HK 425-50 Pro two-cylinder piston compressor 10 bar 3 HP/2.2 kW 400V 317 l/min 50 l
The HK 425-50 Pro is a professional piston compressor for heavy use in workshops, service businesses and small industrial plants. A 3 HP (2.2 kW) motor, a three-phase 400V supply and a 50 l tank give it steady, reliable operation and high output. Its K17C compressor pump provides durability and efficiency, even under heavy loads.
K17C compressor pump: durability and output
- K17C compressor pump: manufactured in the European Union, the K17C pump works efficiently at an optimised speed, which gives a long service life and reduces component wear.
- Optimised speed: 1250 rpm keeps the compressor running steadily, minimises the risk of overheating and allows longer compression cycles.
- Advanced cooling: enlarged intercoolers and aftercoolers effectively lower the temperature of the compressed air, and a belt pulley with cooling fins supports the cooling system.
- Durable components: cast-iron cylinders and a reinforced cylinder head withstand heavy use and extend the life of the unit.
Advantages of the HK 425-50 Pro
- Ready to use: the compressor has a Condor pressure switch with thermal protection and a power cable with plug, so you can connect it quickly and use it as soon as it is installed.
- Metal belt guard: the open design of the belt guard gives a good flow of cooling air, which improves cooling and protects the drive.
- Resistance to high temperatures: a copper pressure pipe assists cooling and keeps the compressor efficient in difficult conditions.
- Noise reduction: a high-efficiency intake filter of innovative design reduces operating noise and makes work more comfortable.

Applications
The HK 425-50 Pro is well suited to running air tools, inflating and small painting jobs. With its three-phase 400V supply it works best where it can stay permanently connected to a 400V network, which makes it versatile across industrial and workshop applications.
Efficiency and duty cycle
The HK 425-50 Pro is designed for a 50% - 50% duty cycle: the compressor runs for 50% of the time and rests for the other 50%, which lets the unit cool down. The optimised speed and efficient cooling system keep running costs down by reducing energy use and noise. The solid construction ensures a long service life with minimal servicing costs.
Warranty and reliability
The HK 425-50 Pro is covered by a 3-year warranty, which backs its durability and reliability under heavy use. Made in the European Union from high-quality components, it runs without trouble in difficult conditions.
