Frequently asked questions

What makes the OFP5.5SI built for Australian working conditions?

The OFP5.5SI Oil-Free Industrial Silent compressor has an oil-less design, sealed bearing conrods, PTFE compression rings, heat-insulated piston pin bushings and specially anodised cylinder coatings, plus a high-efficiency cooling system and integral aftercooler — all engineered to withstand heat, dust, and continuous heavy-duty use typical in Australia.

How quiet is the OFP5.5SI — is it suitable for urban areas like Sydney?

Yes — the OFP5.5SI runs at approximately 67 dB(A) thanks to its super-silenced cabinet and acoustic foam-lined panels, making it appropriate even in workshop or industrial settings in and around Sydney.

The OFP5.5SI delivers about 730 L/min free air, uses a 5.5 kW (7.5 HP) motor, operates at up to 800 kPa (≈116 psi), and comes with robust construction — enough power and reliability for demanding Australian industrial tasks

What support and service can I expect locally in Sydney / New South Wales from Pilot Air?

Pilot Air has its Head Office & Manufacturing in Silverwater, Sydney, plus a Service & Spares Division in Auburn, offering fast spare parts delivery and local support for customers of the OFP5.5SI across NSW and beyond.

What warranty and standards does the OFP5.5SI comply with?

The OFP5.5SI carries a 1-year warranty on the complete unit, meets ISO 8573-1:2010 Part 1 for oil content, and uses a MEPS-approved motor to help ensure energy efficiency and regulatory compliance.

Our 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!
