Frequently Asked Questions
What parts are available for the PowerFlex™ series?
PowerFlex™ maintenance parts cover four service categories: compressor components (filters, separator elements, compressor oil), Kubota® D902 engine parts (oil and fuel filters), air system accessories (reservoir tanks, regulators, moisture separators), and battery and fuel system components. Browse by category above or go to your model’s part page for a full part number list.
What are the standard PowerFlex™ maintenance intervals?
All diesel PowerFlex™ models follow three core service intervals: an initial 50-hour break-in service (KIT1285), a 200-hour or annual Kubota® engine service (KIT1154-01), and a 500-hour or annual compressor service (KIT1153). The PowerFlex™ AE Gas follows the same compressor intervals on a gasoline engine service schedule.
How do I know which PowerFlex™ model I have?
The model name and machine number are printed on the serial number plate located on the unit enclosure. Have that number ready before ordering parts. Each model’s parts page includes a machine number table that maps configuration details to the correct part numbers.
Can I use the same maintenance kit across all PowerFlex™ models?
The three core compressor and engine maintenance kits apply across all diesel PowerFlex™ models (AE, AEH, AH) because they share the same Kubota® D902 engine and rotary screw compressor platform. The PowerFlex™ AE Gas uses a different engine service kit. Confirm compatibility of your machine model before ordering.
What compressor oil do PowerFlex™ machines require?
All PowerFlex™ rotary screw air ends require Vanguard™ Premium Rotary Screw Compressor Oil (264626-1GAL). Using non-approved oils can void the lifetime warranty on the air end and accelerate separator element degradation. Do not substitute with generic compressor oils.
