Enermax is pleased to announce, for the first time at the 2016 CES, that ENERMAX is making a giant leap forward for the future fan product specification, the patented DFR (Dust Free Rotation) design. The concept of DFR design is to greatly reduce the dust of the internal PC system or the fan blade. The revolutionary DFR function allows the fan to spin in reverse action at the highest RPM set by the user for 10 seconds upon startup before it resume to the normal operation. In conjunction with ENERMAX's patented DFR and Twister Bearing Technology for easy blade removal, the new D.F. Fan series offers a total solution for self-cleaning: prolong the product lifetime and extend the intervals for fan and system cleaning maintenance.

Based on our successful TwisterPressure series with incredible static pressure of 3.845mm-H2O; the new DFR embedded D.F.PRESSSURE not maintain this industry-leading performance, but with brand new APS (Adjustable Peak Speed) PWM side control configuration for maximum user safety and usability. This is truly an ultimate DIY fan choice for all types of PC chassis, CPU coolers and other indoor applications.
