Fume Extraction System
View system integration details
This page explains how Extraction Hood/Arm is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A flexible or fixed component that captures and directs fumes, vapors, or particulates at their source within a fume extraction system.
Technical details and manufacturing context for Extraction Hood/Arm
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Airflow Capacity | 500–2000 m³/h | Select based on capture velocity and distance to source. |
| Capture Velocity | 0.5–1.5 m/s | Higher for toxic fumes; lower for dust. |
| Hood Diameter | 100–600 mm | Larger diameter increases capture area. |
| Arm Length | 1–3 m | Longer arms provide greater reach but may require support. |
| Operating Temperature | -20–120 °C | Above 120°C may require heat-resistant materials. |
| Pressure Rating | 0.1–0.5 MPa | Typical for fume extraction systems. |
| Material | PP, PVC, 304 SS | PP for corrosive fumes; SS for high temp. |
| Weight | 5–30 kg | Affects mounting and support requirements. |
| Joint Rotation Angle | 0–360 ° | Full rotation allows flexible positioning. |
| Noise Level | ≤70 dB(A) | Lower noise for operator comfort. |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The airflow capacity typically ranges from 500 to 2000 m³/h, but the required value depends on the capture velocity needed and the distance to the source. Always verify with the manufacturer for your specific application.
Common materials include galvanized steel, stainless steel, aluminum, and flexible PVC for ducting. For corrosive fumes, polypropylene (PP) or PVC may be used, while stainless steel (304 SS) is suitable for high-temperature applications. Confirm material suitability with the supplier.
The standard operating temperature range is -20 to 120°C. If temperatures exceed 120°C, heat-resistant materials may be required. Always check the manufacturer's specifications for your specific model.
The joint rotation angle can be up to 360 degrees, allowing flexible positioning of the hood near the emission source. This helps achieve optimal capture efficiency. Verify the rotation capability with the manufacturer.
