SECTION 8 − COMPRESSOR SYSTEM
8-1. Air Compressor System Integration
A. General Information − Minimum Requirements
For use with a mechanics truck crane, the system should at a minimum include the following items:
1 Reservoir of 20 gal (76 L) or more capacity
2 Safety relief valve
3 Properly sized hoses and fittings, restrained and protected
Depending on the desired compressed air quality, air conditioning components such as separators, filters or dryers may be required.
No check valve should be installed.
B. Reservoir
Required reservoir size is 20 gal (78 L) or larger. Compressor performance may be adversely affected if tank is less than 20 gal (78 L). The addition of an
air reservoir provides air delivery capacity and aids in reducing the amount of water and contaminates discharged to the rest of the system by condens-
ing out these contaminants. The reservoir should be ASME Code for 200 psi working pressure. A drain valve should also be installed for draining water
and contaminants.
The reservoir must have a safety relief valve installed of appropriate relieving pressure and capacity of the system. Also, relief valve must comply with
vessel and code under which the vessel is constructed and inspected.
C. Hoses And Fittings
Obtain hoses of the proper length and type with appropriate fittings for the installation according to Table 8-1.

0.5 / 12.7 350 / 2.41 1400 / 9.65 − 40 to 100
D. Compressor Oil
Mobil 1 Synthetic ATF is recommended. Do not mix oil types.
The cooling oil must have high ageing stability, corrosion protection, and dispersive capacity; low emulsification tendency, and minimum foaming. Vis-
cosity class ISO VG 68 is recommended.
