RS Components is the first distributor to stock a new ground-breaking series of filter fans from STEGO with a new air flap outlet technology that prevents localised hot pockets forming in installations, protecting electronic components from overheating.
 The Filter Fan Plus FPI/FPO series is designed to provide cooling by efficient forced air circulation in enclosures and cabinets containing electrical, electronic and other components. Ideal for engineers that need to design or maintain systems and enclosures containing sensitive components that need to work reliably at all times, whatever the climatic conditions.
Featuring two optional systems – the FPI (in) or the FPO (out) system –enabling engineers to select the correct fan depending on requirements. The FPI system with airflow direction ‘in’, consists of a filter fan and exhaust filter where the filter fan located in the lower part of the enclosure and draws cleaner, cooler air into the enclosure. The FPO system with airflow direction ‘out’, consists of an intake filter and exhaust filter fan where the filter fan is located in the upper area of the enclosure to draw warmer air out of the enclosure.
The Filter Fan Plus series uses a new air-flap technology on the air-outlet side, which allows the fan to provide a high degree of airflow. The air-flap technology allows significantly more air to exit, so a smaller filter fan can achieve the same volume of airflow output as a much bigger device, saving time and installation space. When the fan is in idle mode, the recessed flaps remain closed keeping dirt out and protecting the operating lifetime of the fan.
The range also contains a unique ratchet-mounting mechanism that can be inserted and mounted tool free into the cutout of the enclosure, enabling easy installation and safe and secure mounting, while also guaranteeing a tight seal. The fan can be opened using only a screwdriver, which provides improved access protection and better safety.
 The full range of units in the series are available including five enclosure cut-out sizes from 92 x 92mm to 291 x 291mm, and featuring varying air volume capacities, which covers all relevant applications and customer requirements.
