Filter Media

Hydrophobic laminated glass fiber


Connect the universal oxygen filter outlet to the nebulizer inlet. Connect the nebulizer filter coupler to the filter inlet. If positioning the filter at the nebulizer inlet is not convenient, reverse the filter coupling. Then fit the filter inlet to the nebulizer filter coupler on the unit. Connect the nebulizer tube on the filter outlet.


Besides care during handling and sterilization, maintenance is limited to replacement of a filter when it becomes so loaded with particles that it offers too great a resistance to gas flow. Since relatively high pressures are used to power a nebulizer, build up of particles in the filter becomes important only when the desired fog cannot be obtained from a nebulizer. If the output of a nebulizer is deficient, check its output with the filter removed. If this removal corrects the output, the filter should be replaced.
