Vane-type (blade) mist eliminators
Curved channels: inertial deposition of droplets on the walls, gravity flow to the drain.
Open the family →Engineering atlas of mist eliminators
Separate drops from the stream — before they escape into the system
Constructive families, applicability conditions, preliminary calculations and a datasheet questionnaire for the manufacturer. No datasheet promises — only verifiable engineering logic.
- 01Check the air velocity in the section — in 30 seconds
- 02Compare 4 constructive families by conditions, not by advertising
- 03Assemble the questionnaire and pass it to your supplier

Airflow velocity in the section
Decimal separator — dot or comma. Values are positive.
—m/s
A_face = — м²formulayour input
with k_open:— м/с · A_free = — м²
The result appears after a correct input. Worked example: Q=7200, W=1000, H=500 → 4 m/s; with k=0.8 → v_free = 5 m/s.
Constructive catalog
Four constructive families
Each row is a class of construction: the separation principle, where it applies, and what to verify before choosing. Datasheet figures are never replaced by typical numbers.
Mesh mist eliminators
Mesh layers: droplets collide, merge and drain. Requires washing when fouled.
Open the family →Coalescent (fiber bed) mist eliminators
A fibrous layer grows fine droplets into visible ones; then gravity or a second stage takes over.
Open the family →Hybrid mist eliminators
Stages of different principles in series (e.g. coalescing + vanes). Verify each stage.

Installation points for mist eliminators
The place in the system defines the duty: after a cooling coil, a humidifier, a spray chamber, at the air intake, or in wet gas scrubbing.
Mist eliminator after a cooling coil
Condensate on the cooling coil fins is carried away by the stream: the place of the mist eliminator, selection inputs and a velocity check before contacting a manufacturer.
Mist eliminator after a humidifier
A humidifier releases aerosol drops; steam is not drops. Separating the tasks, the inputs and design options with verification against the data sheet.
Mist eliminator in a spray chamber
At the spray chamber outlet there is a dense curtain of drops from the nozzles: the role of the separator, the inputs and a check before ordering.
Mist eliminator in wet gas scrubbing
After the scrubber the stream carries drops of the scrubbing liquid: an aggressive medium, materials and fractions with caveats; inputs for a request to the manufacturer.
Calculators
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 |

Handbook
Short answers to common questions
How a mist eliminator works: three mechanisms without magic
Inertia, interception (capturing), coalescence — how the physics of drops separates liquid from the stream and why the design determines applicability.
How to select a mist eliminator: five steps
Five verifiable steps of mist eliminator selection: the point, the duty, the family, the calculations, the data sheet and the questionnaire.
Flow velocity: face, free and vane channels
Three velocities found in mist eliminator documentation: face, free area and local in the channels; when to use each.
Pressure drop ΔP: how to read it and where the coefficient comes from
How to read the ΔP of a mist eliminator: ζ from the data sheet of the specific model, the section reference, typical mistakes when transferring coefficients.
The site is not a shop and not a product data sheet: it is an engineering atlas. It helps you follow the route “problem → mist separation principle → design type → calculation → constraint check → questionnaire” and prepare a correct request to a manufacturer. All calculations run locally in your browser; numerical characteristics of specific models are deliberately not published — their place is the manufacturer documentation.
