What is a fiber bed mist eliminator?

A fiber bed mist eliminator is an industrial gas-liquid separation device that removes submicron liquid droplets (0.1–3μm) from gas streams using a packed bed of fine PTFE or glass fibers. It achieves >99.96% mist removal efficiency through inertial impaction, direct interception, and Brownian diffusion.

What is the difference between a fiber bed and a wire mesh demister?

Wire mesh demisters capture coarse droplets larger than 3–5μm by inertial impaction. Fiber bed mist eliminators capture submicron droplets (0.1–3μm) with >99.96% efficiency, making them ideal for sulfuric acid, chlor-alkali, and corrosive fine acid mist applications.

What materials are used for sulfuric acid service?

For sulfuric acid mist elimination, PTFE (polytetrafluoroethylene) fibers are used for maximum chemical resistance. Shell materials typically include PP, FRP, or alloy steel with PTFE lining for high-temperature concentrated acid.

Evaluate Filtearth Fiber Bed Mist Eliminator Performance

Requesting a fiber bed mist eliminator sample from Filtearth is a straightforward process designed to help you evaluate performance before committing to a full project.
At Filtearth, we understand that selecting the right fiber bed mist eliminator is a critical decision for your process reliability and emission control.
Unlike standard filtration products, fiber bed mist eliminators are highly engineered components designed according to specific operating conditions, including:
✅️Gas composition
✅️Operating temperature
✅️Gas flow rate
✅️Mist concentration
✅️Droplet size distribution
✅️Corrosion requirements
✅️Equipment dimensions
Therefore, we do not provide free samples as a standard service. Each sample requires material selection, engineering review, manufacturing, and quality inspection to ensure it represents the actual operating requirements of your application.

How Our Sample Evaluation Works

Step 1 — Submit Your Application Details

Please provide the following information:
✓ Process industry
✓ Gas composition
✓ Operating temperature
✓ Gas flow rate
✓ Existing equipment dimensions
✓ Required efficiency or emission target
✓ Installation drawings (if available)
Our engineering team will review your application and recommend the most suitable solution.

Step 2 — Technical Proposal & Sample Recommendation

Based on your operating conditions, we will determine:
·Suitable fiber material (Glass Fiber / PTFE / PP / Customized)
·Fiber bed thickness
·Packing density
·Element dimensions
·Housing material
·Expected pressure drop and efficiency
If a sample evaluation is technically appropriate, we will provide a detailed proposal including sample specifications and commercial terms.

Step 3 — Sample Manufacturing & Testing

Each evaluation unit is manufactured according to approved technical specifications and can be supplied with supporting documents, including:
✓ Material certificates
✓ Dimensional inspection report
✓ Pressure drop test report
✓ Quality documentation
