Ducted Chemical Fume Hood

Cruma H+

Cruma-Cabina-conducto-de-extraccion-gases-H
The new Cruma H+ ducted extraction fume hood, manufactured according to the UNE EN ISO 14175 standard, is specially conceived and designed to work with acids. The cabinet is connected to the laboratory extraction system, generating a depressurized work environment that protects the operator from all types of contaminants handled inside. There is also the option of acquiring an extractor fan made of polypropylene.

The cabinet is made entirely of polypropylene (metal free), a material with excellent chemical resistance to strong acids. Both the sides and the guillotine door are made of transparent polycarbonate with a protective sheet against acid splashes. The air flow is manually adjustable by means of a valve, thus adapting the air fl ow to the different extraction systems that the laboratory has.

Advantages

 

Manufacture: the entire cabinet is made of polypropylene and laminated polycarbonate to protect from splashes.

Work surface: there are 3 options, without work surface (you would work on top of the laboratory table, wich usually has a phenolic surface) polypropylene surface and tempered glass surface.

Side walls in polypropylene and transparent polycarbonate for greater illumination.

Extractor pipe diameter 200 mm ready to connect to extraction system.

Air diffuser: located in the upper part of the interior of the cabinet for correct suction of air and contaminants.

Guillotine-type front door: anti-splash laminated polycarbonate door adjustable to any height by means of counterweights. The cabinet has a limiter marking an optimum working opening of 395
mm. The limiter can be removed and the sash can be opened up to 680 mm.

Lighting: fluorescent lamps positioned in the central parts and fitted with a prismatic diffuser screen for a better distribution of light on the working plane.
