I purchased a DPF (Diesel Particulate) https://machtrade.us/category/washing-equipment/washing-equipment-for-service-stations/cleaning-machines-en/ cleaning machine a few months ago and it has been one of the best equipment investments for my auto repair shop. This machine has greatly simplified the maintenance and cleaning of DPF filters on diesel vehicles. It works quickly and efficiently, and I no longer spend a lot of time on manual cleaning. Thanks to this car, my clients can be sure of the quality service of their cars.
