4.8 AIR SYSTEM

Pressurized air is used to operate the opening and closing of the gate(s) on the trailers through a series of components: filter, oiler, electric solenoid, tank(s), cylinder(s) and lines. All components work together to control the gates.

4.8.1 FILTER AND OILER

*CLAM ONLY

The air system is designed with a filter and an oiler to remove contaminants from and add a light oil mist to the air supply.

A. Filter:

The self draining filter insures that only dry air is used to move the air cylinders for opening and closing the discharge gates. Any moisture in the air will wear the seals and packing in the cylinder or freeze in cold weather. Check daily, drain if required.

B. Oiler:

The oiler introduces a fine oil mist into the air stream as it moves into or through the cylinder. The oil mist lubricates all the internal and moving cylinder components. Without oil, the seals and wipers in steel cylinders will dry out and wear rapidly until the cylinder fails.

Keep oil in the oiler at all times.

Establish the oil consumption rate for your application and add oil before the oiler is empty. Refer to Section 5.2.16 for filling and adjusting procedure.

Check the oil level on a daily basis.

NOTE: Composite cylinders do not require filter and oiler

NOTE: The standard cylinder on the CUL trailers is the composite cylinder, hence oilers are not required.
