Description
Gast DOA-P126-AA Diaphragm Vacuum Pump Andrew 40525A Dehydrator 115V 4A 60Hz
This is a Gast DOA-P126-AA oil-free diaphragm vacuum pump paired with an Andrew 40525A automatic desiccant dehydrator head. The combination functions as a self-contained dehydrator/compressor unit, drawing in ambient air, drying it through a desiccant stage, and delivering low-pressure dry air — a configuration commonly used in telecom and RF transmission systems to pressurize and dehydrate waveguide runs and antenna feedlines. The motor is a single-phase 115V unit manufactured by Gast MFG Corp in Benton Harbor, Michigan.

Applications
The Gast DOA-P126-AA is an oil-free diaphragm pump, a compact and reliable pump type widely used in applications requiring clean, dry air or a modest vacuum without the maintenance demands of oil-sealed designs. The Andrew 40525A dehydrator head is a component from Andrew Corporation (now part of CommScope), a major manufacturer of RF coaxial cable and antenna systems. Dehydrator units of this type are used in telecom and broadcast infrastructure to keep waveguides, rigid coaxial transmission lines, and pressurized antenna feedlines dry — preventing moisture ingress that would degrade RF performance or cause arcing. This style of compact dehydrator/pump combination is also used in laboratory settings, environmental chambers, small-scale pneumatic systems, and anywhere a source of clean, low-pressure dry air is needed. The oil-free diaphragm design makes it suitable for applications where oil contamination of the air stream is unacceptable.
This Gast DOA-P126-AA Diaphragm Vacuum Pump with Andrew 40525A Dehydrator head has been inspected and tested at our facility. It powered up on 115 VAC and produced a vacuum — it tests good. The unit is in good used condition overall with normal wear to the painted cast housing, consistent with prior service use. Note: the power cord has been cut short and will need to be replaced or rewired before use. Please view our photo set and contact us if you have any questions.
