The right fume hood accessories improve safety, extend hood life, and customize your hood for specific applications. From airflow monitoring to specialty liners, these components turn a standard fume hood into a purpose-built workstation for your lab’s exact needs.

Airflow Monitors

Continuous face velocity monitoring with visual and audible alarms when airflow drops below safe levels. Digital displays show real-time FPM. Required in many jurisdictions and recommended in all labs handling hazardous chemicals. Retrofit kits available for existing hoods.

Common models include the AFA-500 and AFA-1000 series digital face velocity monitors, which mount on the hood superstructure and sound an alarm below the set fpm threshold. Before ordering a monitor/alarm for an existing hood, confirm the hood already has (or can accept) a junction box for the alarm’s low-voltage wiring, a nearby power connection, and a clear cable run from the monitor to the blower or damper it references. Labs USA can supply install instructions and photos for the specific monitor model with your quote.

Base Cabinets & Stands

Support cabinets beneath bench-mounted hoods for chemical storage, solvent waste, and general storage. Options include acid/corrosive cabinets (with integral spill containment), flammable storage cabinets (FM/UL approved), combination cabinets, and open base stands for equipment.

Interior Liners

  • Fiberglass (FRP) — General chemistry; good chemical resistance, cost-effective
  • Polypropylene — Acid digestion, HF use; excellent acid resistance
  • PVC — Acid and corrosion resistance at moderate cost
  • Stainless Steel — High-temperature work, perchloric acid, and cleanroom applications
  • Epoxy-coated Steel — Budget-friendly option for light-duty chemistry

Service Fixtures

Gas turrets, air valves, vacuum outlets, water faucets, and electrical receptacles mounted inside or on fume hood side posts. Remote-operated fixtures keep hands outside the hood during adjustment. DI water, nitrogen, and specialty gas connections available.

Additional Accessories

  • Sash stops & sash restrictors — Limit maximum sash opening for energy savings and safety
  • Work surface inserts — Drop-in cup sinks, trough liners, and hot plate recesses
  • Explosion-proof lighting — Required when handling flammable solvents
  • Exhaust blowers — Centrifugal or axial fans, fiberglass or PVC construction for corrosive exhaust
  • Ductwork transitions — Round-to-rectangular adapters, flexible connectors, and dampers
  • Shelves & storage — Interior shelves for reagent bottles and apparatus

Fume Hood Services and Utilities: What to Decide Before You Order

Service fixtures are the valves and outlets on the hood. They are easiest to get right before the hood is built, because the fixture holes, internal plumbing and the base cabinet below all depend on them. These are the questions customers most often need to answer before we can finalize a fume hood quote.

Water

Cold only, or hot and cold. Hot and cold are usually separate fixtures. Choose a cup sink or a larger sink in the work surface, and note whether you need DI water.

Vacuum breakers

Some jurisdictions require them on lab faucets to stop back-siphoning into the building water supply. Ask your plumber or inspector, then tell us so we include them.

Air, gas and vacuum

List each service and how many outlets. Natural gas needs a gas-rated fixture and coordination with your plumber; specialty gases like nitrogen are also available.

Vacuum pumps and chillers

If a pump sits in the base cabinet or a chiller line runs into the hood, we plan a pass-through or an extra opening so lines do not run under the sash.

Electrical

Number of receptacles and whether GFCI protection is required. If your engineer classifies the area as hazardous, ask about explosion-proof components.

Who connects it

Labs USA supplies the fixtures with the hood. Final plumbing, gas and electrical hookups are typically made by your licensed trades, so confirm the split of work on your quote.

Not sure yet? Send us the list of chemicals and equipment you plan to use in the hood and we will recommend a services layout. You can also configure a hood with the Fume Hood Configurator or compare options on the fume hood hub. For sinks and faucets outside the hood, see Laboratory Sinks and Laboratory Fittings and Faucets.

Frequently Asked Questions

Which services come standard on a fume hood?

It depends on the hood model. Most hoods are configured à la carte, so list each service you need (water, air, gas, vacuum, electrical) and how many outlets, and we will build the quote around it.

Can hot and cold water come from one faucet inside the hood?

Hot and cold water are usually supplied as separate fixtures rather than mixed inside the hood. Tell us your preference and we will confirm what your hood model allows.

Do I need a vacuum breaker on a fume hood faucet?

Some state and local plumbing codes require vacuum breakers on laboratory faucets to prevent back-siphoning into the building water supply. Your plumber or inspector can confirm the local requirement, and we can include them.

Can I run a vacuum pump or chiller into the hood?

Yes, when it is planned up front. We can add pass-throughs or an extra opening so hoses and lines are not routed under the sash.

Can you add service fixtures to a fume hood I already have?

Often, yes. Send photos of the hood’s side posts and its model or serial plate and we will check which fixtures fit.
