Vacuum Flux recovery System, MVF is designed specifically for use with the roller and idler welder MRW series. When cycled, the system automatically cleans it's filter and dumps the dust; thus, "down time" for cleaning is eliminated. The filter is extra large and carries over 12 times blower capacity to insure very low head loss.

The 50/60 cycle motor is designed for several voltages to cover the wide range of conditions existing in the field. The pumping unit is equipped with a turbo blower that insures enough vacuum and reduces the noise level. A silencer is also attached at the top of the pumping unit.

Flux Flow Description

The vacuum flux recovery system on a MRW series consists of four units: pumping unit, a lower screening reservoir, upper flux tank and flux reservoir.

The units cycle begins when the upper tank empties into a flux hopper, the flux then goes to the welding heads where a portion are used. Used slag and unused flux pour down into the lower reservoir screen where the slag is seperated out and the flux returns to the reservoir. The pumping unit and reservoir vibration begin when the upper tank is empty. The flux is drawn from the reservoir into the upper tank. Once being full, the system automatically shuts down and the pumping unit cleans it's filter and dumps the dust. the upper tank then begins dumping flux and the cycle is complete.

The flux recovery system operates only when necessary. If the upper tank contains flux, the system will not start. Even when welding with both heads, the recirculating system needs to operate onlt 2 of every 12 minutes.
