Product detailed description
WALTER VWK650-5,5/270P Vertical Cast-Iron Piston Compressor
The VWK650-5,5/270P is the vertical version of the mid-range WALTER series. The 2V twin-cylinder cast-iron unit has a power input of 4.0 kW (5.5 HP), intake of 630 l/min and an effective delivery of 550 l/min at 10 bar. It operates at 993 rpm – the first in the range to drop below 1,000 rpm – and features a vertically mounted 270 l tank.
270 l is the largest capacity available for a vertical WALTER model; only the most powerful vertical, the VWK900-7,5/270P, shares this volume, while lower-class verticals have 90 l. This provides you with full air reserves and a slow-running unit designed for continuous operation, but with a significantly smaller footprint than its horizontal counterpart. Power supply 400 V / 50 Hz, noise level approx. 80 dB(A), 3-year warranty upon registration at waltercesko.cz.
Configuration of this machine
- Cast-iron unit — 2V · 993 rpm · single-stage compression
- Pressure vessel — 270 l · vertical
- Vertical design — Vertical tank — smaller floor footprint
- Three-phase 400/50 V/Hz
- Standard pressure of 10 bar for common pneumatic tools
Why choose this model
The same machine as the horizontal version, just built vertically
The unit, motor, and tank have the same parameters as the horizontal WK650-5,5/270P: 993 rpm, 550 l/min delivery, and 270 l reserves. You are not buying a different technical level; you are buying a different configuration.
270 l reserves in a vertical design
Verticals in the 2.2 and 3.0 kW classes have a 90 l tank; only the most powerful vertical model, the VWK900-7,5/270P, has the same 270 l. With a 2 bar difference between the cut-in and cut-out pressure, you get approximately 540 l of free air per cycle – at a continuous draw of 200 l/min, this means roughly 14 motor starts per hour. The tank does not increase power, but it is precisely during these starts that a piston compressor wears down.
Best intake-to-delivery ratio among ten-bar platforms
Of the 630 l/min of intake air, 550 l/min flows into the distribution system, which is approximately 87%. No other WALTER 10-bar platform has a higher ratio – it is 81% for the 2.2 kW entry class and 84% for the 5.5 kW class.
A high centre of gravity requires a level floor
A vertical 270 l tank represents significant mass within a narrow footprint. Place the machine on a level, solid concrete floor, never shim individual feet, and anchor it according to the manual in halls where trolleys operate. Compare the installation dimensions with the clear height of your workshop before ordering.
Who is it for
The typical buyer is a car repair shop, body shop or paint shop with two workstations, where air flows for several hours a day and the only available space is a strip along the wall. It is equally suitable for metal fabrication companies that have expanded their machinery and no longer have space for a horizontal machine with wheels. 550 l/min will cover an impact wrench and blow-off in tandem or a spray gun in continuous operation.
Typical applications
- Fixed air distribution throughout the workshop – the machine stands against the wall and does not obstruct the aisle for a pallet truck
- Body shop with a lift, where the floor is occupied by equipment and only a strip along the wall remains for the compressor
- Paint shop or preparation area, where the air source must be located outside the main working area
- Joinery with a sliding table saw and extraction – staplers and sanders have plenty of reserve in 270 l
- Metalworking shop with continuous demand at one workstation and peaks at another
- Replacement for an ageing machine where the new workshop layout no longer accommodates a horizontal tank with wheels
Where to choose a different model
You want to move the machine around the workshop or transport it between facilities
The horizontal WK650-5,5/270P has an identical unit, but a tank on wheels with a handle. You will take up more floor space, but gain mobility and a lower centre of gravity during handling.
You need more than 550 l/min continuously – two grinders, or two workstations running at full capacity in tandem
Stick with the vertical version and go for the VWK900-7,5/270P with 740 l/min. It is the most powerful vertical version in the series and has the same 270l tank.
You have a low ceiling, low doors or an installation in an attic
The vertical version extends upwards. If you are unsure about the height, choose the horizontal version WK650-5,5/270P with the same power and tank capacity.

Frequently asked questions
- How exactly does it differ from the horizontal WK650-5,5/270P?
- Only in the orientation of the pressure vessel and the resulting installation dimensions. Power input of 4.0 kW, intake of 630 l/min, delivery of 550 l/min, pressure of 10 bar, speed of 993 rpm, two cylinders 2V and tank volume of 270 l are identical for both machines. The horizontal version has a tank on wheels with a handle; the vertical stands on feet against the wall.
- Does the vertical version have a shorter lifespan due to vibrations?
- It does not – the unit, its mounting, and the speed are the same as the horizontal version, and 993 rpm is significantly lower than 1,276 rpm in the entry-level class, so the vibration itself is minimal. Correct placement is essential: a flat, solid floor, no improvised shimming of the feet, and anchoring according to the manual for permanent installation.
- How is condensate drained from the vertical 270-litre tank?
- Water flows naturally to the lowest point, so it is drained more thoroughly in the vertical version than in a horizontal tank, where it spreads across the bottom. The valve is located at the bottom under the tank – ensure free access to it and prepare a bowl or a hose leading to a collection container. For 270 l in continuous operation, drain at least once a week, preferably more often.
- How much floor space do I actually save compared to the horizontal version?
- A horizontal machine of this class occupies a floor strip across the full length of the tank, plus space around the wheels and handle. A vertical tank of the same volume takes up approximately half the footprint and can be placed against the wall. Precise dimensions for both versions can be found in the technical specifications of the products.
- Can the machine be transported horizontally?
- The machine is shipped on a pallet as a whole and cannot be carried by hand – plan for a forklift, ramp, or enough personnel for unloading. Follow the manual for transport and handling: with an oil-filled unit, not every position during transport is risk-free. Check the shipment before signing.
The machine comes with a 3-year warranty after registration with the importer. Warranty terms, the maintenance schedule and a comparison of all 28 models are in the category WALTER cast-iron piston compressors.
Ventilek’s tip
Same heart as the horizontal six-fifty, just standing tall. A footprint smaller than two pallets, with output for spraying and an impact wrench.
