Laboratory ductless Fume Hood ASHRAE 110 standard exhaust chemical fumes clean room hood


Product introduction:

Laboratory fume hoods are a type of ventilation system with the primary function to exhaust chemical fumes, vapors, gasses, dust, mist

and erosol. Fume hoods also serve as physical barriers between reactions and the laboratory, offering a measure of protection against inhalation exposure, chemical spills, run-away reactions and fires.

A typical fume hood has a box like structure with a moveable sash window. Experimental procedures are performed within the hood

which is consistently and safely ventilated, usually by means of an extract blower and ductwork. Chemical fumes are exhausted and diluted many times over in the atmosphere and have a negligible effect on human health. When environment concerns are of importance, an extract treatment system, often referred to as a scrubber is installed to remove most of the vapors from the exhaust air stream.

Laboratory fume hoods only protect users when they are used properly and are working correctly. A fume hood is designed to protect the user and room occupants from exposure to vapors, aerosols, toxic materials, odorous, and other harmful substances. A secondary purpose is to serve as a protective shield when working with potentially explosive or highly reactive materials. This is accomplished by lowering the hood sash.

Product feature:

1. The fireproof high-density board material is frame, and the experimental area is made of stainless steel (PP) veneer. It has good sealing, beautiful appearance and strong durability.

2.Negative pressure form effectively discharges experimental gas from the working area.

3.Digital display LCD control panel, fast, medium, slow, three-speed speed control.

4.Working area is 304 brushed stainless steel, easy to clean, anti-corrosion.
