We answer your questions.

The most frequent questions from engineers and customers — with specific answers.

How to select the size for a room?
Formula: per 10 m² of area — one diffuser 300×300 (flow rate ~300 m³/h). For a 20 m² office — 1 unit 400×400. For an open office of 100 m² — 4-6 units 300×300. Send the plan — we will select it for free.
Will it blow directly onto the head?
No. 4-way airflow spreads across the ceiling (Coanda effect), velocity in the occupied zone<0.25 м/с по EN 13779. Лопасти регулируются — можно изменить дальность и направление.
Can it be painted in my color?
Yes. Standard — white RAL 9010. On request — any RAL color (lead time +5 days, surcharge 10%). Minimum order for non-standard color — 50 pcs.
How to clean?
The front panel is removed without tools (latches). The filter (option) is washed in water. Recommended cleaning — once every 6 months.
