High-efficiency fans for greenhouses
The Vostermans Multifan Greenhouse HAF Q Fan is a 16" circulation fan engineered specifically as a severe-duty solution for modern greenhouses and hydroponic grows. Delivering up to 3,150 CFM, this greenhouse fan creates a tight, horizontal airflow (HAF) pattern that keeps air moving evenly across the canopy without disrupting plants. Its impact-resistant polypropylene housing and blades, powder-coated steel grille, and IP55 rating make it ideal as a greenhouse ventilation fan in humid, wet, or wash-down environments.
Durable air circulation fan for harsh, humid grow rooms
A totally enclosed aluminum TEAO motor with Class F insulation (tested up to 140°F) ensures long life, excellent heat dissipation, and dependable performance in hotter-than-normal environments. Lightweight polypropylene impellers reduce wear on motor components, extending the fan’s life cycle, while sealed ball bearings and built-in thermal protection (single-phase) add an extra layer of reliability. Designed as a compact air circulation fan, the white housing and frame minimize shadowing over crops and integrate easily into serial or parallel HAF systems.
Greenhouse fan optimized for hydroponic airflow management
With variable speed capability and a 265/460V, 1/3 HP motor, this greenhouse exhaust fan alternative can be dialed in to match your exact ventilation strategy. Easy-to-mount wire guards, stackable housings, and simple access to the motor/impeller assembly make maintenance and installation straightforward, even in packed hydroponic facilities. Whether you’re building a new HAF layout or upgrading existing greenhouse ventilation fan systems, this circulation fan offers the energy efficiency, durability, and airflow performance serious growers demand.
Key benefits:
-
Designed for harsh, humid grow environments – IP55 rating, TEAO motor, and sealed ball bearings handle moisture, nutrient mist, and frequent wash-downs common in hydroponic greenhouses.
-
Optimized HAF airflow for even canopy conditions – Tight horizontal airflow pattern reduces hot/cold spots, improves CO₂ distribution, and supports more uniform growth across the entire grow area.
-
Energy-efficient performance – Improved efficiency over previous versions and compliance with upcoming ErP energy regulations help lower operating costs in 24/7 hydroponic operations.
-
Compact, low-shadow design – White housing, compact frame, and stackable venturi reduce shading over plants and make it easier to position multiple fans in dense grow setups.
-
Durable, long-life construction – Lightweight polypropylene impeller, Class F insulation, corrosion-resistant hardware, and permanently lubricated motor extend service life and reduce downtime.
-
Easy to install, maintain, and integrate – Simple mounting options (profiles or chains), removable wire guards, variable speed capability, and optional accessories make it easy to fit into existing HAF or greenhouse ventilation systems.
