These compact filters ePM1 50% are used in the HERU K energy recovery units.
The filter kit contains two filters, the same size for supply and exhaust air.
Energy efficient air filter classes according to EN ISO 16890.
- ePM1: Filtration efficiencies 50–95%. Particle size up to 1 µm.
- ePM2,5: Filtration efficiencies 50–95%. Particle size up to 2.5 µm.
- ePM10: Filtration efficiencies 50–95%. Particle size up to 10 µm.
- Coarse: Filtration efficiencies not required. Particles all sizes.
