Industry-Specific Dust Filtration Solutions
PTH Viet Nam serves six major industrial sectors with application-engineered filter components. Each industry has distinct dust characteristics, temperature profiles and regulatory requirements.
Industries We Serve
Cement Plants
Challenge: Clinker dust, high temperature (180–260°C), SOₓ/NOₓ attack, abrasive dust on bags
Solution: PTFE/PPS bags with silicone-coated cages, Goyen RCAC pulse valves rated for 240°C continuous duty
36–48moBag life
<1,500PaΔP target
Steel & EAF
Challenge: EAF electric arc furnace: sudden temperature spikes, fine metal oxide dust, high air-to-cloth ratio demand
Solution: Nomex/Aramid or fiberglass bags, Aramid cage frames, high-flow pulse valves for short duty cycles
