Caluma’s Boxfan is a 30 cm, 40 W circulation fan designed for grow tents and small rooms. Its compact, flat housing features two mounting holes in the base for flexible placement on the floor or suspended overhead inside a tent. A three‑speed mechanical selector allows airflow to be set from a gentle breeze to stronger circulation, and a built‑in 60‑minute timer supports timed operation. The unit runs on 220–240 V at 50 Hz and is intended for indoor use. A stable stand and louvered front grille help distribute air across the canopy.
