Vostermans Ventilation Fans for Agriculture & Greenhouses
Vostermans is a Dutch agricultural fan manufacturer producing the Multifan line of EC motor ventilation fans engineered for commercial greenhouse, poultry, livestock, and indoor growing applications. Multifan fans are designed for continuous-duty operation in high-humidity agricultural environments, with motors and housings that withstand the moisture, condensation, and corrosive conditions typical of commercial controlled environment growing. The EC (electronically commutated) motor technology delivers variable speed control with high energy efficiency -- EC fans consume significantly less power at partial speeds compared to AC induction motor fans of equivalent size.
EC Motor Technology for Commercial Growing
EC motors are brushless permanent magnet motors with integrated variable speed electronics. They operate efficiently across a wide speed range, which is important in greenhouse climate management where fan speed needs to vary with outside temperature, season, and production stage. An EC fan running at 50% speed uses approximately 12-13% of its full-speed power consumption -- compared to AC fans with traditional variable speed control that remain much less efficient at partial speeds. For commercial facilities running large ventilation arrays 24/7, EC fan technology produces measurable energy cost reductions over the operating life of the equipment.
Commercial Applications
Vostermans Multifan products are used in commercial greenhouse ventilation systems, large-scale indoor farming operations, and agricultural building climate management.

Vostermans Ventilation FAQ
What makes Vostermans fans different from standard grow room fans?
Vostermans Multifan products are built for commercial agricultural environments -- designed for continuous-duty operation in high humidity, corrosive atmospheres, and harsh conditions that standard grow room fans are not rated for. The EC motor technology delivers variable speed control with high part-load efficiency, which matters at commercial scale where fans run continuously and energy costs are significant. Multifan products are tested to agricultural industry standards for moisture resistance and longevity in field conditions that are substantially harder on equipment than a typical indoor grow room.
What is an EC motor fan and why does it matter for ventilation efficiency?
EC (electronically commutated) motors are brushless permanent magnet motors with integrated variable speed control electronics. They are significantly more efficient than AC induction motors, especially at partial speeds. An EC fan running at 50% speed uses roughly 12% of full-speed power, versus an AC fan with triac speed control that might use 60-70% of full-speed power at the same airflow reduction. In commercial growing operations where large ventilation fans run continuously, the energy savings from EC technology can be substantial over a season. EC motors also produce less heat and last longer than equivalent AC motors because there are no brushes to wear.
What size and type of Vostermans fans are available?
Vostermans Multifan fans are available in multiple diameter sizes from small circulation fans through large-diameter axial ventilation fans for greenhouse and barn ventilation. The range includes wall-mount, circulation, and cross-flow configurations for different airflow patterns and installation types.
