PreFilter - Model VE 112 - All Heated Sample Filter & Interface Analyzer
From Heated FID Analyzers - Sampling Accessories
The VE 112 is an efficient, all heated, low pressure drop sample filter and interface for removing solids from a gaseous sample and supplying sample to up to 5 gas analyzers. It utilizes a permanent all stainless steel 2 micron mesh filter and all stainless steel valve in a thermostatically controlled oven to prevent the loss of high molecular weight hydrocarbons or condensation of water. The sample filter is to be cleaned by high pressure pack purge with compressed air or nitrogen.
Product Details
The Model VE 112 can be installed in the instrument rack as a complete sample interface for all relevant gas analyzers. With its filter back purge system it offers up times at comparatively low maintenance time and cost. The sample probe and sample line are both automatically cleaned from dust and condensed hydrocarbons which every filter back purge cycle. In most cases, a stack probe filter is no longer needed.
A calibration gas inlet offers the capability to test and calibrate the complete sample train and analyzer circuit. Our proprietary rear panel adapter plate system allows cold-spot free coupling of a heated sample line inside the heated oven without the need of special tools.

Major Applications
- Complete sample and interface solution for continuous stack gas emissions monitoring systems for one heated THC monitor, sample conditioner and all needed gas analyzers and monitors or sensors
- Stationary or transportable CEMs for stack analysis
- Diesel or Gasoline raw exhaust analysis and Stationary diesel engines exhaust analysis
- Removing particles from a gaseous sample where condensation of heavy hydrocarbons is not desirable
Product Overview
Gas analyzers for emissions measurement are typically exposed to heavy soot dust and condensed hydrocarbon contamination. Therefore it is necessary to filter the sample gas stream.
The J.U.M. Engineering PreFilter is an efficient, all heated and low pressure drop filter for removing solids from a gaseous sample. The Model VE 112 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 or condensation of water.
The Model VE 112 can be installed as a complete sample interface directly in the analyzer rack. With its backpurge system for the permanent installed sample filter the VE 112 offers extended up times at comparatively low maintenance cost. The sample probe and sample line is automatically cleaned from dust and condensed hydrocarbons which every filter backpurge cycle. In most cases, a stack probe filter is no longer needed.
A calibration gas inlet offers the capability to test and calibrate the complete analyzer circuit.
Our proprietary rear panel adapter plate system allows cold-spot free coupling of a heated sample line inside the heated oven without the need of special tools.
The Model VE 112 is also available as a wall or panel mount instrument for easier installation in an outdoor cabinet, or in a purged cabinet for zoned areas.
