Ductless Fume Hoods

Ductless fume hoods by Air Science® protect your personnel and the environment from toxic or volatile chemicals so that you can concentrate on what matters most: your work. Continuous airflow across the work surface draws contamination away from the user, recycling clean air back into your laboratory. Our ductless fume hoods provide energy savings, safety and convenience and are available in a variety of configurations, including mobile fume hoods and polypropylene fume hoods.
