FILTER BAGS AND BAGHOUSE SOLUTIONS
Science of Particle Air Separation
Solid air Filtration in high temperature heavy lies on a multifold parameter relating to system and media. The effectiveness of bag filters as a filtration mechanism for a PM2.5 as per US EPA ETV standards is what controls the emissions and can be engineered towards emission norms.
Supertech Fabrics specialises in filtration and separation media technology of using dust bags principle. Our offerings are a range of filter bags for various dust separation systems in a wide assortment of fabrics, finishes, laminated membranes and sizes along with Cage support systems.
Changes to the gas stream chemistry, moisture or hydrocarbons and/ or high temperature spikes as well as operation conditions need to be considered to maximise filter life and performance.
Filter Media Engineering
Effectiveness of Separation technology is controlled mainly by the media. Supertech Fabrics is an original materials manufacturer of such media, specialising in fiberglass and ePTFE membrane technologies.
We customise filtration fabric media to maximise filtration efficiency, dust cake release properties and durability.

Pulse Jet System Dust Bags
Most common these days, pulse jet systems use an outside in air flow approach with a higher air to cloth ratio. Designed as a compact system, it uses cage support and pulsing technology for dust cake removal.

Reverse Air System Dust Bags
Reverse air approach, as the same suggests, is the opposite of PJBH, where the air flows inside out. The cake formation is from inside and is removed by gravity. Unlike PJBH, there is not pulsing, the air to cloth ratio is very low, and therefore some would treat this system from a filtration stand point as more effective and simpler. Therefore it is very popular as a solution where material recovery is involved. It is more space taking though.
RABH utilises a lower GSM in both woven and non-woven, with ePTFE membrane from the inside.

Filter Cages
Our Filter cages are manufactured by a high grade automatic welding line that keeps the joins smooth and not sharp, one of the prerequisites of sustained bag life. Manufacturing has a capacity to handle materials like Mild steel, Galvanized steel, and Stainless steel.
Cages are fabricated from
- Galvanized carbon Steel
- 304 Stainless Steel
- 316 Stainless Steel
- Mild Steel
Split Designs
- Ring to Ring Locking
- Twist Lock
- Groove Split Lock
- Slide Lock
Types of cages

Application
CEMENT INDUSTRY
As the industry’s backbone to pollution control and material recovery, filter bags have a wide range of applications in the plant. From Raw mill, to cement mill, to coal mills. Typically a combination of both RABH and PJBH, with various flue gas conditions.
FERRO ALLOY
STEEL MILLS
ALUMINUM FURNACES
CARBON BLACK
Like cement, Carbon block industry also depends highly on filter bags and its efficiency. Typically found with both RABH and PJBH with a very fine particle size.
MSW INCINERATORS
COAL FIRED POWER PLANTS
DRYERS
BOILERS / HIGH TEMPERATURE DEDUSTING
Utility boilers in Chemical/Pharmaceutical/ textile/ paper/ polymer/ and many other industry types are utilises a vast range of fuels including solid and gas. emissions from such demanding flue gas compositions are met with filter bags.
