Ductless Fume Hoods Class 1


The ductless filtration fume hoods included in the Plug&Play 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.
The range is already assembled on delivery (just unpack, install the filters and plug in) and all the models are equipped with the new filtration system, developed and patented by Cruma (Invention Patent), to retain the contaminating gas and fumes generated on the inside thus constantly renewing the air inside the laboratory. The main advantages offered are:
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.


Yes, they all fit and are standard.

No need to worry. It’s totally safe.

The fume hoods in the Plug&Play range were designed to ensure that practicaly no handling operations are necessary once these have been received: all you have to do is take them out of their fantastic packaging, place them in the desired spot, install the filters, plug them into the mains and get to work. As simple as their name suggests: plug in and play.

All of the Plug&Play fume hoods 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.

Cruma Filters

A wide range to ensure the air remains clean and health is unaffected

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.
