Polypropylene Hybrid Laminar Airflow

TopAir’s Laminar Airflow Ductless Fume Hoods
combine the functionality of ductless fume hoods and
laminar clean benches.
The product is equipped with dual filtration system:
1. Supply system with a pre-filter, HEPA filter and a
fan that creates laminar down-flow towards the
working area.
2. Exhaust system with carbon filter and fan that
collects the down-flow and creates protective
inflow on the front sash opening. Both inflow and
down flow pass through the carbon filter before
the air is exhausted back into the lab.

• 8 mm welded polypropylene with high chemical
resistance
• Double back wall with baffle

steel worktop
