A pair of new Atlas Copco GA18 FF rotary screw compressors are heading out the door to their new home.

Built for continuous-duty operation, rotary screw compressors are a great fit for facilities that need a steady, reliable supply of air throughout the day. These particular 25 hp units also include integrated refrigerant dryers and water separators, helping deliver clean, dry compressed air in one compact package.

Just some of the many benefits of Atlas Copco rotary screw compressors:

Energy-efficient operation — especially important because energy is typically the biggest lifetime cost of producing compressed air.

Quieter, smoother operation — lower noise and vibration can make rotary screws easier to place near production areas.

Compact footprint — strong air output without taking up excessive floor space.

Lower maintenance demands — fewer wear-intensive components than reciprocating designs can mean less routine service and downtime.

Connect with an EVAPAR compressed air sales specialist and learn how a rotary screw compressor can be a boost to your facility.

EVAPAR recently completed startup of the new Generac Industrial Energy standby power system at this medical device manufacturing facility, featuring eight 500 kW diesel generators engineered to provide up to N+2 redundancy for the facility’s most critical loads, including life-safety systems.

The installation also includes four Lakeshore transfer switches, a FloTronics fire pump ATS, and a redundant load-shedding and permissive control system designed to support reliable operation when it matters most.

From system integration through startup, projects like this from EVAPAR demonstrate the level of planning, coordination, and technical expertise required to protect critical operations.

For engineers building standby and emergency power systems, Generac's Power Design Pro™ provides a practical way to evaluate generator sizing and system performance during the design process.

The software helps users account for motor starting, load sequencing, voltage and frequency dip, harmonics, and other factors that can influence generator selection.

Power Design Pro also allows engineers to model electrical loads, analyze transient performance, evaluate load-shedding strategies, compare different system configurations, and develop project specifications in one platform.
It’s a useful resource for working through generator sizing requirements before equipment is specified.

EVAPAR recently commissioned this Generac Industrial Energy 400 kW diesel generator — accompanied by a separate 80 kW — with Generac TX transfer switches at Southwest Indiana's newest welcome center, providing dependable standby power for the facility and the supporting systems needed to keep it operating for travelers during an outage.

From equipment selection and installation support through startup and commissioning, projects like this are about making sure backup power is ready to perform when utility power isn’t.

If compressed air demand in your facility changes throughout the day, why pay to run your compressor at full speed when you don’t need it?

Atlas Copco Variable Speed Drive (VSD) compressors automatically adjust their operating speed to match actual air demand, helping reduce wasted energy while maintaining consistent system pressure.

With electricity accounting for roughly 70% of an industrial compressor’s total cost of ownership, those efficiency gains can make a significant difference.

Depending on the application, VSD technology can reduce compressor energy costs by 35–50%, delivering meaningful operating savings and helping offset the higher initial investment.

Talk with EVAPAR'S expert air systems sales team about whether VSD technology makes sense for your compressed air system.
