Conical Pre-Filter for Anemostats

The G2 class conical filter serves as the primary line of defense for your ventilation system. Installed directly into the ceiling diffuser (anemostat), it intercepts coarse debris, dust, insects, and kitchen grease before they can enter the ductwork and the central heat recovery unit.

The specialized conical shape provides a significantly larger filtration surface area compared to flat alternatives. This allows air to circulate freely without a severe pressure drop, even when the material is partially loaded with dust. The filter is easily installed and replaced without the need for tools, making routine system maintenance quick and clean.

Key Features and Benefits

• Interior finish protection. The filter prevents the formation of unsightly dark dust rings on the ceiling around ventilation grilles, preserving the aesthetic appeal of your rooms.
• Extended lifespan of the heat recovery unit. By capturing the bulk of large particles (lint, pet hair, dust), this component significantly extends the service life of the more expensive fine filters located inside the central unit.
• Clean concealed ductwork. When used in kitchen and bathroom exhaust vents, the filter stops sticky grease and damp lint from settling on the inner walls of the pipes, preventing a decrease in aerodynamic efficiency over time.
• Crucial protection during renovation. Utilizing this filter is highly recommended during construction and finishing work. It reliably protects the sensitive motors of the heat recovery unit from the damaging effects of fine construction dust.
