AirBench Dust & Fume Extraction Benches: The Complete Buyer's Guide

A workshop, lab, or conservation bench that handles fine dust, solvent mist, or solder fume without local exhaust ventilation is operating on borrowed time: regulators in the UK, the EU, the US, and Singapore all now expect airborne contaminants to be captured at the point they are generated, not diluted into the room. Micrographics Data has added the AirBench dust and fume extraction range to its equipment catalogue for exactly this reason — the same single-source philosophy that already covers microfilm, COM systems, and conservation supplies now extends to the extraction equipment that keeps the workshops and studios around that equipment compliant. This guide explains how downdraught extraction benches work, how AirBench's seven filter classes map to real applications, which model fits which job, and the standards — from the UK's HSG258 and COSHH to Singapore's SS 658:2020 — that govern local exhaust ventilation wherever you operate.

What Is a Downdraught Extraction Bench?

A downdraught extraction bench is a form of local exhaust ventilation (LEV): a fan draws air downward through a perforated work surface and a replaceable filter, capturing dust, fume, or smoke at the source before it reaches an operator's breathing zone. In the UK, LEV design, testing, and maintenance is covered by HSE guidance document HSG258, Controlling airborne contaminants at work, and by the Control of Substances Hazardous to Health (COSHH) Regulations 2002. In Singapore, the equivalent reference point is SS 658:2020, the Singapore Standard code of practice for the design, operation, testing, and maintenance of local exhaust ventilation systems, which sets out both engineering requirements and competency requirements for the people who design, test, and maintain LEV equipment.

AirBench's range is built around 2mm welded steel bodies with a 3mm perforated steel work surface, powder coated, and rated from 50kg surface loading as standard up to 500kg on request — heavy enough for sustained industrial use, not just occasional bench-top jobs.

AirBench Filter Classes: Matching the Bench to What You're Extracting

The part of an AirBench that determines what it can safely extract is the filter class, not the bench body. Seven classes cover the overwhelming majority of workshop, lab, and conservation applications:

Filter Class	Rated For	Typical Applications
A – Non-sparking dusts	General atmospheric dust	Aluminium, plastics, GRP, flour-type dusts, electronics cleaning
F – Fine dusts	General-purpose fine dust	Carbon fibre finishing/sanding, softwood dusts, powder sampling
B – Very fine dusts	Sub-micron dust, including RCS-adjacent work	Fingerprinting, rapid prototyping, model making, conservation and restoration
L – HEPA filtered	Hazardous and fine dusts requiring HEPA capture	Pharmaceuticals, hardwoods/MDF, laboratory, optical, clean packing areas
C – Dust with light sparks	Abrasive work producing sparks	Fettling, sanding, deburring, dressing of welds
E – Low-volume fume	Solvent and adhesive vapours (not MEK)	Solvents, conformal coatings, adhesives, airbrushing
S – Smoke and fume	Combustion and thermal fume	Soldering, brazing, conservation work

Two of those seven classes — B and S — are rated specifically for conservation and restoration work, which is why AirBench sits naturally alongside Micrographics Data's existing museum-quality archival supplies and museum and library exhibition supplies: the same institutions digitising and preserving heritage collections often also need dust- and fume-safe workbenches for paper conservation, object cleaning, and bench repair.

Which AirBench Model Do You Need?

AirBench's bench bodies are differentiated by access, loading, and specialised duty rather than filter class alone:

Model Range	Design	Best For
FN	Front-access filters, 50kg standard loading	General workshop use where filters need regular front access
FP	Top-access filters, heavy duty	Higher surface loading and custom mounting attachments
FPK / FKS	Knee-space cut-outs	Seated, close-inspection work such as fine assembly or conservation bench work
FPW	Welding/grinding duty	Combined spark and fume capture for welding bays
DF	Downflow workstation	Lighter-duty laboratory and light industrial fume extraction
BD / BDS	Blowdown stations with integrated air gun	BD: swarf and coolant mist. BDS adds a carbon filter and ATEX fanset for solvent mist
WB	Wet-filtered (water bath primary filtration)	Titanium and reactive-metal grinding
RP	Pulse-clean self-cleaning filters	Continuous, high-volume stone or mineral dust
FX	ATEX zone 22 / zone 2 rated	Dust extraction in areas with an occasional explosive-atmosphere risk under DSEAR
FE	Exhaust-to-atmosphere, ducted	Sites where filtered exhaust can vent outdoors
DB	Drop-in unit	Retrofitting extraction into an existing workbench
VertEx VA / VAW / VS	Modular cross-draught systems	Applications too large for a bench — VAW for welding/grinding, VS in stainless steel for cleanrooms and pharmaceutical use

Compliance Anchors: COSHH, DSEAR/ATEX, HSG258, and SS 658:2020

Local exhaust ventilation isn't a nice-to-have — it's regulated wherever AirBench ships. The BDS range states explicit compliance with HSG258, the UK HSE's core LEV guidance, while the FX range is built to operate under DSEAR (the Dangerous Substances and Explosive Atmospheres Regulations 2002), with all filters and electrical components independently certified for use in zone 22 or zone 2 explosive-atmosphere areas. The COSHH Regulations 2002 underpin the general UK requirement to control exposure to hazardous substances at source, which is precisely what a correctly specified downdraught bench does.

In Singapore, the governing reference is SS 658:2020 — the Singapore Standard code of practice for the design, operation, testing, and maintenance of local exhaust ventilation systems — which sets both engineering requirements and competency requirements for LEV designers, testers, and maintainers. Facilities operating under Singapore's Workplace Safety and Health framework should treat a correctly specified and regularly tested extraction bench as part of their statutory exposure-control obligations, not an optional upgrade.

Why Workshops, Labs, and Conservation Studios Across APAC Are Adding Extraction Now

Workplace exposure enforcement has tightened across the region at the same time as fine-dust and solvent-fume processes have grown — from additive manufacturing and rapid prototyping to the expanding conservation and restoration work tied to Southeast Asia's heritage digitisation programmes. A bench specified against the wrong filter class, or with no filter class consideration at all, is one of the more common and most easily avoidable compliance gaps a regional audit turns up. Adding AirBench to Micrographics Data's catalogue means the archives, museums, and corporate clients already buying microfilm supplies, COM systems, and conservation materials from us now have a compliant extraction option from the same supplier, shipped across Singapore and the wider Asia-Pacific region.

Frequently Asked Questions

What is a downdraught extraction bench?

A downdraught extraction bench is a local exhaust ventilation (LEV) workbench that draws dust or fume downward through a perforated work surface and a filter, capturing contaminants at the point they are created. AirBench, now available through Micrographics Data, builds its range around interchangeable filter classes so one bench platform can be configured for dust, sparks, solvent fume, or smoke.

Which AirBench filter class do I need?

It depends on the contaminant: Class A suits non-sparking dusts such as aluminium or plastics, Class B suits very fine dusts including conservation and restoration work, Class L adds HEPA filtration for pharmaceuticals and hazardous dusts, Class C handles dust with light sparks from fettling or deburring, Class E captures low-volume solvent fume, and Class S is rated for smoke and fume from soldering, brazing, and conservation work.

Is AirBench ATEX rated for explosive dust atmospheres?

Yes. The AirBench FX range is ATEX rated for use in zone 22 (or zone 2) areas assessed under DSEAR as carrying an occasional risk of an explosive atmosphere, with independently certified filters and electrical components.

Does Micrographics Data ship AirBench internationally?

Yes. Micrographics Data supplies the AirBench dust and fume extraction range across Singapore and the wider Asia-Pacific region, alongside its existing global microfilm, COM, and conservation equipment lines.

What standards do AirBench extraction benches comply with?

AirBench models reference HSG258 (UK HSE local exhaust ventilation guidance) and the COSHH Regulations 2002, with the FX and BDS ranges built around DSEAR/ATEX requirements. In Singapore, LEV systems fall under Singapore Standard SS 658:2020.

Can an AirBench be used in a conservation or heritage workshop?

Yes — AirBench's Class B and Class S filter options explicitly cover conservation and restoration work, making the bench suitable for paper conservation, object cleaning, and bench-top restoration alongside its more common industrial and laboratory uses.
