Product characteristics of automotive filters
The characteristics of the filter are based on the specification of the original equipment manufacturers:
permeability, corrugation depth, bursting strength, pore size, volatile content, resin content and width
and height. All the three filters are required for proper functioning of internal combustion engine. The
technical textile used in the filters is polyester and cellulose non-woven fabric of around 120-150
GSM.
Market Dynamics and key growth drivers
The primary growth driver for automobile filters is the automotive industry (including the
replacement market).
The key end users for industrial filters are Cement, Pharmaceuticals, Fertilizer, Food Processing,
Power and Engineering sectors. The demand of filter equipments and filter media is driven by the
performance of these sectors. The filter media has a higher proportion of replacement demand
compared to the filtration equipments. The increasing emphasis on pollution control and occupational
health augur well for the industry.
Key manufacturer of automotive filtration medium
There are only few organised big players in the filter fabrics industry. However, there are large
number of small companies which manufacture filter fabric from viscose, polypropylene and
polyester. The major players in the automotive filter market are Purolator India Limited, John Fowler

plant at Khandsa, is the largest of its kind in India. The unit produces close to 3600 MT of filter paper.
The unit was setup primarily to replace imports and promote the indigenous manufacture of filter
paper.
