Low Noise 12V Vacuum Pump Compact Size

This WP370B mini vacuum air pump features a highly compact form factor — just 80 mm (3.15 in) long — and is moulded from impact-resistant ABS plastic for longevity in active use. It runs on standard DC power, with a nominal voltage of 12.0V and full functionality maintained across 9.6V–14.4V. Under load, it consumes 350mA and delivers an air flow of 0.5–1.5 L/min when generating vacuum, and 1.1–1.3 L/min when moving water-based media. Its maximum inflation pressure is capped at 60 kPa, prioritising control and safety over aggressive output. Operating temperature spans -20°C to +60°C, and acoustic output remains at a measured 60 dB — quiet enough for close-proximity use. Its stability makes it appropriate for calibrated tasks: collecting gaseous samples without turbulence, evacuating small chambers prior to testing, inflating soft elastomeric components, or supporting low-vacuum stages in educational physics demonstrations. The consistent output reduces variability in repeated procedures — a key advantage over entry-level pumps prone to drift. Designed for universal integration, it connects directly to any regulated DC source. No mounting hardware is included, but its slim profile allows screwless clamping, adhesive bonding or custom bracketing — giving users full flexibility whether building a portable medical aid, upgrading a home vacuum sealer or automating a chemistry rig.
