The Systemair MUB Insulated Box Fan is a versatile and efficient solution designed for both supply and exhaust ventilation systems. Engineered with a robust frame and double-skin ZM310 panels, these units offer superior C5-rated corrosion resistance, making them ideal for both indoor and outdoor environments. The inclusion of 30mm acoustic and thermal rockwool insulation ensures whisper-quiet operation and high thermal performance, while the modular design allows for significant flexibility, including on-site reconfiguration for 90-degree air discharge. Available with advanced AC or EC external rotor motors, the MUB series is built to maximize efficiency and minimize power consumption. These units feature radial impellers with backward-curved blades that are dynamically balanced for smooth, reliable performance. Installation is highly adaptable, allowing for mounting in any position, or floor placement when paired with an optional base frame. With a wide range of compatible accessories—such as heaters, coolers, silencers, and filters—the MUB fan can easily be scaled into a comprehensive air handling unit tailored to specific project requirements.
