These suction regulators from BeaconMedaes are made with cast metal backplates and are used with encased gauges to protect the unit and to get all sorts of stresses under control. This makes it so the plastic regulator will not be likely to crack and break apart to where it would have to be replaced. This is also made with a bright appearance where the unit is being adjusted to stay on duty and not on a bench. The regulators around here are modular so the unit can work quickly and with standard tools without any serious repair issues needed. This is also made to work with a sensible control setting and a readout that is very easy for anyone to manage.
