AS ONE Vacuman pressure reduction/pressurization pump

This manual air pump for non-viscous liquids can be switched between vacuum (suction) and pressure (discharge). The body is made of polyvinyl chloride (PVC) and is connected to a thick, soft tube with an inner diameter of 6 mm. When decompressing, be sure to first collect the sampled water in a bottle or similar to prevent it from entering the pump cylinder. With a few strokes, the pressure can be reduced to 85 kPa and the pressure can be increased to 200 kPa. The pressure can be released by pushing up the lever under the gauge, so there is no need to remove the connecting tube to release it. To switch between vacuum and pressure, manually turn the cock under the gauge to the VACUUM (vacuum) or PRESSURE (pressure) direction. Size includes the gauge.
