The Hyundai HY27550X is a 1500W, 2HP portable electric air compressor featuring a 50-litre steel tank designed for low-noise operation in DIY and trade environments. Running on a slow-speed 1450 RPM motor, it delivers an air displacement of 11CFM (300 L/min) and a maximum discharge pressure of 100psi (7 bar) without the need for oil lubrication. This compact unit comes equipped with Euro quick release connectors, twin pressure gauges, and wheels for transport.
- Motor Power: 1500W (twin 750W motors) producing 2HP for reliable performance.
- Tank Capacity: 50-litre steel receiver provides a substantial air reserve.
- Air Output: Delivers 11CFM displacement and 5.28CFM Free Air Delivery (FAD).
- Operating Pressure: Maximum discharge pressure of 100psi / 7 bar regulated via twin gauges.
- Low Noise Operation: Emits 60dB at 7 metres using a slow-running 1450 RPM 4-pole motor.
- Oil-Free Pump: Diaphragm system requires no lubrication, ensuring zero risk of oil contamination.
Low-Noise 1450 RPM Motor Technology
The compressor utilises a slow-running, 4-pole motor that operates at 1450 RPM. This lower operational speed reduces mechanical wear and tear on internal components compared to standard piston compressors, contributing to a longer service lifespan. The configuration also minimises energy consumption during operation and keeps the output volume to 60dB at a distance of 7 metres, making it suitable for home workshops and garages.
Oil-Free Maintenance and Air Quality
Equipped with oil-less diaphragm pumps, this unit eliminates the requirement for regular oil changes or lubrication checks. The oil-free design ensures that the compressed air supply remains free from oil contamination, which is essential for applications such as spray-painting. This system simplifies ongoing maintenance, requiring users only to drain accumulated moisture from the tank using the bottom valve.
Pressure Management and Delivery
An automatic stop-start pressure control system regulates the motor to maintain consistent pressure within the 50-litre steel tank. Output pressure is managed through a twin-gauge regulator, allowing users to monitor both tank and line pressure accurately. Air delivery is handled via standard Euro quick-release connectors, enabling rapid swapping of air tools and lines.
Workshop Mobility and Compliance
With a net weight of 39kg, the compressor is fitted with two large wheels, a front transport handle, and two rubber-mounted anti-vibration feet to assist with movement around a workspace. The unit operates from a standard 230V supply using a 1.5-metre cable with a 13A UK plug. For safety compliance, the pressure relief valves are updated to the latest CE certification standards.
