Yamato LDC1 Series

Fume Hoods | Environmental Type, Multi-Stage Packed Tower Method

LDC1

Environmental fume hood with a multi-stage packing method exhaust treatment device that processes harmful gases.

Adopting a multi-stage packed tower method, it achieves higher gas-liquid contact efficiency and reduces pressure loss, improving maintainability, and effectively removes inorganic gases through chemical washing.

• By integrating the treatment device into the fume hood, it saves space and reduces overall setup costs.
• By achieving low pressure loss through proper wind tunnel design, it aims to save energy and reduce operational costs.
• The circulating water bath can be pulled out, and there is a piping inspection port on the back, making it easy to access. Additionally, a filter is installed on the pump circulation system, improving maintainability.
• Equipped with door fall brake block, exhaust delay timer, and washing tower water level abnormality sensor, it creates a safer research environment.
