The McAlpine MACFILTER is a two-way active carbon filter designed for external installations to eliminate bad odors produced by the drainage system. The filter is installed on the vent pipe of the drainage system and works by absorbing and neutralizing the odors that are emitted from the pipes. The filter uses activated carbon, which has a large surface area and a high adsorption capacity, to effectively trap and remove the odorous compounds that are present in the air. The two-way design of the filter allows it to work in both directions, ensuring that all the odors are captured and neutralized. The McAlpine MACFILTER is designed for use in external installations, such as on the roof of a building or in a ventilation shaft. It is made from high-quality materials that are resistant to weathering and UV radiation, ensuring that the filter will last for many years in even the harshest env-ironments. Installation of the McAlpine MACFILTER is straightforward and can be done by a qualified plumber. The filter is compatible with a range of vent pipe sizes and can be easily adapted to fit different systems. Overall, the McAlpine MACFILTER is an effective solution for eliminating bad odors produced by the drainage system in external installations. It is a reliable and durable product that can help to improve the air quality around the building and create a more pleasant env-ironment for occupants and passersby.
