Brief introduction: Elveflow VAN vacuum generator is used for accurate and rapid pressure generation and vacuum generation, providing pressure source for fluid flow in micro-flow control system. The VAN system provides two output interfaces, one for positive pressure and one for negative pressure, and one for simultaneous output. Compared with similar products on the market, VAN air pressure generator is more compact in structure, smaller in size and noise, and more suitable for scientific research laboratories. The VAN pressure generator provides pressure from -0.7 to 1.9bar. Product specification: Configuration: two separate brushless motor driven air pumps Size: 24cm x 13cm x 13cm Maximum traffic: 4.3l/min (for each channel) Weight: 1.8 kg Working voltage: 24V 53 db noise: Pressure control range: -0.7 to 1.9bar
