J.U.M. - Model PreFilter VE 112 - All Heated Sample Filter & Interface Analyzer - Brochure

Gas analyzers for emissions measurement are typically exposed to heavy soot dust and condensed hydrocarbon contamination. Therefore it is absolutely necessary to fine filter the sample gas stream and prevent HC memory effects in the entire sample train. The J.U.M. Engineering PreFilter® 112 is an efficient, all heated and low pressure drop interface and sample filter for removing solids from a gaseous sample. It utilizes an all stainless steel 2μm mesh filter and an all stainless steel valve in a thermostatically controlled oven to prevent the loss of high molecular weight hydrocarbons and condensation of water. The VE 112 is probably the smartest and lowest cost solution to design a complete multi component CEM.
