Frequently Asked Questions

Is the K11-50 built to handle tough Australian conditions like heat, dust, and frequent use?

Yes. The K11-50 Professional Series Compressor is designed for Australian conditions, with twin cast-iron cylinders, an Italian-made “K” series pump, and heavy-duty components built for long service life.

The K11-50 specifications list a free air delivery of 191 L/min, a 1.5 kW (≈2 HP) motor, a 50 L receiver, and a maximum pressure of 1000 kPa (≈145 psi), making it ideal for light industrial and professional trade applications.

What safety, durability, and compliance features are included?

The K11-50 model includes overload protection on the motor, a low-speed pump design to reduce vibration and wear, and an air receiver manufactured to AS1210-3 standards for workplace safety compliance.

What warranty and after-sales support do I get, particularly for Sydney customers?

Pilot Air provides a 5-year warranty on the compressor pump and 1 year on other components, backed by local service and spare parts through their Sydney service division.

How portable is the unit, and what are its size and weight considerations?

The K11-50 technical details show a compact 50 L receiver, dimensions of 830 × 400 × 750 mm, and a weight of 55 kg, making it portable for workshop use but still requiring stable placement with good ventilation

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!
