HK 650-90 Pro twin-piston compressor 11 bar 5.5 HP/4 kW 400V 468 l/min 90 l
The HK 650-90 Pro is an efficient piston compressor designed for intensive work in workshops, service businesses and small industrial plants. A 5.5 HP (4 kW) motor, a three-phase 400V supply and a 90 l tank give this model high output and reliability. The K25 compressor pump provides a long service life and efficiency, even in demanding applications.
K25 compressor pump: durability and output
- K25 compressor pump: made in the European Union, the K25 pump offers high efficiency at an optimised speed, which extends its service life and reduces component wear.
- Optimised speed: 1184 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 vanes supports the cooling system.
- Durable components: a cast-iron block and a reinforced cylinder head stand up to heavy use and extend the service life of the unit.
Advantages of the HK 650-90 Pro
- Ready to use: the compressor comes with a Condor pressure switch with thermal protection and a power cable with plug, so you can connect it quickly and use it right after installation.
- Metal belt guard: the open-structure belt guard ensures an optimal flow of cooling air, which improves cooling and protects the drive.
- Resistance to high temperatures: a copper pressure pipe assists cooling, so the unit keeps working efficiently even in tough conditions.
- Noise reduction: a high-efficiency intake filter of innovative design effectively quietens the compressor for more comfortable work.

Applications
The HK 650-90 Pro is an excellent choice for running air tools, inflating and light spray painting. With its three-phase 400V supply it performs best where a permanent connection to the 400V mains is available, which makes it a versatile machine for industrial and workshop use.
Efficiency and duty cycle
The HK 650-90 Pro is designed for a 50%/50% duty cycle: the compressor runs for 50% of the time and rests for the remaining 50%, which lets the unit cool down. The optimised speed and efficient cooling system lower running costs by reducing energy consumption and noise. The solid construction ensures long service with minimal maintenance costs.
Warranty and reliability
The HK 650-90 Pro is covered by a 3-year warranty, which supports its durability and reliability even under heavy use. It is made in the European Union from high-quality components and runs trouble-free in tough conditions.
