Aquaculture air blower HVL series

centrifugalrotor

Overview
Kongskilde HVL aeration blowers deliver high air volumes for drying and ventilating grain and other crops. Designed for silo and on-floor ventilation, these units also suit industrial exhaust and ventilation tasks and can operate independently of integrated air distribution systems.

Models

• Available models: HVL 30, HVL 55, HVL 100, HVL 150, HVL 250, HVL 400G, HVL 500G, HVL 600G. Larger models (HVL 400G–600G) provide additional configuration options on request.

Features

• Maintains consistent airflow despite changing silo pressure or crop resistance (suitable for small-seed crops such as rapeseed, clover, mustard).
• Minimal air temperature rise to preserve crop quality during storage.
• Suitable for agricultural ventilation and industrial exhaust/ventilation installations.
• Parallel installation of smaller HVL units enables flexible layouts and lower electrical demand for partially filled systems.
• Backward-curved rotor blades for high airflow at optimal efficiency.
• Galvanized steel construction for outdoor and weather-resistant use.

Benefits

• Versatile installation: Compatible with both small and large setups and with horizontal or vertical mounting for HVL 30–250 without extra parts.
• Durable construction: Galvanized steel resists weathering for outdoor applications.
• Quiet operation: Backward-curved rotors reduce noise and vibration while improving efficiency.
• Low maintenance: Direct-driven motors reduce service time and costs.
• Optional accessories: Vibration dampers (HVL 30–250) and rain covers available for outdoor protection.

Air Outlets

• V1: Standard outlet for HVL 30, 55, 100, 150, 250.
• V1 and H1: Standard for HVL 400G, 500G, 600G.
• Additional outlets (e.g., V4, H4) available on request for larger models.

Applications
Kongskilde HVL blowers are suited to drying and ventilating grain, maize (corn), peas, grass seed, hay, beets, onions and potatoes. They support silo aeration, on-floor storage ventilation and broader industrial exhaust/ventilation uses.
