If the exhaust air smells, a filter on the vent pipe often helps. For example, the new coalsi Polylok, which Fritzmeier Umwelttechnik is now offering as an ultra-compact retrofit solution.
In manufacturing or processing industries, the odour filter is intended to protect people and the environment from unpleasant odors and is suitable for a wide range of applications. Unpleasant-smelling process or waste water air is usually due to organic compounds of sulfur, nitrogen, oxygen and hydrocarbons. Inorganic substances such as ammonia (NH3) or hydrogen sulphide (H2S) can be noticed intensively.
The passive filter is placed directly on the ventilation pipes of hall roofs, separators, small sewage treatment plants, etc., and is pressurized solely by gas pressure. The assembly can be done by yourself. There is a filling of activated carbon inside, which lasts about a year (depending on the application). The filter is available in two versions.
The smaller model measures 100 mm in diameter and is 194 mm high (the larger approximately double). Adapters ensure individual adjustment to the exhaust pipe. The activated carbon filling is available directly from the manufacturer as a pack or bag. With its brand coalsi, Fritzmeier is one of the leading suppliers.
