Pressurizer is short for cab air pressurizer. A pressurizer is added to work equipment to keep excess amounts of dust, etc. out of the cab interior

A pressurizer works by drawing in outside air, filtering it, and venting it into the cab.  As the pressurizer moves air into the cab, air escapes through loose or open windows, doors or other gaps in the cab. The steady outflow of air keeps dust from entering the cab.  Small tightly sealed cabs will require less air volume than large leaky ones.
