Fan coil filters

Fan Coil Unit Filters (G2):

Fan Coil Unit Filters (G3/G4):

These are coarse filters used as a first line of defense for air purification and the protection of internal coils.

What is the G2 classification?

Standard: Based on older European specifications (EU2) or current specifications (ISO Coarse).

Efficiency: Designed to capture large particles and coarse dust, with an efficiency of 50% to 60% for particles larger than 10 microns.

Function and Importance in Fan Coil Units (FCUs)

Coil Protection: Prevents the accumulation of dust and dirt on cooling or heating coils, thereby maintaining heat exchange efficiency.

Airflow Support: Ensures steady airflow without significant obstruction that would otherwise force the fan to increase energy consumption.

Extended Fan Lifespan: Protects internal fan components from wear or clogging.

haracteristics and Specifications of G2 Fan Coil Filters

Material:** Typically made from non-woven synthetic fibers (synthetic polyester) or washable polyurethane fibers.

Frame:** Usually features a lightweight galvanized metal frame or a wire frame for easy installation and removal.

Pressure Drop:** Characterized by low air resistance, which is essential for the fans in small fan coil units.

Thickness:** Standard thicknesses typically range from 6 to 10 mm.

Maintenance and Cleaning

Washability:** Many G2 filters used in fan coil units are washable with water and reusable after drying completely.

Cleaning Frequency:** Periodic inspection and cleaning are recommended (every 1 to 3 months, depending on the environment) to ensure air quality and maintain air conditioning efficiency.
