Vosterman 18" HAF Multifan

Vostermans 18 in HAF Multifan circulation fan The Vostermans 18 in fan moves 3,860 CFM of horizontal airflow to build a uniform climate. It runs efficiently at up to 23.1 CFM per watt and stays quiet near 48 dB(A). A class F motor with thermal protection and an IP55 rating handle wet, dusty rooms. It connects easily to 20.5 in poly air tubes. Even horizontal airflow for greenhouses and grow rooms Steady HAF mixing clears hot and cold spots and the humidity pockets that lead to mildew. Growers rely on it to hold temperature and humidity even across a dense canopy. Low power draw keeps electricity costs down in a 24/7 hydroponic room. Quiet operation makes it easy to work nearby all day. The rugged build holds up near reservoirs, nutrient lines, and misting systems. A 3-year motor guarantee backs round-the-clock use. Connect it to poly air tubes to steer airflow above the canopy. Fewer hot spots mean steadier growth from row to row.
