OPERATION Teledyne API Model 701 Zero Air Generator
5-6 01671H (DCN6051)
5.2 Compressor 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.
CAUTION
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.
5.4 Water Trap 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.
5.5 Water Drain Valve 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.
CAUTION
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.
