INER-ST Inertia filters

Inertia filters SagiCofim INER-ST Inertial separation is an excellent pre-filtration system, particularly suitable in environments with high dust concentration as desert areas, mines, steel and foundry factories, cement industries. This filtration system is based on the principle of conservation of kinetic energy by the airborne dust particles. Thanks to a series of quick changes in direction, while the clean airflow is being employed in the process, through inertia the particles continue moving in a straight line till they eventually reach the unloading hopper. There, thanks to a small...

Inertia filters SagiCofim INER-ST How an inertia cell works An inertia cell is made up of a pair of V-arranged panels, on whose surface are pressed slots through which the air flow makes the quick changes of direction described above. A central straightening vane is installed to reduce the air turbulences. The two V’s converge at the bottom of the filter leaving an opening which is proportional to the air inlet opening, so to maintain the air flow speed constant inside the filter. Being self-cleaning, inertia filters have unlimited service life. Material of Construction Inertia filters are...

Inertia filters Supply configuration Inertia filters can be housed in a galvanized steel housing, properly stiffened and painted with specific coating suitable for aggressive environment, consisting in a primer coat and a final enamel coat. The standard steel thickness is 2 mm., but different thicknesses are available. For critical applications, special paints or stainless steel can be used. The air intake can be provided with an air inlet grid (insect screen) and duct connection flange. A maintenance door, support legs, lifting lugs, flanged connection to the main fan complete the supply. The...

Inertia filters SagiCofim INER-ST Options Usually no instruments are required for inertia filters operation. The following devices can be supplied on request: High Pressure Alarm Differential pressure switches can be supplied to provide alarm in case of pressure loss beyond normal limits. The indication can be local or remote. Manometer Differential manometers can be provided to monitor the pressure drop of the installation. Control panel / Junction box The bleed fan is usually supplied unwired and shall be connected in situ. On request, it is possible to provide a local control panel or a...

Inertia filters SagiCofim INER-ST Maintenance instructions The inertial filter is a self-cleaning device with no consumable parts, therefore it requires no ordinary maintenance. However, a periodic check of the unit is recommended: remove any foreign body which may obstruct the filter blades with a metal brush and/or compressed air. Then check the dust discharge duct and remove any deposit. Beat the vertical ducts of the inertial filters by means of a wooden mallet in order to remove any residue inside them. Check accurately the proper conditions of inlets which may be obstructed, that the...
