Venturi suction device comes with water trap, particle filter and safety valve. It is made up of anodized aluminium, brass and poly-carbonate. It has been structured to offer a high vacuum source with a maximum pressure of 550 +25 mm Hg / 73 + 3 k Pa / 730 +30 m bar in regions where only dense air or oxygen are accessible. It consists of BS, NF, DIN and SS probes for air. It also comes with oxygen probes. With maximum vacuum pressure, the suction flow is 25 +2 L/min which puts a pressure of 0 - 100 k Pa (1,000 m bar). The device supplies a pressure of 3-8 bars with a maximum consumption of 40 L/min. It has been designed especially for the female users, supported by an inlet thread of 1/8" of Whit-worth Gas.
