Portable Ductless Fume Extractor Hood

What is the Portable Ductless Fume Extractor Hood?

A portable ductless fume extractor hood is a small, movable unit with a capture hood and filter set for soldering, adhesives or light chemical tasks. It provides local extraction at the source rather than an enclosed workspace.

Overview

The unit consists of a flexible arm or fixed hood, a fan and a filter cartridge combining prefilter, HEPA and carbon layers. Airflow is 100–400 m3/h, with capture velocity of 0.5 m/s at the hood mouth at a distance of 100–200 mm. It weighs 10–30 kg, rides on a trolley and plugs into a standard 220 V supply. Noise is 50–60 dB(A). Extraction arms capture fumes from soldering or adhesive curing, while enclosures with a sash provide slightly more protection. Filter life is 500–2000 hours depending on contamination. The unit is not a substitute for a fume hood for hazardous chemicals, since capture is open and dependent on positioning.

How does it work?

A ductless fume hood uses a fan to pull room air through the sash opening at 0.4–0.5 m/s across the work area, then through one or more filter stages before discharge back into the room. A prefilter removes dust, and activated carbon beds adsorb organic vapours through physical adsorption. Chemically impregnated carbon or specialist media can capture acids, ammonia or formaldehyde. A HEPA stage can be added for particles. Sensors or timers indicate filter saturation, and airflow monitors ensure correct face velocity. Because filters have finite capacity, the hood is limited to known chemicals in limited quantities, and filter selection must match the vapour. The body is typically polypropylene or epoxy-coated steel, with lighting and a control panel.

What are the key features?

• Flexible arm or fixed hood with filter cartridge
• Prefilter, HEPA and carbon layers

• Mobile unit of 10–30 kg on trolley
• Runs on standard 220 V supply
• Filter life 500–2000 hours

What are the technical specifications?

A typical portable ductless fume extractor hood configuration offers airflow of 100–400 m3/h, capture velocity of ≈ 0.5 m/s at 100–200 mm, filter layers of Prefilter, HEPA, carbon, weight of 10–30 kg, noise level of 50–60 dB(A) and power supply of 220 V, 50 Hz, 100–250 W. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Portable Ductless Fume Extractor Hood is used in soldering stations, adhesive curing, electronics repair and light chemical tasks. Across the wider Ductless Fume Hoods class, laboratories also deploy it for teaching laboratories, quality control and pharmacies.

Which standards and certifications apply?

Relevant standards and methods include ASHRAE 110 (testing performance of laboratory fume hoods), AFNOR NF X 15-211 (ductless fume cupboards), ISO 14644-1, EN 14175-1 (fume cupboards, vocabulary), GB/T 34269 and IEC 61010-1. Certification candidates for this model are CE and ISO 9001 manufacturing; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Establish a chemical register before purchase and have the supplier confirm filter compatibility in writing. Change filters at the recommended interval or sooner if gas sensors or odour indicate breakthrough, because carbon saturation is sudden at the end of life. Test airflow and filter seals on installation and at least every 6–12 months, keeping records for audit. Place the hood away from doors and air currents, and with clearance to allow filter replacement. Dispose of used filters as hazardous waste. Train users to restrict quantities, keep sashes low and never use the hood for chemicals outside the compatibility list.

How do I select the right Portable Ductless Fume Extractor Hood?

Choose a portable extractor for low-hazard fumes from soldering or adhesives at a fixed workstation. It is not adequate for volatile toxic chemicals or enclosed processes. RFQ: fume type, distance to source, filter layers and mobility.

How does it compare with other Ductless Fume Hoods variants?

Select by the chemicals used. Every application needs a chemical compatibility assessment from the supplier to match filter media, and the assessment should include quantities, frequency and breakthrough behaviour. Choose an activated carbon filter for organic solvents, impregnated carbon for acids or amines, and HEPA for particulates. Consider filter monitoring, such as gas sensors that signal breakthrough, rather than timers alone. Choose width, typically 600–1500 mm, noise level, and whether a base cabinet for storage is required. Ductless hoods are not suitable for unknown, high-volume or highly toxic chemicals, or for heated perchloric acid. Confirm local regulations on recirculating air, since some jurisdictions restrict their use.
