Designed for the world's polluting processes.
30–35% of turnover exported. Installations in 40+ countries. Our filter media is engineered to survive the dust loads, chemistries and temperatures of the world's most demanding emitters.
Kilns, raw mills, clinker coolers, coal mills, packers
High-temperature, abrasive, alkaline conditions. P-84, PPS and meta-aramid bags are standard, with ultra-microfibre surface layers for the tightest emission targets and anti-static felts for coal mills.
Sinter, BF gas cleaning, EAF dedusting, BOF
Heavy dust load, oily fume, occasional sparks. Aramid and PPS media with anti-static and FR finishes, engineered for the realities of melt shops.
Alumina calciners, smelter potline and casthouse fume
Fine, abrasive alumina and fluoride-bearing fume. Felts specified by fibre and decitex for fine-particle capture and stable pressure drop through long campaigns.
Ferro-silicon and submerged-arc furnace off-gas
Very fine silica fume at high volume. Ultra-microfibre surface filtration captures the fine fraction at the felt surface, so the cake releases and the air keeps moving.
Coal-fired boilers, ash handling, FGD
PPS and fibreglass media engineered for acidic conditions and fly-ash abrasion, PTFE-impregnated where acid resistance demands it. Reverse-air installations sized for 25 m bag lengths.
Combustion gas cleaning, char filtration
Sticky char, high moisture, variable feedstock chemistry. Lofted needle felts with hydrophobic and oleophobic finishes for stable ΔP.
Copper, zinc, lead
Aggressive chemistry and condensation risk. Fibreglass and high-temperature felts, with finishes selected for each smelter chemistry.
Shakeout, sand reclamation, melting cupolas
Oily, hot, ferrous-rich dust. Aramid needle felts with microfibre surface layers for surface filtration and easy cake release.
Drum & batch plants
Cyclic heat, sticky residue. Meta-aramid bags with anti-stick finishes, sized for the road-construction service cycle.
Fertiliser, milling, sawmills & MDF, tobacco
Lofted polyester and acrylic felts for gentle low-pressure systems, engineered around food-grade and combustible-dust safety considerations.
From Bangalore to 40+ countries.
Around a third of our turnover is exported: across the Middle East (UAE, Saudi Arabia, Bahrain, Turkey), Bangladesh and Southeast Asia (Thailand, Malaysia, Indonesia, Vietnam), with Africa a growing focus.
We pioneered the use of microfibers in India to attain very low emission levels, for customers who are generally polluting industries.
