Pilot Air Idle Down Pistons
Ensure your system is working at the correct speed with our idle-down pistons. Bringing the revs of the engine down to idle, the pistons ensure both air compressor and engine are working at a reduced speed.

Frequently Asked Questions
What are Idle-Down Pistons and how do they help in Australian conditions?
Idle-Down Pistons reduce engine revs to idle when the compressor reaches cut-out pressure, lowering stress on the engine and compressor. This helps save fuel, reduce heat, and minimise wear — important for tough Australian worksites.
Which piston models are available and which compressors do they fit?
The Idle-Down Piston spares range includes UIP-160 for Honda GX160 (K17P/K17PS), UIP-225 for Kohler, UIP-270 for Honda GX270 (K25PR/K25P), and UIP-340 for Honda GX340/GX390 (K30P), ensuring correct fit for different trade and industrial units.
Why should I choose genuine Pilot Air Idle-Down Pistons over aftermarket parts?
Using genuine Pilot Air spares guarantees proper fit and materials designed for Pilot Air’s pneumatic load/unload and idle-down systems, maintaining warranty coverage and ensuring long-term reliability.
How quickly can I get Idle-Down Pistons if I’m in Sydney or elsewhere in Australia?
Pilot Air holds stock for immediate dispatch, and through its Australia-wide spare parts network you can access fast delivery whether you’re in Sydney, regional NSW, or interstate.
How do I know when my Idle-Down Piston needs replacing?
You may need a replacement if the compressor idles poorly, revs fluctuate around cut-in/cut-out pressures, fuel use increases, or the unit runs hotter than usual. You can check the correct part for your model via the Idle-Down Piston spares listing and consult Pilot Air’s service team if unsure.
Pilot Air Reviews
We have a growing manufacturing business and our air supply needed to be upgraded to deliver to a clean volume of air to specific machines and mainly our spray booth. 3 Months ago the team at Pilot Air evaluated our requirement and delivered an excellent solution, we have had time to run the system for a considerable time and found it to be excellent. Also Australian Manufactured to boot. Very Happy.

My husband recently bought a second hand Trademaster 12 air compressor in need of some maintenance. He took it to the Silverwater servicing centre with no prior arrangement. The staff were polite, obliging, and eager to help, and he was impressed with the service provided. Well done Pilot Air!

Thanks Pilot Air! We have just purchased our third pilot compressor (K50). Our oldest one (K25) is 14 years old and still going strong, used all day every day only replaced pressure switch.
