Due to certain machining operations, the air in industrial environments can become saturated with polluting agents, such as dust and other motes, which are a danger to the health of the workers and do not comply to current standards. Savio S.r.l., constantly aware of this, and in the van in finding solutions to these problems, has studied and designed the EF/P electric filter that, being versatile and robust, is ideal for heavy duty uses. Widely used in chemical/foodstuff/metalwork industries, in pottery works, as well as on silos, mills, power hammers, mixers etc... it can be used where there are high temperatures and/or highly abrasive powders. 
The EF/P is particularly suitable for installation in heavy duty and continuous cycle plants; the cyclonic system, with the application of an internal counter-cone, lengthens the life of the sleeves and prevents the dust flow brushing against them at high speed . The thick, robust steel parts are constructed with drilled connecting flanges and, where necessary, assembly can take place on site , furthermore, the delivery inlet of the filtered air is adjustable and can be channelled, since it is provided with flanging. The filter can be supplied with or without fan, with or without hopper (if directly installed on specific containers, as breather filter) as requested by the customer. For routine maintenance operations, the EF/P have spacious inspection doors that allow easy access to the filtering section which is fitted with sleeves installed with bayonet connection, easily replaced when maintenance is required . The bayonet connection is very practical for sleeve disassembly since the release from the drum inside the filter is very quick and there are no straps or mechanical seals to be unscrewed.
The dusty air, sucked in by an electric filter, enters underneath the filtering sleeves through the cone, and after depositing the large dust particles by means of the cyclonic effect, it hits the external surface of the sleeves. The purified air passes through the filtering device inside the sleeve, enters into the exhaust and comes out through the filter outlet. The dry cleaning of the sleeve takes place in sequence by means of a compressed air jet coming out from the nozzles over the Venturi tubes. The compressed air jet in the Venturi tube brings in clean air coming from the other sleeves and creates a pressure wave that spreads along the entire length of the sleeve, shaking it. The dust on the external surface of the sleeve precipitates into the hopper and is extracted from there. The air passes through the sleeves at a velocity of 0.03 m/s and the rates of flow are from 710 m3/h up to 14000 m3/h, with a filtering surface ranging from 6.5 m2 to 66 m2. Remember, the Savio EF/P is available in many versions - Contact our Technical Office to find which version is most appropriate for your needs.
Some simple formulas are given below to help you choose the right EF/P S = Q / (V * 3600)
Key:
Therefore, knowing the designed rate of flow in m3/h and the pollutant, it is sufficient to apply the first formula and select the EF/P that has the same or a higher filtering surface .
