This is our mobile cascade trailer.  The trailer is equipped with a Breathing Air System cascade system.    This particular unit has four 6000 psi bottles capable of filling two SCBA bottles at one time.  We installed a two bottle blast chamber located at the rear to be used while filling the bottles.  The trailer also has an onboard gas operated compressor.  This unit can be used to keep the system full if out on a long scene.  We also have storage for up to 16 spare bottles.
