Hybrid Filter
Clair offers Hybrid Bag filters which can be applied in various industries across different applications. Hybrid filter is a combination of Electrostatic Precipitator (ESP) and Bag Filter. The ESP is at the inlet, where the particles are changed and collected, and the subsequent fields are bag filter used for removing the finer particles.
The concept of Hybrid filter was introduced with the primary intent of serving as a retrofit solution for existing ESP’s to meet the stringent emission norms. The existing casing of the ESP is used and converted to a Hybrid Filter thereby substantially reducing the cost and down time of the retrofit.
The dust laden gases first enter in to the ESP field and the majority of the dust is collected in this section. The fine dust particles are ‘electro-statically charged’ in this field section and then move to the ‘bag house’ section.
These ‘charged’ dust particles moves over to the filter bag and form a ‘porous cake’ over the surface and are filtered out from the gas stream. The dust layer forms a porous cake mainly due to the charged dust particles. Such ‘porosity’ of the dust cake layer helps to achieve a lower differential pressure and this also prevents any major re-entrainment during bag cleaning operation.
Advantages of Hybrid Filter:
Secondary Fume Extraction Systems (SFES) in:
A boiler or Steam Generator (prime mover) is an integral device in a fossil fuel power plant used to produce steam by applying heat energy to water. A boiler incorporates a furnace in order to burn the fossil fuel (coal, gas, waste etc.) and generate heat which is transferred to water to make steam. Depending on the type of boiler and the flue gas composition, the Process Bag Filter is designed.
Process Filters form part of Fume & Dust Extraction System for Induction Furnace. It is required to control the resultant air pollution control by extraction fumes through hood. The extracted fumes and gases (often flame laden) are taken away to ID Fans, Air Pollution treatment and Control systems.
Zero Effluent Discharge has been a concern for clean environment and the Pollution Control Board has mandated distilleries to achieve the zero discharge. Process Bag filters are used extensively to control fumes / gases after the incineration of spent wash.
Our indigenously evolved cleaning technology for long bag filters means tighter compliance with regulations while also offering the flexibility to retrofit or upgrade to minimize on cost without compromising on performance.

Retrofit/Upgradation
Our Fabric filters high efficiency equipment that offers high removal of finer particulates. In designing a fabric filter unit, main consideration would be the type of filter cloth, method of cleaning and pressure drop. However, process parameters like particulate characteristics, carrier gas characteristics and process factors form the basis in selection of fabric filters. The fabric filter systems are frequently referred to as bag houses or bag filters, since the fabric is usually configured in cylindrical “bags”.
