Car Wash Systems

Fan Wheels for Drying Blower in Car Wash Tunnel and Gantry Systems

Car washes are used to clean dirty vehicles. Regular cleaning and care helps preserve the paint and protect it from environmental influences, which has a positive effect on maintaining the value of the car. Among the different types of car washes, gantry car washes, drive-thru car washes and self-service car washes are the most widespread in the world. In gantry car washes or tunnel car washes, the individual cleaning steps are arranged in stations one after the other. The vehicle is pulled through the carwash on conveyor belts and cleaned by the various washing instruments such as underbody wash, rim sprayer, textile rollers, blower dryer, etc.

Drying blowers for gantry car washes, drive-thru car washes and tunnels dry the vehicle after cleaning, often by means of contour-following movements close to the vehicle through targeted air guidance. Energy-efficient drying blowers for roof dryers, side drying or pre-dryers must generate high flow velocity - with low noise emission - and have low power consumption at the same time. At the same time, drying blowers for car washes should be able to withstand the aggressive ambient conditions and have a small installation space to guarantee the most space-saving system design possible.

Car Wash Fan Wheels

Highly efficient, low-noise and compact fan wheels from punker help carwash manufacturers achieve high flow velocity in the dryer nozzles and thus an optimum drying result. At the same time, power consumption remains low in the main operating mode. The fan wheels, made of powder-coated aluminum, are corrosion-resistant and, thanks to their low weight, ideally suited for flexible arrangements or orientations of the blower. Due to its lightweight construction, it requires a lower starting current than industry standard steel blower wheels. The combination of airfoil blade geometry and optimized inlet cone ensures low noise emission. Thanks to the reduced depth of the inlet cone, particularly space-saving housing designs can be realized. The Car Wash fan wheels have been tested for cyclic operating conditions to simulate applications with a high number of start-stops, such as are common in car washes.


Reduced noise impact on the environment and immediate surroundings
thanks to noise-optimized airfoil geometry of the fan impellers.

Savings in energy costs and insulation
possible, as the airfoil fan impeller blades ensure high energy efficiency with low noise emission.

Optimum drying result
When used in the specially matched scroll housing, high energy efficiency and blow-out speed are generated, enabling fast and thorough drying.

Reduction of service costs due to the long service life of the fan wheels
which can be achieved thanks to corrosion protection of the coated aluminum and high strength confirmed in cycle tests.

Case Study Car Wash

The client approached punker with the request for an alternative impeller, which fits their existing housing and performs equally or better than the existing impeller. punker designed a solution based on an efficient and quiet impeller with aluminum airfoil blades and a corresponding inlet cone. Practical field tests in the car wash systems showed that this combination delivers similar air speed with less power consumption and less noise.
