Underdeck air compressors is another name for PTO driven air compressors, a compressed air system that is powered by a vehicle’s transmission via a PTO. PTO air compressors are frequently nicknamed “underdeck” because of their mounting position, under the deck of a service truck.
Underdeck air compressors come in hydraulic and non-hydraulic varieties, giving operators options depending on their specific needs. Most hydraulic varieties are intended for service trucks with hydraulic cranes, tool circuits, and outriggers, while non-hydraulic underdeck air compressors work well for countless applications.
What are the advantages of underdeck air compressors?Underdeck air compressors are an innovative solution for providing compressed air and have many benefits over traditional above-deck air compressors. The advantages of underdeck air compressors include:
- Free up cargo space
- Reduce GVW
- 50 to 200 CFM
- 100% duty cycle
- Hydraulic option
- Few moving parts
- Less maintenance
Who makes underdeck air compressors?There are three primary manufacturers of underdeck air compressors in North America:
How much do underdeck air compressors cost?The exact price of an underdeck air compressor will vary depending on a variety of factors, including the manufacturer, dealer mark-up, region, specific technology, and more. In addition, there are two different factors that determine the cost of any vehicle-integrated air compressor:
- System price
- Install price
Here are a couple of examples from VMAC’s product line of estimated install times for an experienced upfitter:
