FAQ

What is the pressure amplification ratio of the VBA40A-F04GN?
The VBA40A series has a pressure amplification ratio of 2. This means it can double the supplied air pressure up to its maximum output of 1.0 MPa. For example, an input of 0.5 MPa will result in an output of 1.0 MPa.

What do the ‘F04’ and ‘GN’ in the model number signify?
The ‘F04’ specifies the port size, which is G 1/2 (also known as BSPP 1/2 inch). The ‘GN’ indicates the unit is equipped with a round pressure gauge that includes a limit indicator, uses NBR seals, and has a standard adjustment knob.

Can this booster regulator be used with lubricated air?
No, the standard SMC VBA series is designed for use with non-lubricated compressed air. Using lubricated air can damage the internal components and seals. Always ensure your air supply is clean and dry.
