits.
Q8. How to Choose the Right Piston Air Compressor? (Belt Drive or Direct Drive)
Belt-driven reciprocating compressors are conventional machines proven for their
durability in irregular usage patterns over the years. On the other hand, direct
drive machines are quieter, more compact and suit a higher duty cycle with
proven reliability.
Q9. Do You Need a Reciprocating Compressor or a Rotary Screw Compressor?
Several factors influence the selection of the air compressor for your application.
One of them is the duty cycle. Reciprocating air compressors could be suitable for
the low-duty cycle, whereas the rotary screw could be more suited for high-duty
cycle applications.
Q10. How to Select an Oil-Free Air Compressor for Your Business?
Numerous factors determine the compressor selection for your business. A few
factors to keep in mind are criticality of the application, airflow requirements and
operating pressure.
