Fume Hoods from Cruma



  • Designed to handle low toxic products are made of steel plate with antiacid polymerized epoxy coating and methylpropile no of high resistance.
  • The toxic chemical products are not released outside but retained within the filter.
  • No building work is needed to install ducts to channel the gas outside.
  • It can be used in areas where it is difficult to remove/extract contaminated air, such as from the lower levels in buildings that have a number of floors.
  • The air that is sucked in is not expelled but recirculated back into the lab after the contaminating substances have been removed. This means that it is not necessary to increase the use of the air-conditioning or heating systems to compensate for the air removed.
