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!
