Only attempt to shorten the supplied hose if there is access to the
appropriate equipment. Do not attempt to cut the hose and splice it
using hose clamps.
VMAC Compressor oil will degrade rubber lined hoses, use only
hoses with an AQP elastomer type liner. Contact VMAC Technical
Support at 1-888-241-2289 for further information.
The PTFE tubes and AQP elastomer lined hoses are specifically designed to work
with VMAC compressor oil and at compressor operating temperatures.
Dependant upon the desired location of the AOST, the hose lengths provided with
this system may not be ideal. VMAC suggests first trying to adjust the AOST within
its mounts to take up any excess slack in the hoses. If this is not effective, the
hoses can be shortened or replaced as necessary, or hose extenders can be used.
VMAC recommends shortening these hoses as a preferred alternative to coiling up
and securing the excess.
Shorter hose length will maximize system performance.
Avoid using 90° fittings wherever possible as they cause flow
restrictions and negatively impact performance.

•
