When choosing a professional car wash machine, maximum pressure alone is not enough. Daily vehicle volume, washing time per vehicle, water flow rate and daily operating hours should all be considered.
For this reason, when comparing professional car wash machines, the actual workload of the business should be one of the main selection criteria.
Which Car Wash Machine Should You Choose by Daily Vehicle Volume?
| Vehicles per Day | Recommended Pressure | Usage |
|---|---|---|
| 1–10 vehicles | 150 bar | Low intensity |
| 10–20 vehicles | 150–200 bar | Medium intensity |
| 20–40 vehicles | 200 bar | Intensive professional use |
| 40+ vehicles | 200–250 bar | Heavy and continuous use |
These values provide a general guide for businesses mainly washing passenger cars and light commercial vehicles.
Is 150 Bar Enough for 1–10 Cars per Day?
For dealerships, workshops and smaller car wash businesses with a low daily vehicle volume, a professional 150 bar machine may be sufficient.
The JSK-150 150 bar cold water car wash machine offers an 11 L/min water flow rate and 220 V operation, making it suitable for low to medium workloads.
What About 20–40 Cars per Day?
As daily vehicle volume increases, the machine operates for longer periods. Pump quality and water flow therefore become increasingly important.
The JSK-200 200 bar professional car wash machine provides a 14 L/min water flow rate and a 5.5 kW motor, making it a strong option for busy professional car wash businesses.
A 200 bar system also provides a balanced working range for businesses washing passenger cars, light commercial vehicles and fleets.
What If You Wash More Than 40 Cars per Day?
At 40–50 vehicles per day or more, simply increasing maximum pressure may not be enough.
During busy periods, a second machine or an additional washing bay may provide more capacity.
Businesses that regularly clean commercial vehicles, construction machinery or heavily soiled equipment can consider the JSK-250 250 bar pressure washer, which provides higher pressure and a 15 L/min water flow rate.
Water Flow Is as Important as Pressure
Pressure helps loosen dirt, while water flow removes the loosened dirt from the surface.
This is why a professional machine should not be selected only according to 150, 200 or 250 bar. As daily vehicle volume increases, sufficient water flow and professional pump quality become more important.
You can compare available models in the cold water car wash machines category.
When Is Hot Water Necessary?
If the business regularly deals with oil, grease and stubborn contamination, increasing pressure alone may not provide the best solution.
In these applications, hot and cold water car wash machines can provide more efficient cleaning.
Conclusion
1–10 vehicles: 150 bar
10–20 vehicles: 150–200 bar
20–40 vehicles: 200 bar
40+ vehicles: 200–250 bar or a multi-machine system
The right professional car wash machine should ultimately be selected according to vehicle type, operating hours, water flow, motor power and peak workload, not daily vehicle volume alone.
