Surprisingly quiet, which will help if I forget to turn it off and it starts up in the small hours. It is pretty powerful - buzzed off the wheel nuts my previous compressor struggled with. Very well made and the dual compressor system is elegant. Competitively priced - so all good really! Compressor Care:Pressure safety valves on Hyundai air compressors have been updated in compliance with the latest CE certification standards. The pressure release pull ring has been removed from the safety valve to prevent it from being misused to drain the air from the compressor tank, causing excessive wear to the valve. Air and moisture should always be released using the drain valve located on the bottom of the tank.

With a 50-litre tank capacity, this compressor provides an air displacement of 10CFM/300 litres per minute and a maximum pressure of 7bar/100psi. Air Flow (FAD) 150 litres/minute 6CFM. litre tank capacity provides an air displacement of 11CFM/ 300 litres per minute and a maximum pressure of 100psi / 7bar.

Summary

Open the box, screw on the wheels, the feet and the air filters and it was all set to go - took 10 minutes. Powerful compressor utilises two 750W motors Lighter than most other conventional piston-type compressors Designed for professionals needing power off grid Designed for DIY and trade applications the HY7524 silenced oil-free air compressor is ideal for spray-painting, blowing away dirt and dust, nailing, inflating tyres or operating air tools. Lightweight Compressor I'm a long time DIYer and have owned a 25ltr compressor for around 20 years. It started getting less reliable so I looked around for an alternative. The 'silent' range caught my eye and I nearly went for a like for like replacement - in the end I upgraded to the 50Ltr model.

This maintenance free compressor uses oil free diaphragm pumps to produce a clean air supply and considerably reduce noise compared to conventional piston compressors. With a 50 litre tank capacity this compressor provides an air displacement of 11CFM/ 300 litres per minute and a maximum pressure of 7 bar/ 100psi. The noise level is such that i dont need to raise my voice and it cant be heard outside of the garage at all which is all i can ask for. I out it under a workbench and it muffled it further so its barely noticable over the various hums from other equipment in my garage.Mcgraw 21-Gallon air compressor review Here’s a brief comparison between the Hyundai HY27550 and the alternative RocwooD 50L compressor Overall, it would be great if the manufacturer improved the wheels and filter, but its nice they included either so i cant complain and the actual compressor itself is great. Oil Free - The compressor doesn't use oil. There's therefore no risk of oil contaminating the air supply, as can happen with compressors which use oil. These types of air compressor are particularly suitable for sensitive environments where it’s imperative that oil doesn’t pass through tools, such as food production areas and medical facilities. They are also suited to DIY, garages and workshops for powering air tools, inflating tyres and other general uses.

The Hyundai HY27550 240V 2x750W 2hp 50L Air Compressor is designed for professional landscapers, gardeners, mechanics and also DIY enthusiasts. This powerful compressor utilises two 750W motors to achieve fantastic power and performance. In addition to the motor the 50 Litre capacity air tank provides an air displacement of 11CFM/ 300 litres per minute and a maximum pressure of 100psi / 7bar. Whether you are spray painting, blowing away dirt and dust, inflating tyres or operating air tools, the HY27550 has you covered. Hyundai claims the Hyundai HY27550’s maximum tank pressure is 100PSI/7BAR. The maximum tank pressure of air compressors means that the tank can safely store air at around 100 PPSI. Pressure recovery time OF the Hyundai HY27550 Great little compressor, using it for midi spraying with small CFM gun and general tools. So much quieter than my old direct drive on, very happy. To understand the practical performance of this Hyundai HY27550, we tested it with running standard HVLP paint sprayers and 3/8 and 1/2 inch air impact wrenches. The air requirements of these tools were around 10 to 20 CFM. So, you might be understood how the Hyundai HY27550 performed. The compressor capacity is okay to run a 3/8 impact wrench for a short time, but it is not a better option for a continuous run. litre tank capacity provides an air displacement of 11CFM/ 300 litres per minute and a maximum pressure of 100psi / 7barWith a 50 litre tank capacity this compressor provides an air displacement of 11CFM/ 300 litres per minute and a discharge pressure of 7 bar/ 100 psi. Suitability - The Hyundai HY27550 Air Compressor is suitable for home, professional and workshop use. It's ideal for spray painting, blowing away dirt/dust, nailing, inflating tyres, operating air tools, etc. It's an easy to use, lightweight and highly portable machine.

Can't really comment on the capacity as I've only used for dusting so far but seems a LOT more capable than my old Clarke Warrior and at about half the noise level.

The pressure control system automatically stops and starts the motor to maintain the pressure in the air tank and comes with a twin gauge air pressure regulator. WOW ... SO impressed. It fills in about the same time my old 25 ltr took it is SO quiet (for a compressor). I'd say something similar to a modern washing machine.
