Is it safe in a classroom with children?

Yes. The lamps are inside a closed metal chamber and no radiation escapes. The unit produces no ozone and can run through the whole lesson.

Is 14.8 dB really that quiet?

That is the value measured by the manufacturer, quieter than a whisper (~30 dB). The larger models are 27.4 dB.

Is one unit enough for a 55 m² classroom?

The manufacturer recommends it for 40 m². For a 55 m² classroom the 60 m² model or two units are a better fit. The calculator above shows the air changes.

What do 0.7 air changes per hour mean?

The unit moves 70 m³ of air per hour; in a 100 m³ room that is 70% of the room’s air. Over eight hours, the air passes through the unit several times.

How often should the lamps be replaced?

The lamp life is 18,000 h: about 7 years on school days, about 2 years running day and night. The hour counter shows the exact figure.

Can it go on a wheeled stand to move it between rooms?

Yes, a wheeled stand (1.2 m) is available as an option. You will find its price next to the technical specifications, in the “Optional accessories” section.

Is it right for my room?

The manufacturer recommends this model for rooms up to 40 m² (100 m³). Enter the floor area and ceiling height of the room. We calculate how many times per hour the air passes through the unit and how many units you need.The manufacturer recommends up to 40 m² (100 m³). Enter the floor area and ceiling height of the room.

A recirculator cleans the air continuously and complements airing the room rather than replacing it. Many people or weak ventilation may call for a more powerful unit.

How it works

Air passes through a closed aluminium chamber where two 254 nm UV-C lamps damage the DNA of microbes. The radiation stays inside the chamber. There are no filters, so the only maintenance is replacing the lamps.

No filters: the only maintenance is replacing the lamps. The unit produces no ozone.

What these numbers mean

AirflowAirflow

70 m³/h

This much air passes through the UV chamber per hour. The result for the room depends on how many times per hour the room's air passes through the unit. The figure for your room is in the calculator above.This much air passes through the UV chamber per hour. In a room of 40 m² that is 0.7 times per hour, about 5.6 times in an 8 h day.

Example: 40 m², 2.5 m ceiling → 0.7 times per hour, ≈ 5.6 times in 8 hours

Timer and hour counterTimer

included

A programmable timer switches the unit on and off at the times you set. Example: a school week, Mon–Fri 7:00–17:00.Switches the unit on and off by itself, e.g. Mon–Fri 7:00–17:00. Lamp 18,000 h: ≈ 7 years on school days.

Lamp life 18,000 h: ≈ 7 years at 10 h per working day, ≈ 2 years running day and night. The hour counter shows the exact hours used.
