DLZF cooling fanIt is specifically designed forEvaporative condenser, closed cooling tower, air cooler, transformer oil coolingdesignLow noise axial flow cooling dedicated fan, Main focusHigh air volume, low noise, high efficiency, outdoor waterproof, high temperature/anti-corrosionIt is the core supporting equipment of industrial cooling systems.

1、 Model Naming Rules (General)

• DLZFD (low noise)+L (cooling)+Z (axial flow)+F (fan)

• No.□Machine number=impeller diameter (decimeters, 10 × mm)

  例：No.7 → 700mm、14 → 1400 mm、No.22 → 2200mm

• Second digit:Speed/number of poles（4=1450r/min、6=960r/min， 主流）

• Suffix (optional):

• S: Stainless steel

• FAnti corrosion (fiberglass/stainless steel)

• B：防爆 （ExdIIBT4/DIICT4）

• DLZF-14-6S: Impeller 1400mm, 6-pole 960r/min, stainless steel material

• DLZF-18-4B: Impeller 1800mm, 4-pole 1450r/min, explosion-proof type

Structure and Characteristics (Core Advantages)

1. impeller

• Wing shaped aluminum alloy/stainless steel molded/die cast, high strength, low wind resistance, and high efficiency

• 4-6 blades, high dynamic balance accuracy, low vibration, long service life

2. motor

• Outdoor fully enclosed waterproof motor, IP55, F-class insulation, high temperature resistance

• Standard SKF/NSK imported bearings, can be equipped with explosion-proof motors (ExdIIBT4/DIICT4)

3. air duct

• Streamlined hydraulic forming, smooth air inlet, reducing eddy currents and improving efficiency

• Surface spray coating/hot-dip galvanizing/stainless steel, corrosion-resistant and durable

4. Transmission method

• Direct connection (small machine number), belt drive (medium machine number), planetary gear (large machine number)

5. core strengths

• Low noise and high efficiency5~10dB (A) lower than normal axial current, efficiency increased by 10%+

• Outdoor DurableIP55 waterproof, anti-corrosion, high temperature resistant, suitable for outdoor cooling towers/condensers

• strong adaptabilitySpecially designed for cooling systems, with high matching of air volume and pressure

• Customized flexibilityCan be customized for special purposes such as stainless steel, anti-corrosion, explosion-proof, and wide voltage

Main application scenarios

• power industryTransformer oil cooling, substation cooling system

• refrigeration industryEvaporative condenser, closed/open cooling tower, air cooler

• Chemical/PharmaceuticalCorrosive environment cooling (stainless steel/anti-corrosion type)

• Metallurgy/IndustryHigh temperature equipment forced cooling and circulating water cooling system

Key selection points (quick matching)

1. machine numberSelect according to the size/air volume requirements of the cooling equipment (e.g. cooling tower diameter 1400mm → 14)

2. speedLow noise priority 6-pole (960r/min); Efficient high air volume selection with 4 poles (1450r/min)

3. materialAluminum alloy is selected for ordinary environments; Corrosion/outdoor selection of stainless steel; Explosion proof option B type

4. powerMatch according to air volume/pressure to avoid overload
