Product Description

Intelligent Technology Ductless Filtered Balance Weighing Hood

XC- D series ductless filtered balance weighing hood is compliance with NFX15 211:2009(ANSI Z 9.5-201), ASHRAE 110:1995 standard and China national standard JG/T385:2012, certificated by ISO9001.

Specially designed for safe weighing of toxic chemical powders and reagents.It adopts negative pressure airflow to ensure good control of concentration, filtration effect, and accurate weighing and balance stability, can meet the weighing precision of one in 100,000, to ensure the safety of laboratory operators.

The balance weighing hood has the same configuration with the fume hood, without the countertop and cart, which needs to be equipped with a dedicated balance table (specifically for weighing), shock absorption.

Working Principles

1. Air inlet

Air can be pumped directly from the laboratory into the fume hood, creating negative pressure, and the steady face velocity forms a natural barrier to isolate users and the chemicals they operate with.

2. Comprehensive filtration system

The fan system will suck the toxic and harmful gases upwards, and return clean air to the room after filtration. The excellent control concentration of the cabinet can ensure that the chemical gas in the cabinet will not return to the room and cause pollution.

3. Purify the laboratory air

Different filters are configured according to different operations to effectively filter toxic and harmful gases, purify the laboratory air, remove chemical residue odor, and  the level of laboratory cleanliness.

4. Purify the surrounding air

The continuous filtration efficiency of the fume hood can help to purify the indoor air.



 no need to install pipeline engineering, convenient installation, no exhaust gas, new environmental protection.


DCBL fan, super quiet, no spark static, stable performance, long service life.
