Ductless Fume Hood


ductless filtration fume hood created in response to a market that demands new products, but which is not willing to compromise on features, functions or quality. Our R+D+i department developed this model based on two fundamental premises: Economy and Ecology. Hence the name. A product that respects both the environment and the most demanding user. It is within this frame of action that the gas filtration fume hood ECO2 was born.
ECO2 underwent the same safety tests and controls as the rest of the ductless filtration fume hoods, responding to the stringent demands of our customers which all Cruma products offer.
Personnel Safety and Environmental Protection

Apart from completely protecting the person handling the material inside the cabinet, the chemical toxins produced are not released to the outside but remain inside the cabinet thanks to the filtration system formed by a variety of activated carbon filters.


These can be used in areas where it is difficult to extract contaminated air, such as the lower floors of buildings, and they can be placed in different locations, which it means that they can be easily relocated if needed.

Economic Savings and Easy to Set-Up

No expensive works are necessary to install conduits to extract the gas to the outside which means there are no additional costs and no need to interrupt a laboratory working at full capacity.

Energy Savings

Unlike traditional extraction hoods, our fume hoods do not use the air conditioning equipment inside the laboratory, which substantially reduces energy costs. The aspirated air is not expelled outside but recirculated back into the laboratory free from contaminating substances.

General chemistry involving small volumes of reagents or chemical compounds at ambient/moderate temperature in all types of laboratories:

  • Research laboratories
  • Quality control laboratories
  • Clinical and hospital laboratories
  • University and school laboratories

…In general, in any kind of laboratory.


Without fear. Safely.

The fume hood ECO 2 was designed so that all you have to do once it have been delivered is set it up: simply take it out of its fantastic packaging, assemble it easily in the desired spot, plug it into the mains and get to work. Ecological and Economical. Hence his name.

The ECO2 fume hood use the new filtration system, developed and patented by Cruma (Invention Patent), which protects the operator by retaining the contaminating gas, fumes and particles generated inside, constantly renewing the air inside the laboratory and avoiding leaks that may contaminate the environment.

Filter TypesDescription
Type AFor 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 BEFor 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 FFor 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 KFor NH3 vapors and amines; also good for other organic compounds. Carbon with metal salt complexes impregnation.
Type ABEKMixed type to be used when the ratios between organic, inorganic and NH3/amines are similar.
Type DHEPA H-14 filter (High Efficiency Particulate Air, according to EN-1822: 1998) for filtering dust and smoke particles.
