Why equipment size matters
Automotive equipment is often rated by capacity, current, airflow, pressure, or vehicle class. Choosing too little capacity can make a job slow or ineffective, while choosing equipment far beyond the job can add unnecessary cost and bulk. Projectlyst narrows the starting range so you can verify the final choice against the vehicle and manufacturer requirements.
