Formed on the basis of a combination with industrially produced electrostatic filters designed to remove dust and aerosols from the air being purified.

Photocatalytic blocks with a capacity of up to 500 m3 / h each, allow to form a channel system of the required performance and efficiency by their parallel or serial connection.

The main drawback of electrostatic filters is the ozone emission during operation - completely eliminated by photocatalysis.
Channel systems "Tivale" do not have replaceable filters. It is required only their periodic maintenance (about once a year when working as a supply ventilation).
