Teledyne 701 Manuel D’Utilisation

OPERATION 

Teledyne API Model 701 Zero Air Generator 

5-6 

01671H (DCN6051) 

The compressor is a single-cylinder oscillating piston type driven by a split capacitor AC 
motor. The compressor is dry; that is, there are no lubricants which can contaminate the 
compressed air. The pistons are sealed by flexible TFE piston rings, and after a short 
run-in period to seat the rings, should last for years. There are no diaphragms. 

The compressor is mounted on a sub-plate which is supported on four tuned vibration 
isolators. During shipment, the sub-plated is bolted firmly to the chassis.  

Be sure that you have removed the shipping screws before 
you start the M701. 

 

The cooling coil consists of several turns of copper tubing coiled to form a cylinder 
through which the cooling fan blows outside air. 

The water trap is a coalescing type. Supersaturated air enters the trap and is rapidly 
swirled causing the water droplets to deposit on a membrane where the drops coalesce 
and gather in a puddle at the bottom of the filter bowl. 

Accumulated water is drained from the filter through a stainless steel solenoid-operated 
valve. The valve is sequenced by the controller and is open for approximately 2 
seconds every 5 minutes. 

Do not forget that the water/air spray leaving the rear panel DRAIN 
fitting spurts at a high velocity and should be appropriately 
conducted away from any sensitive components.  

 

The operation cycle has been preset at the factory and is not adjustable.
