Sample gas filters are used to filter finer dust from your gas analyzer system. Even when the contaminants have been removed at the extraction point through effective particle filtration inside the sample gas probe, there is still a risk of finer dust entering the gas measuring system. For this reason effective analysis sample gas filters are required, but also for use in stationary or portable sample gas conditioners. These can be in-line filters or panel filters with housings made from various material combinations. Equipped with easy to change filter elements with various retention rates and an adequate filter size they can be used for a wide range of applications.

Heated Sample Gas Filter AHF-22
Gas analysis is a complex field. The sample gas to be analyzed must be extracted and handled under quite diverse conditions to yield representative and reliable analysis results. One disturbance variable which must also be eliminated is aerosols.
The aqueous suspended particles can easily be removed from the gas by coagulation using special filter matrices. During this process, the tiny aerosols accumulate on the fibers of the filter matrix through collision, forming drops increasing in size. Once large enough, the condensate which forms drains into the filter bowl and is then removed. Model K-AGF-PV-30-A has the PVDF and glass housing from the AGF-PV filter series, using suitable fittings to adapt it for the coagulation function. The easy installation and the Unique quick-release fastener are additional features of this model.
Specifications
- Simple, sturdy construction
- Easy to install
- Tool-less filter element change
- No disassembly required to replace filter
- Controlled or self-regulating heater
- Calibrating gas connection optional

Ad-Absorption Sample Gas Filter BF2-S
Using so-called “self-cleaning” gas filters is worth considering for sample gas systems where secondary contamination primarily consisting of larger particles are to be expected.
The functional principle of these filters is that of the ‘Cross Flow’ process. Here a partial stream is continuously adequate for analysis is continuously extracted from the main sample gas flow. Inside the housing, the main stream is forced along the filter element in a spiral. The dirt particles from the partial stream deposited on the surface of the element are carried along by the main stream and discharged. The continuous discharge of dirt deposit results in a very long filter element life, thus low maintenance.
The BF2-S was developed specifically for these applications.
Specifications
- For fluids and gasses
- Long filter life
- Low maintenance
- Compact installation
- Pipe fitting included
