Laboratory aspiratorLA-DUAL The LA-DUAL laboratory aspirator is designed for separation of mixtures in two or three fractions according to the product's aerodynamic characteristics in an air stream It is very well suited for laboratory use as well as for small scale production. The aspirator can be delivered in two different configurations for batch or for continuous flow operation. In standard construction, the LA-DUAL machines are delivered with the following features. The machine is fitted with inlet hopper and vibratory feeder with start/stop and potentiometer. The double aspiration chamber has manually operated distribution valve. The machine is complete with integral fan with 0.27 kW, 240 V, 50 Hz, air filter, and dust container. Triac control for airflow regulation is also included. In construction for batch operation,the machine has closing valve below the aspiration chambers and manually operated air valve and false air valve. In construction for continuous flow operation, the machine has larger inlet hopper and two rotary valves (each with a 6 W motor) in both aspiration chambers instead of closing valve. The machine has collecting bins for light and heavy fractions and is mounted on a convenient worktable. The machine is of steel construction with a big plexiglass window on one side. Special features: ♦ Servo motor with potentiometer for regulation valves ♦ Heavy duty fan ♦ Autotransformer and switch for 110 V, 60 Hz Please contact us for detailed information or meet us at www.westrup.com
