Ductless Fume Hoods - Classic Range

The ductless filtration fume hoods in the Classic Range are ideal for eliminating contaminating gas and/or solid particles/aerosols from the work space simply and efficiently. Safe, efficient and cost-effective, these protect both the user and the environment.

This range is unassembled when delivered so that it can be easily placed in any laboratory (despite narrow corridors, cramped stairways or ones that are difficult to access, etc.), substantially reducing transportation costs.

All the models in the Classic range use the new filtration system, developed and patented by Cruma (Invention Patent), which ensures the contaminating gas, fumes and particles generated inside are retained, thus constantly renewing the air inside the laboratory.

The main advantages offered are:

Filter type	Description
Type A	For organic vapors such as ketones, ethers, alcohols, xylenes… Eventually it can be used for inorganic acids, but only if used in small quantities because this activated carbon is not impregnated and the excess of acid vapors could saturate it quickly.
Type BE	For inorganic acid vapors as H2SO4, HCl, HNO3, and volatile sulfur compounds such as H2S, SO3, … It can be used with organic vapors because the activated carbon incorporates impregnation of metal compounds and neutralizing salts. It is also suitable to filter organic and inorganic compounds when they are in similar proportions.
Type F	For formaldehyde vapors and derivatives; also good for other organic compounds. Carbon impregnated with Cu leads, so that it should never be used with inorganic acid vapors.
Type K	For NH3 vapors and amines; also good for other organic compounds. Carbon with metal salt complexes impregnation.
Type ABEK	Mixed type to be used when the ratios between organic, inorganic and NH3/amines are similar.
Type D	HEPA H-14 filter (High Efficiency Particulate Air, according to EN-1822: 1998) for filtering dust and smoke particles.
