For reaching maximum filtration efficiency, cake release and durability, it is important to choose a right fabric media and its technical specifications. For this very reason, CDUNO products in accordance to the specifications given by the customers. CDUNO manufactures filter bags ranging from internal grooved Snap band, Integral plain snap band, Integral Rope cuff, Separate rope cuff, Collar type, Ring top, disc bottom and with single and double layer bottom cuff and variety of customized designs as per the requirement of the customers and/or in accordance with innovative & unique designs and concepts. With the Automation in producing Filter sleeves and top- bottom attachment, CDUNO ensures the uniformity and standard workmanship for its’s Filter Bags.
Some customers can face difficulty with exposure of bags to high temperature and look to CDUNO for reliable and error free operation of the filter. We provide perfect solutions, backed by our rich experience in this field.
At CDUNO, we fabricate quality filter bags for hot gas filtration at extremely corrosive environments effectively and efficiently. Our focus is on the correct selection of filter media, sewing thread and superior bag construction.
There is a greater risk of explosion caused by a spark during the process of filtration of flammable and explosive powders.
There is a chance of building up of static charges on the dust cake and filter media which may result in a severe explosion. To avoid these static charges and provide the filters with good antistatic properties, we mix proportionately conductive fiber elements while manufacturing nonwoven fabric.
A proper care must be taken to ensure that cage and support housing are properly earthed. Stainless steel fibers and carbon coated fiber blends are proven & most suitable ways to add during manufacturing filter media for anti-static & spark blocking properties.

Pulse Jet bags are cylindrical bags hanging vertically in a pulse jet dust collector bag house. The dust collects on the outer surface which is also called dust cake and is cleaned by a high velocity pulse of gas which is released in regular interval. In order for gas to sustain the regular operation of Filtering and cleaning it’s very important to select the right fabric media and design to achieve maximum efficiency. We offer Pulse jet bags in all major fabrics used industry wide making sure it’s suitable for the application and temperature.
CDUNO is producing Pulse jet bags mainly for all common industries. While producing any bag, CDUNO is focusing on every detail like Top fixing grove, bottom reinforcement, and bag tubing verticality. Other than this CDUNO ensures the overall bag fabric / Felt parameters throughout the length.
This in depth working makes the CDUNO bags performing extra-ordinarily in Process bag houses and helping to keep the bag house parameters as Standard.
Utility boilers, Cement, Carbon and Steel manufacturing units widely use woven glass media, which is suitable to sustain for continuous temperatures of (260°C) along with the capacity to take care of short duration of surge temperatures. To fulfill the demands of high temperature filtration and in case of poor performance of conventional needle felts like PPS and P-84 during higher oxygen and moisture levels in the gas stream, we craft exclusive woven fiber glass filter bags like pulse jet bags of different weight, construction and efficiency. Since, the glass acts as a heat sink, these perfectly carved bags can take care of hot particles without creating holes and easily withstand excess oxygen percentage in flue gases in a boiler application. These bags hold the ability to undergo most rigorous chemical environments and thus prove great value for money.
