25–150HP EPM Series Variable Speed Permanent Magnet Screw Air Compressor
Up to 40% Power Savings for Facilities with Fluctuating Air Demand
The Anest Iwata EPM Series extends variable speed, permanent magnet efficiency into the 25–150HP range, giving larger industrial operations a compressor that can save up to 40% of power compared to an equivalent fixed-speed unit. The more an facility’s air demand fluctuates through the day, the faster that efficiency translates into payback — typically within just 1–2 years.
A newly over-sized compression airend delivers more air per kilowatt than conventional designs, efficient enough that some facilities can step down to a lower kW compressor altogether. Once the system reaches working pressure, it stops rather than continuing to run off-load, and an average RPM 40–50% lower than competing models reduces mechanical wear over the compressor’s lifetime — all while a variable speed soft start keeps the impact on the power grid to a minimum.
APPLICATIONS
- Larger industrial operations with 25–150HP air demand
- Facilities with fluctuating or unpredictable air demand
- Operations looking to cut electricity costs and peak-load grid impact
- Industries requiring a reliable, constant compressed air supply
- Facilities aiming to downsize to a lower-kW compressor without losing output
KEY FEATURES
- Saves up to 40% of power compared to an equivalent fixed-speed compressor
- Payback in as little as 1–2 years, faster where air demand fluctuates most
- Over-sized compression airend delivers more air per kilowatt
- No offload running — the compressor stops once it reaches working pressure
- Low RPM, averaging 40–50% lower than competitor models
- Keeps a constant air supply regardless of fluctuating demand
- Variable speed soft start for less impact on the power grid
- VSD-permanent magnet efficiency throughout the operating range
FAQ
How much can I actually save in power with the EPM Series?
The EPM Series can save up to 40% of power compared to an equivalent fixed-speed compressor, with savings scaling higher the more your facility's air demand fluctuates.
How quickly does the EPM Series pay for itself?
Payback is typically achieved in as little as 1–2 years, with faster paybacks in facilities where air demand varies significantly throughout the day.
What does 'no offload running' mean, and why does it matter?
Once the compressor reaches working pressure, it stops rather than continuing to run without producing useful output — unlike fixed-speed units that often keep running off-load, wasting energy.
How does the over-sized airend improve efficiency?
The larger compression airend delivers more air per kilowatt than a standard design, which is efficient enough that some facilities can use a lower kW compressor than they otherwise would need.
Is the EPM Series suitable for facilities with constant, unchanging air demand?
It still delivers strong efficiency and low RPM operation in constant-demand settings, but the biggest power and payback advantages come through in facilities where air demand fluctuates.
