Quizplus · Accepted Answer

Both technicians are correct. Precleaners are used on work trucks that operate in dusty conditions to remove larger particles and debris from the incoming air, preventing them from clogging the engine air filter. By removing these larger particles, the main engine air filter can last up to three times longer, as stated by Technician B.
