HK 650-90 Pro twin-piston compressor 11 bar 5.5 HP/4 kW 400V 368 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. With a 5.5 HP (4 kW) motor, a three-phase 400V supply and a 90 l tank, this model offers high output and reliability. Its K25 compressor pump gives it a long service life and efficient operation, even in demanding applications.
K25 compressor pump: durability and performance
- K25 compressor pump: Made in the European Union, the K25 pump works efficiently at an optimized speed, which extends its service life and reduces component wear.
- Optimum speed: A speed of 1184 rpm keeps the compressor running steadily, minimizes 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: The cast iron block and reinforced cylinder head stand up to intensive use, which extends the life of the unit.
HK 650-90 Pro advantages
- 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 straight after installation.
- Metal belt guard: The open design of the 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 compressor keeps working efficiently even in difficult conditions.
- Noise reduction: A high-efficiency intake filter of innovative design effectively dampens compressor noise and makes the machine more comfortable to work with.

Applications
The HK 650-90 Pro is well suited to powering air tools, inflating and small painting jobs. Because it runs on a three-phase 400V supply, it works best where a permanent 400V connection 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 optimized speed and efficient cooling system make the compressor economical to run, with lower energy consumption and less noise. Its solid construction ensures long-term use with minimal servicing costs.
Warranty and reliability
The HK 650-90 Pro compressor comes with a 3-year warranty, which backs its durability and reliability even under intensive use. Made in the European Union from high-quality components, it runs trouble-free in difficult conditions.
