The Dynaflow Fume Scrubber is a compact unit and has a high performance rating compared to its overall size. While designed principally to handle perchloric acid fumes, it can be adapted to suit many other fume scrubbing applications.

The unit is normally supplied with a water wash supple from a packaged recirculating system located below the fume cupboard. The recycling plant, for use with the scrubber unit, consists of a recycling tank, pump assembly and linking pipework to form an enclosed system. Effluent levels can be checked before the discharge is drained and the water in the tank can be dosed with the appropriate neutralizing agent.

The unit is designed to fit directly to the flanged outlets of the Dynaflow range of aerodynamic fume cupboards, although in some circumstances, it can be fitted up to one metre above the outlet without the necessity of sprays in the duct.

The unit is moulded in one piece from chemical grade glass-reinforced fire retarded plastic. It incorporates two patented filter pads in removable frames, together with a spray jet section all internally mounted. Both pads and spray bar can be viewed through a clear PVC inspection panel.

The one piece moulded spillage tray contains two mounting plinths for the recycling tank and incorporates a reinforced locating pad for resiliently mounting the pump unit. This tray has a surround to contain any accidental spillage and is designed to fit inside the Dynaflow Fume Cupboard support unit.

The tank and removable lid is manufactured from chemical grade GRP. The tank is fitted with a water supply inlet and plastic ball float value. Incorporated in the side of the tank is a sight glass to enable a constant check to be kept on the fluid level, without removing the lid. A connection for the mist eliminator drain return pipe is provided in the upper part of the tank which also has an overflow pipe connected to the main drainage pipework.

The pump, resiliently mounted on the above tray, is a leakproof magnetic driven, polypropylene centrifugal chemical pump. It is coupled to a totally enclosed 240 volt motor and is equipped with thermal overload protection. Its ceramic rotating spindle is supported at both ends by TFE.

All pipework, valves, etc, are pre-plumbed between recycle tank and pump: pump to spray section of the fume scrubber; drain from scrubber to recycle tank; and overflow from the tank to drain valve connection. It is disassembled and left ready for easy reassembly on site.
