Compressed air
 Less
means more!
Conventional electricity generators and compressors use their own
motors needing their own tank, casing, frame, exhaust system, etc .
These heavy components require high maintenance - intensive, lower the
payload capacity
of your vehicle and occupy a lot of valuable cargo bay. The systematic
solutions from Carryboy offer and provide an enormous saving of space and
weight in your service vehicle.

 ELECTRICTY POWER GENERATION

Weve got

The mobile generation of electricity

development work and is the essential base for many CAD drawing underfloor mounting kit
producers for special-purpose vehicles to achieve their special fixtures and
extensions.

We have various compressor solutions
which are chosen depending on the set-up compressed air system
of the vehicle concerned.

 Advantages of the underfloor compressed air system
The advantages of our underfloor compressor
system are similar to those in our modern power generation
systems. Conventional solutions need an extra motor and By connecting the PTO to the compressor or
