Gast ROA-P111

This is a used Gast ROA-P111 oil-less diaphragm vacuum and pressure pump, a model built for applications requiring clean, contamination-free air handling. The unit has prior operating history and carries some cosmetic wear, but it remains in working condition and ready to be redeployed. Its oil-less diaphragm design eliminates the need for lubrication, which is a key advantage in laboratory and medical settings where air purity matters. The ROA-P111 is commonly used in analytical instruments, medical devices, and laboratory equipment that require both vacuum and low-pressure air delivery from a single compact unit. Its dual-function capability makes it versatile for OEM integration as well as standalone bench applications such as filtration, sample handling, and fluid aspiration. The pump's quiet operation and minimal maintenance requirements have made this series a longstanding favorite among equipment builders. Offered as a used unit, this pump provides a cost-effective alternative to purchasing new, while still delivering the performance characteristics that made the ROA-P111 series a trusted choice in its original applications. It is well suited for labs, service technicians, and OEM integrators looking for a reliable, clean-running vacuum and pressure source.
