Discover our range of centrifugal roof-mounted fans designed for optimal performance with a sleek vertical discharge format. These fans feature a very low profile design for discreet installation and are constructed with a galvanised sheet steel base for durability.
Experience high efficiency with our centrifugal backward curved impeller, available in high-strength black injection moulded plastic for models 225 and 250, or aluminium sheet for sizes 280 to 355. Each unit is equipped with an external rotor motor for enhanced performance.
The spun aluminium cowl ensures robust protection, while the On-Off isolator switch offers convenient control. Choose from models with 2, 4, or 6 poles to suit your needs.
Our motors are designed for reliability: Single-phase external rotor motors (230V-50/60Hz) are IP54 rated with class F thermal overload protection, while three-phase motors (230/400V-50/60Hz) offer speed control through frequency inverters and voltage adjustments.
