Fiber Mist Eliminator
Fiber Bed Mist Eliminators • Candle Mist Eliminator Elements • Sub-Micron Aerosol Removal
ECOGRACE high-efficiency fiber bed mist eliminators achieve 99.9% removal of sub-micron liquid aerosols down to 0.3 μm. Also known as candle mist eliminators or acid mist filters, these systems are purpose-engineered for sulfuric acid mist, oil mist, chemical aerosol, and corrosive fume applications — exceeding EPA emission standards with low pressure drop across the fiber pack.

Fiber Mist Eliminator Product Range
ECOGRACE manufactures three configurations of fiber bed mist eliminators to match your specific process conditions, space constraints, and emission targets.
How Does a Fiber Bed Mist Eliminator Work?
Fiber mist eliminators use the Brownian diffusion capture mechanism — fundamentally different from inertial separators — enabling removal of sub-micron aerosols that wire mesh and vane demisters cannot capture.
Gas Entry
Mist-laden gas enters the fiber mist eliminator vessel and flows toward tightly packed fiber bed elements through a uniform distribution space.
Brownian Capture
Sub-micron droplets undergo Brownian diffusion within the fiber pack, colliding with densely arranged fibers (2–25 μm diameter). Particles as small as 0.3 μm are efficiently captured.
Coalescence
Captured droplets coalesce on fiber surfaces into progressively larger drops. Surface tension and capillary forces move liquid through the fiber bed toward the drainage face.
Clean Gas Out
Coalesced liquid drains by gravity to the vessel sump. Clean gas exits with <10 mg/Nm³ particulate, meeting the strictest EPA and environmental standards.
Fiber Mist Eliminator vs Wire Mesh vs Vane Type
Choosing the right mist eliminator filter depends on particle size, efficiency requirements, and process conditions. The fiber bed is the only technology capable of sub-micron aerosol removal.

Frequently Asked Questions
How does a fiber bed mist eliminator work?
A fiber bed mist eliminator captures sub-micron liquid droplets through three simultaneous mechanisms: Brownian diffusion (primary for particles <1 μm), direct interception, and inertial impaction. Mist-laden gas passes through tightly packed fiber beds (fiber diameter 2–25 μm) at low velocity (0.05–0.25 m/s). Fine droplets undergo random Brownian motion, collide with fiber surfaces, coalesce into larger drops, and drain by gravity. This achieves 99.9%+ removal efficiency for particles as small as 0.3 microns — far beyond the capability of wire mesh or vane type separators.
What is the difference between fiber mist eliminator and wire mesh demister?
Wire mesh demisters rely on inertial impaction and remove droplets larger than 10 μm at 98–99% efficiency. They cannot capture sub-micron aerosols. Fiber bed mist eliminators use Brownian diffusion to capture particles down to 0.3 μm at 99.9%+ efficiency. If your application involves acid mist, chemical aerosol, or emissions below 10 mg/Nm³, a fiber mist eliminator is required. Wire mesh is suitable only for coarse droplet removal in general distillation.
What materials are available for fiber mist eliminators?
Fiber materials: Borosilicate glass fiber (most common, up to 260°C), PTFE fiber (highest chemical resistance, for HF, chlorine, strong oxidizers), polypropylene fiber (economical, up to 90°C), and composite fibers. Housing materials: FRP (most popular for acid service), stainless steel 316L, Hastelloy C-276, duplex steel, and polypropylene. ECOGRACE provides complete corrosion-resistant mist eliminator solutions for the most aggressive environments.
How to select the right mist eliminator for my application?
Selection depends on four key factors: 1) Particle size — fiber bed for sub-micron (<3 μm), wire mesh for >10 μm, vane for >20 μm; 2) Gas flow rate and velocity; 3) Chemical compatibility; 4) Required outlet emission — if <10 mg/Nm³ is needed, fiber bed is mandatory. Send ECOGRACE your process data sheet and our engineering team provides free mist eliminator sizing calculation and recommendation within 24 hours.
How much does a fiber mist eliminator cost?
Fiber mist eliminator prices range from USD 2,500 for individual replacement candle elements to USD 85,000+ for complete large-diameter vessel systems. Key cost drivers: gas flow rate, fiber material (PTFE costs 3–5x glass fiber), housing material, and design pressure. As a direct fiber mist eliminator manufacturer, ECOGRACE offers factory-direct pricing 30–50% below Western OEM brands for equivalent quality.
