One the most sought after products that is manufactured entirely by SADAC is the modular mechanical shake dust filter unit. This modular concept unit is used for a wide range of applications for the effective capture and containment of fine dust particulate.
The filter housing is constructed from galvanized sheet metal in a series of modules with each module housing a multi pocket envelope filter bag and shaker attachment. The Dustmaster range is based on the number of modules and fan assembled to make up each size. This takes into account filter cloth type, filtration velocities, pressure drop over the filters, dust load and fan selection. In doing so SADAC has created a range of standard units ranging from 1500m³/hr to 11000m³/hr. Larger units comprising of nested modules and stand alone fan arrangements are available.
The DUSTMASTER design basis caters for an economical, robust, weather proof alternative for dust collection. It is favored in applications where clean dry compressed air is not available for filter cleaning and is supplied as a complete fully assembled and tested package unit. Contractors engaged in turn key installations take preference on this package as it simplifies selection and installation.
The filter bags are intermittently mechanically shaken by means of a shaker motor coupled to each filter by means of a shaker assembly. When the fan is switched off and comes to rest the timer controlled cleaning cycle is effected.
Collected filtered dust particulate is stored in collection drum sited below each module. The collection drum can be periodically removed or required to dispose of the collected particulate.
