The BD-05TVB-S.1 uses a brushless DC motor to drive a reciprocating diaphragm, creating clean, oil-free airflow or vacuum. Gas enters during suction and exits under pressure through check valves—ensuring stable, contamination-free performance.
With a maximum flow rate of 5.5 L/min, vacuum suction up to –70 kPa, and positive pressure up to 1.5 Bar, this mini compressor pump offers stable performance for both vacuum and pressure-based systems.
Its compact structure (only 148 g) and reliable output make it ideal for applications such as negative pressure wound therapy (NPWT), vacuum gas sampling, and laboratory automation. Built with corrosion-resistant materials and optimized for long service life, it is a preferred solution for engineers integrating into space-constrained systems requiring high precision.
