FAQ

What is the function of the brass fitting with the wingnut?

The brass fitting is a manual drain cock. It is used to periodically remove any moisture or contaminants that may have collected in the regulator’s dripwell, protecting downstream components.

Can this regulator be panel mounted?

Yes, the design of the Model 91-HF allows for panel mounting. The included hardware in the package can be used for this purpose, providing a secure and clean installation on a control panel.

What is the recommended maintenance for the Model 91-HF to ensure longevity?

For optimal performance, it is recommended to regularly use the manual drain to clear moisture. Additionally, ensure the supply air is clean and dry by using an upstream filter (typically 5-micron) to prevent internal contamination of the regulator’s diaphragm and seat.
