Model 370 Mini Air Pump - compact electric micro vacuum booster motor available in 3.7 V, 6 V, and 12 V versions. Designed for use with beauty devices, equipment used in medical settings, and as an assist unit for breast pump systems, this pump delivers reliable vacuum and pressure performance in a small footprint. Key benefits and why you need it - Compact and versatile: small form factor and consistent function across voltage options make it easy to integrate into handheld or benchtop devices. - Strong vacuum and pressure range: covers a wide working range from vacuum to positive pressure so it can support multiple device functions. - Stable performance: proven cycle durability and controlled noise level make it suitable for repeated, intermittent operation. - Simple power compatibility: available in common DC voltages with clear voltage ranges for straightforward power supply selection. Features and specifications - Model: 370 Mini Air Pump. - Available nominal voltages: 3.7 V, 6 V, 12 V. For the 6 V model the operating range is DC 4.8 V to 7.2 V. For the 12 V model the operating range is DC 10.8 V to 13.2 V. - Pressure range: -450 mmHg to 900 mmHg, equivalent to about -60 kPa to 120 kPa. - Flow rate: at least 22.8 liters per minute. - Noise: measured under standard test conditions with pump mounted on a 5 cm sponge and microphone at 30 cm; under nominal voltage and inflation pressure from 0 to 420 mmHg the sound level is below 60 dB. - Durability: tested for 30,000 cycles using a 10 second on, 5 second off cycle with output power variation within 15 percent. Continuous 24 hour runtime typically yields 400 to 500 hours of service; intermittent operation extends service life. - Operating fluid: air. - Operating temperature: 0 C to 55 C. Performance and electrical notes - Voltage selection: the same pump
