1PCS Vacuum Pump DC 12V Negative Pressure Air Suction Pump 5L/min 65-120kpa

<p><strong>Features:<br></strong><br>- and <br>- Made of material, <br>- Vacuum pump DC 12V negative pressure air pump low noise 5L/min 65-120kpa with bracket<br>- The pump is driven by a DC motor, which drives the internal mechanical eccentric movement, and the eccentric movement drives the internal reciprocating movement of the diaphragm. In this way, the constant-volume air in the pump chamber is compressed (the compression suction port is closed, and the exhaust port forms a slightly open positive pressure), and stretched (the compression exhaust port is closed, and the negative pressure suction port is opened). The difference in pressure (suction) as gas enters the pump chamber and exits through the discharge port.<br>- Vacuum pumps are mainly used in electrical products, industrial products, vacuum preservation machines, automobile exhaust reforming equipment,&nbsp;equipment, gas analysis and sampling, instrumentation and other fields. Completely maintenance-free, no oil pump, no pollution to the conveying medium, and can work continuously for a long time.<br>- Small size, stable and reliable, hand-held pump suction instrument, low noise, low power consumption. Especially suitable for occasions with high negative environmental requirements.<br><br><strong>Specification:</strong><br><br>- Working voltage: DC9V~14V<br>- Rated voltage: DC 12V<br>- Rated current: 500mA<br>- Rated power: 6W<br>- Suction: 5L/min<br>- Vacuum degree: 65kpa<br>- Maximum pressure: 120kpa<br>- Noise: &lt;60db<br>- Applicable to: 4.5-6mm pipe, the largest part of the outer diameter is 6.5mm<br>- Material: engineering plastic + aluminum<br>- Size: about 83*71*60mm<br><br><strong>Package includes:</strong><br><br>1*vacuum pump<br><br><strong>Notes:</strong><br><br>1. Due to various factors such as display brightness and light brightness, the actual color of the product may be slightly different from the website picture.<br>2.
