The PresAir Trol adjustable vacuum switch is built for compatible systems that use a 1/8 inch MPT connection and require a 25 amp switch with an adjustable operating range of 135 to 300 inches of water. Adjustable vacuum switches are useful because they offer more flexibility when the control point needs to be matched closely to the system’s operating requirements.
This model is especially helpful when the original switch no longer reacts properly, falls out of range, or the application calls for an adjustable replacement rather than a fixed setting. The broader adjustment window can be valuable when dialing the system back into dependable operation.
It is a strong replacement option when vacuum-sensitive control needs to be restored with greater tuning flexibility.

- 1/8 inch MPT connection with 135 to 300 inches of water range
