The Secoh JDK series is a new generation of membrane blowers. The JDK series is the result of the long-standing commitment of Secoh Sangyo Co. Ltd (Japan). This series offers even greater reliability, durability, actual performance and cost-effectiveness. The blowers are fitted with protections against overheating, rupture of membranes and displacement of magnets due to incorrect installation or use. For higher performance (from model JDK-150 onwards), the blowers in this series are equipped with a pressure relief valve to protect the blowers against overpressure. The JDK series is a partial replacement for the previous Secoh SLL and EL-S series. The Secoh JDK series is now available to customers with a free air flow rate of up to 700 l/min. At the same time, the Secoh JDK series is characterised by its cost-effectiveness (energy consumption is reduced by up to 30% depending on the model) and compactness (dimensions are also reduced by up to 30% compared to the previous counterparts), as well as its lightness.
