Ametek DFS Nautilair brushless DC variable speed blowers have been engineered to provide practical, compact, and efficient combustion solutions, and their performance levels have tested higher than many competitor blowers of the same size. Nautilair blowers are designed to deliver a precise, measured level of air and fuel mixtures in gas-fired burner systems and come in three size options: (a) 7.6” / 193 mm; (b) 8.9” / 226 mm; and (c) 12.3” / 312 mm. All Nautilair blowers are programmable for various speed control profiles and allow for three primary speed signals: 0-10VDC electrical analog; pulse width modulation (PWM); and mechanical potentiometer (directly on the blower unit). The Ametek Nautilair brushless DC combustion blower motors are used in a variety of applications, including residential and commercial heaters and boilers, food service equipment such as ovens, and even fuel cells, among many others.

The Ametek Nautilair 7.6” brushless blower model / part number 150143-00 is RoHS and REACH Compliant.
