Product Overview
This is a Thomas 107 Series 107CDC20-898 diaphragm vacuum pump designed for 12VDC operation. The oil-less diaphragm design keeps the air path free from lubricants, making it suitable for clean vacuum applications. The 107 Series is widely integrated into portable equipment, mobile systems, and OEM assemblies where compact DC-powered performance is required. Depending on port configuration, the unit can be used to generate vacuum or light positive pressure.

Frequently Asked Questions
Has the pump been tested?
Yes. It was powered with 12VDC and tested using an external gauge, producing 21.5 inHg of vacuum.
Why does the installed gauge read lower?
The installed gauge reads 20 inHg while our external gauge measured 21.5 inHg. Variations may be due to gauge calibration or accuracy differences.
Is this an oil-lubricated pump?
No. It uses an oil-less diaphragm design, keeping the air path free of lubrication.
Can it generate pressure as well as vacuum?
Yes. With appropriate port configuration, the diaphragm mechanism can supply light positive pressure in addition to vacuum.
Compact and DC-powered, the Thomas 107 Series has long served in mobile and embedded systems. Verified under 12VDC, this unit is ready for its next integration.
