RVK Circular Duct Fans | Professional Centrifugal Inline Ventilation

RVK Circular Duct Fans represent the industry benchmark for commercial, domestic, and indoor cultivation climate control. Engineered by ventilation experts Systemair, these German-built centrifugal inline extraction fans are designed for permanent, 24/7 continuous operation. They provide maximum airflow efficiency with low vibration and minimal power consumption.

• Flexible Installation: Engineered to perform efficiently as a supply or extract fan, the compact housing can be mounted safely in any horizontal or vertical position.
• Hard-wearing and Casing Leakage Resistant: The lightweight, fiberglass-reinforced casing (PA6 or PP depending on the model size) protects internal components from mechanical damage and high humidity.
• Optimised Performance: Dynamically balanced, backward-curved radial impellers reduce aerodynamic noise and eliminate mechanical losses associated with forward-curved designs.
• Speed Controllable: Fully compatible with external speed regulators. Use a stepless thyristor or a 5-step transformer to adjust seasonal airflow without introducing a motor hum.
• Airtight & Wet-Room Ready: Features an IP44 or IP55 rated external terminal box and tight seals, making it perfectly suited for high-moisture ducted extractions.
• Vibration Isolation: The universal mounting bracket is included. Pair with an optional FK mounting clamp to prevent vibration transfers across your rigid or flexible ducting runs.
• Integrated Motor Protection: Built-in thermal contacts protect the external rotor AC motor from overheating. Smaller models have an automatic reset function, while larger Sileo variants use a manual electrical reset.
