The CF Master, with its heavy duty hot dip galvanized guard and C-Face motor mount, sets these fans apart from others in the market.

Guard Dimensions

• 20-1/2" diameter for 16"/18" standard propeller, various size custom propellers.
• 28" diameter for 24" standard propeller and up to 26-1/2" custom propeller.
• 30-1/4" diameter for 27" standard propeller and up to 28-1/2" custom propeller.
• High quality coating, long lasting protection against corrosion.

• 1/8, 1/6, 1/4, and 1/2 HP.
• Clean and sleek when assembled.
• Dual voltage and hertz, 1 and 3 phase, class F insulation.
• Motors meet IP54 standard, limiting the entrance of dust and water.

• Superior airfoil design.
• Wide range of sizes to achieve maximum CFM, minimum d(BA) (sound level).
• Three blade styles, all with high strength die cast aluminum hubs:
  Die cast aluminum.
  Nylon-fiberglass reinforced.
  Polypropylene-fiberglass reinforced.

CF Master Features

Propeller diameter starts at 28" with 3 to 12 blades, depending on CFM requirements and motor specifications. Motors start at 3/4 HP, dual voltage and hertz, 1 and 3 phase, totally enclosed, rigid mount, made specifically for outdoor use. Air flow volume to +17,000 CFM.
Three propeller material types available: cast aluminum, nylon reinforced with fiberglass, polypropylene. True airfoil propeller blades minimize sound levels and maximize airflow.
Fan guards with venturi for maximum efficiency are OSHA compliant. Arms for mounting fan to radiator are welded to guard supports for maximum strength and are pre-drilled. NOTE: The A, B, C, and D dimensions increase or decrease according to propeller and guard diameter. Mounting arm dimensions do not change. For base mounting, the motor mounting plate on rear of fan guard bolts to transformer fan support structure.
J-Series transformer cooling fans have unlimited flexibility in size, CFM, and motor specifications to meet airflow and sound level requirements most efficiently and economically.
