● Features: 1, suitable for harsh temperature environments, can be -30 ℃ ~ +60 ℃ environment of continuous operation at full load around the clock. 2, the inlet can be used for vacuum, gas sampling, etc.; pollution-free transmission, maintenance-free; may be installed in any direction. ● Detailed parameters: a, type? No.: VXA3203 voltage: 12 V DC / 24 V DC load current: <420 mA (12 V DC); <240 m A (24 V DC) Peak Flow: 3 L / min average flow : 2 L / min vacuum (absolute pressure): ≈ 69 kPa negative pressure (relative to vacuum): 32 kPa Second, model: VXA4505 Voltage: 12 V DC / 24 V DC Load current: <480 m A (12 V DC); <260 m A (24 V DC) Peak flow rate: 5 L / min average flow rate: 2.8 L / min (12 V DC); 3.2 L / min (24 V DC) vacuum (absolute pressure): ≈ 56 kPa negative pressure (relative vacuum): 45 kPa Note: All parameters are on the table in a standard atmospheric pressure, 20 ℃ time value. Unless otherwise noted, at 20 ℃, standard atmospheric pressure load flow we all referred traffic. ● Optional: 1, pump suction side can take large loads, or even completely blocked, are working properly, the pump will not be damaged. 2, the pump must be unobstructed discharge end of the exhaust pipe shall not have any damping elements! 3 Recommendation: 24V preferred products, the same price, better quality. 4, all specifications are using the DC power supply; ordering please indicate working voltage, such as, VXA3203-24V. 5, Weight: about 420 g 6, for other voltages, the flow of product specifications, you can contact customization. ● Instructions for use: 1, the pump working medium: gas pumped must be non-corrosive, non-oily, non-ice and other solid foreign objects. Was pumping gas allowable temperature range: -30 ℃ ~ +60 ℃ 2, the pump working environment: the pump should not be in the outdoor sun, shall be clean and free of corrosive environment Operating temperature: -30 ℃ ~ +60 ℃ (no knot Lu) Relative humidity: ≤ 75% 3, pump storage environment: The pump must be stored in clean, dry non-corrosive environment Storage temperature: -30 ℃ ~ +60 ℃ (no condensation) Storage Relative Humidity: ≤ 75 % ● Note: 1, foreign body may not fall into the gas nozzle, otherwise it will damage the micro-pump. 2, the exhaust pipe must ensure smooth, otherwise the pump will be damaged. 3, the product does not have proof performance, can not be used in explosive environments! 4, when the extraction of harmful gases, the customer must re-seal the pump to ensure safe!
