Air-O-Flite Air-O-Flite
Each of the 2 air tanks has a large 2850 cu. in. capacity. On the right is an RV-1 valve that keeps air pressure at 40 psi and a simple ball valve shut-off with a one-way check valve to prevent air bleed-off as shown in the first picture to the right.
Air-O-Flite:
The manual system control valve  is located in the main control box as shown in the second picture to the right.
The lane control manifold with heavy-duty shut-off valves and compression-type weatherhead fittings separate the air supply to the lanes to the right is a second RV-1 valve for additional overload protection as shown in the picture below.
A plastic liner is installed between the air bag and rollers to protect the air bag from debris. The snug fit of the plastic liner against the main frame allows vacuuming to remove debris. Air-O-Flite systems include a one-piece double-jacketed air bladder as shown in the picture below.
Flip stops are normally spaced at 125" apart, but can be set at customer specified intervals.

The compression fittings are enclosed inside the main frame and fit through the bottom of the trailer, keeping all air lines under the trailer itself, not just under the floor which could create difficulties for air line maintenance.

All rollers are heavy gauge, not just those at the rear of the trailer.

The main floor and top plates complete the installation. Total weight capacity of the completed system is 520 lbs / ft.
