Jeio Tech Ductless Fume Hood (DLH-11G)

Jeio Tech's Ductless Fume Hoods provide laboratories with a safe and energy-saving mobile workspace free from toxic vapours and fumes without the need of costly ductwork.

Each ductless fume hood model comes with a high-quality polyester fibre pre-filter for trapping larger particles and increasing the life of the main HEPA filter. Their large-capacity blower maintains a sufficient intake flow rate and reduces noise (less than 50dB under normal operation).

The fume hood's internal airflow speed can also be easily monitored with their built-in anemometer.
