MORE SPACE. MORE PURPOSE.

UNDERHOOD Air Compressors provide the necessary air needs and save space for other tools and equipment.

When space is at a premium and uptime is non-negotiable, service fleets choose UNDERHOOD air compressors. Joe recommends them to his fleet customers when they need reliable, compressed air and maximum space savings. 

UNDERHOOD
Customer Spotlight

For Joe Gosnick, Director of the Truck Equipment Division at Fallsway Equipment Company, space savings is a key reason customers choose UNDERHOOD air compressors. By locating the compressor in the engine compartment, fleets preserve valuable space in the truck body for tools and equipment. This gives Fallsway more flexibility when building service trucks, creating room for an additional toolbox, a welder, or other equipment the customer needs. The result is a truck equipped with dependable, on-demand air and more room for the job.
