- reduced filter area
- lower power consumption
- less space requirements
- savings on operating and installation costs
The system consists of following components
- stoner with air inlet hood
- fan with motor
- dust extractor
The design allows either arrangement as a space saving compact unit and if building space requires an open installation the fan extractor unit can be placed in remote location to the stoner. It is also possible to install the air recirculation system on an existing conv entional stoner.
Mode of Operation
The air is pulled through the stoner by the fan and pushed into the dust separator where the dust is skimmed off returning the clean air back to the stoner via the air inlet hood. Inside the dust separator, the air flow is looped around spirally. The dust and concentrated outer layer is pushed through an adjustable slot and must be sucked into a general exhaust system or filter. The air volume that is removed from the system is substituted by air around ihe stoner. The negative pressure in the system ensures that dust remains in the circuit.
The amount of air leaving the system can be controlled by adjusting the width of the slot of the dust separator and controlling air velocity in the aspiration duct.
