Description of Components

Subsystems

The Boss 8060 UBI PTO air compressor system is a group of subsystems that are shipped loose to be mounted in open
spaces on the vehicle's frame and body. The subsystems are connected using hoses and tubing that are also shipped in
the kit. Not all vehicles are capable of being equipped with a Boss 8060 UBI PTO air compressor system. Please contact
your local distributor to verify your vehicle is capable of supporting the Boss 8060 UBI PTO air compressor system.

Compressor Assembly

The heart of the Boss 8060 UBI PTO air compressor system is the rotary
screw airend. The rotary screw is
device employing one stage of compression to achieve the desired
pressure. In operation, two helically grooved rotors mesh to compress air.
Intake air is trapped as the male lobes roll down the female grooves,
pushing trapped air along, compressing it until it reaches the discharge
port in the end of the stator. This delivers smooth-flowing, pulse-free air
to the sump tank.
The oil in a rotary screw airend serves three purposes:
• Lubricates the rotating parts and bearings.
• Serves as a cooling agent to remove the heat from compression.
• Seals the running clearances.
Mounted to the airend is a companion flange, intake valve, and mounting bracket.

Sump Tank Assembly

The air oil mixture leaving the compressor assembly flows into the
sump tank assembly. The sump tank is the first stage of oil
separation in the 8060 UBI PTO compressor system. The sump
tank also acts as an oil reservoir to ensure there is plenty of oil
capacity to handle continuous air compressor operation.
The tank safety relief valve is located at the top of the sump tank.
This valve acts as a backup to protect the system from excessive
pressure buildup as a result of a system malfunction.
Also in the tank assembly is the oil fill cap and oil level sightglass.
