Vane-type (blade) mist eliminators
Inertial deposition at channel bends — works only in horizontal flow
Check the velocity: Orientation and drainage are mandatory · Velocity — per the model datasheet
Open the family →Catalog of mist eliminator design families
Four design families — choose by conditions, not by advertising
Mesh mist eliminators
Droplet capture and coalescence on mesh layers — service and washing are mandatory
Check the velocity: Access for washing · Droplet load — per the datasheet
Open the family →Coalescent (fiber bed) mist eliminators
Fine aerosol grows into visible drops inside a fiber bed
Check the velocity: Chemical compatibility of the medium · Fibre release — per the datasheet
Open the family →Hybrid mist eliminators
Two stages of different principles — each verified separately
Check the velocity: Stage velocities must be matched · The unit is engineered, not a catalogue item

| Feature | Vane-type (blade) mist eliminators | Mesh mist eliminators | Coalescent (fiber bed) mist eliminators | Hybrid mist eliminators |
|---|---|---|---|---|
| Separation mechanism | Inertial deposition of drops on the channel bends | Droplet capture on the mesh wires and coalescence into larger drops | Coalescence of fine aerosol on the fibers | Sequential stages of different principles |
| Mounting orientation | Horizontal flow; the pack is installed vertically | Various orientations are possible — per the model data sheet | Per the model data sheet; often combined with a second stage | Per the assembly configuration |
| Drainage | Gravity-driven, by gravity into a drain pan with an outlet | Collected liquid runs downward; the arrangement depends on the model | Large drops are removed by gravity or by a second stage | A separate drain for each stage |
| Fouling sensitivity | Moderate; service access for washing and inspection | Elevated; washing per the service schedule | Depends on the medium; monitor fiber carryover | Determined by the stages; monitor the total ΔP |
| Typical verification limits | Orientation, drainage arrangement, velocity per the model data sheet | Droplet load, access for washing, velocity per the data sheet | Chemical compatibility of the medium, fiber carryover, ΔP per the data sheet | Velocity matching between stages, independent drains |
| Efficiency / limit velocity / ΔP | Efficiency and maximum velocity — from the model data sheet only | Efficiency and ΔP — from the model data sheet only | Fractional efficiency and ΔP — from the model data sheet only | Stage characteristics — from their data sheets; the assembly is a design decision |

Four calculations to run before writing to a supplier
Each tool is a separate page with its formula, worked example and limits. All calculations run locally in your browser.
| Tool | Input | Result | What it does not do |
|---|---|---|---|
| Airflow velocity | Q, W, H (+ k_open) | v_face, A_face; v_free with k | does not replace the model datasheet velocity |
| Required section | Q, v_target (± W or H) | A_req, H_min / W_min | never inserts a “recommended velocity” |
| Pressure drop ΔP | ζ (from source), ρ, v_ref | ΔP, Pa | no ζ — no result; invents no curves |
| Energy impact of ΔP | Q, ΔP, hours, η | power and energy/year | does not replace the electricity bill |
