What to check before ordering
- Confirm the airflow class against your work: Type A2 recirculates about 70% of the air, Type B2 exhausts 100% outdoors.
- Measure the doorway, lift and bench run – a 6 ft cabinet needs clear access and a reinforced surface.
- Confirm the electrical supply and whether a stabilised or dedicated circuit is available.
- Decide who performs annual certification and how quickly HEPA filters can be replaced locally.
