ROI Calculator
Estimate fuel savings by replacing a compressor-powered King PC with a King E-Max XT. This calculator uses estimated average 80% loaded fuel figures for diesel air compressors.

3-Year Estimated Savings: $0
This calculator uses estimated average 80% loaded fuel figures for diesel air compressors. Estimates assume an 8-hour coating day and a 25 kW diesel generator for the King E-Max XT. Actual savings vary by job site, fuel price, equipment condition, load profile, and utilization.
Remote Jobsite Fuel Comparison
The biggest fuel consumer on most coating jobsites is not the sprayer — it's the compressor. Compressor fuel figures below use estimated average 80% loaded operation.
| System | Fuel / 8-hr Day | Daily Fuel Cost | Extra Daily Cost vs. E-Max XT |
|---|---|---|---|
| King E-Max XT + 25 kW Generator | ~12 gal | $54 | Baseline |
| King PC + 185 CFM Compressor | ~18 gal | $79 | +$25/day more |
| King PC + 375 CFM Compressor | ~38 gal | $173 | +$119/day more |
| King PC + 750 CFM Compressor | ~74 gal | $331 | +$277/day more |
| King PC + 900 CFM Compressor | ~80 gal | $360 | +$306/day more |
| King PC + 1100 CFM Compressor | ~86 gal | $389 | +$335/day more |
| King PC + 1600 CFM Compressor | ~154 gal | $691 | +$637/day more |
Assumption: Compressor fuel burn is modeled using estimated average 80% loaded fuel figures from the diesel air compressor fuel burn reference, converted to an 8-hour coating day.
“The bigger the compressor, the bigger the electrification opportunity.”
In-Shop & In-Plant Applications
In a shop, the value shifts to reducing shop air demand, improving energy efficiency, and reducing production risk.
Power Comparison — Same Spraying Work
| System | Power Required |
|---|---|
| King PC (6500 air motor, ~55 HP compressor) | 40.7 kW |
| King E-Max XT | 7.2 kW |
| Reduction | ~82% |

Other Shop Benefits
- Reduce compressor wear and downtime risk
- Free up compressor capacity for other production equipment
- Eliminate air dryers, filtration, and moisture management for spray power
- Eliminate compressed-air supply hoses (and hose-whip safety risk)
- Aging compressors lose efficiency — electric avoids that decline
“Just because compressed air is available doesn't mean it's free.”

When To Sell Electric
✓ Ideal Fit
- Coating-only projects, tank relines, water/wastewater, roofing, waterproofing
- Contractors who own or rent 375 CFM or larger compressors
- Paint shops with centralized shop air or aging compressors
- Contractors focused on reducing fuel and operating costs
! Qualify Carefully
- Jobs requiring blasting and priming: The blast and prime phase will still require a compressor, but subsequent coating applications can go electric — allowing the compressor to be returned, redeployed, or shut down once blasting is complete.
- Buyers focused only on purchase price: Reframe the conversation around total Cost of Ownership (COO) — fuel, maintenance, rental, transport, downtime, and air-system support all add up over the life of the equipment.
- Customers unfamiliar with electric (offer a demo)
× Stay With Air-Powered
- Hazardous-location (HazLoc) applications — with one exception: the King E-Series is the only electric sprayer that IS HazLoc certified. For HazLoc jobs outside the King E-Series, air-powered remains the recommended solution.
Field Cheat Sheet
- Lead With No compressor. One power source. Lower operating cost.
- Remote Same coating work. 12 gal vs. estimated 18–154 gal per 8-hr day using average 80% loaded compressor fuel figures.
- Shop 40.7 kW vs. 7.2 kW — about 82% less power.
- Service Compressor: ~10,000 hrs | Generator: ~30,000 hrs.
- Power Range 6.5 kW small units up to 40 kW fully loaded plural systems.
- Differentiator Graco proprietary XT motors, built in USA, backed by Graco.
- HazLoc Air-powered is the default for HazLoc — except the King E-Series, the only HazLoc-certified electric.
“If you can eliminate the compressor, simplify the jobsite, reduce operating cost, and still get the performance required — why wouldn't you try electric?”
