FEATURES - The Model 20 Pneumatic High Capacity Pneumatic Flow Amplifier uses a pneumatic input signal to precisely control the output air pressure. Precise control of output air pressure using pneumatic input signals - Balanced air supply valves minimise the effects of unstable air supply pressures. Compensation Tube - Compensator tube compensates for downstream air pressure drop under flow conditions - Optional adjustable bypass needle valve allows adjustment for optimum dynamic response (1:1 only). Optional adjustable bypass needle valve allows adjustment for optimum dynamic response (1:1 ratio only). - Optional fixed negative bias allows operation with pneumatic equipment that cannot be adjusted to zero input air pressure. Optional fixed negative bias allows operation with pneumatic equipment that cannot be adjusted to zero incoming air pressure. - Separate control chamber isolates the diaphragm from the main flow to eliminate oscillation and noise. Separate control chamber isolates diaphragm from main flow to eliminate oscillation and noise - Machine construction allows for servicing without disassembly - Mounting brackets are available - Canadian Registered Number (CRN) certified for all territories and provinces Canadian Registered Number (CRN) certification for all territories and provinces Principle of Operation The Model 20 Supercharger is a high-flow, high-exhaust-capacity pneumatic device. This unit uses a force balancing system to control the supply of air. The unit uses a force balance system to control the movement of the supply and exhaust valves. The unit uses a force balance system to control the movement of the supply and exhaust valves. At the set point, the force created by the signal pressure applied to the top of the upper diaphragm at the top of the upper diaphragm will be balanced by the output pressure applied to the bottom of the lower diaphragm. pressure applied to the bottom of the lower diaphragm.
