AC External Rotor Axial Fan Drum Type
FZY series are widely used in industrial and mining enterprises, civil construction wall exhaust, post air,ventilation pipe.
Introduction
AC External Rotor Axial Fan Drum Type is widely used in ventilation and air conditioning systems in the chemical industry, light industry, medicine, metallurgy, power plants, transportation, and storage workplaces. It can meet the needs of industries that require a lot of ventilation, heat dissipation, and cooling, and can also be used for ventilation, exhaust, and air purification in buildings and workshops. The product consists of a rotor single-phase capacitor-run asynchronous motor or a three-phase asynchronous motor, a double-flange cylindrical housing, a grille, and fan blades. The scientific structure and high-quality components make it have excellent performances such as large air volume, small vibration, low noise, and reliable operation.
Features
AC External Rotor Axial Fan Drum Type uses a pure copper motor, so it runs very efficiently and stably and has good moisture resistance.
The carbon steel housing is painted for strength and good wear and corrosion resistance.
The outer protective cover is designed not only to avoid external damage but also to protect the safety of those around it.
The product has a wide application range and can be used in an environment of -40°C~+64°C.
Product Specification:
Hongke FZY series external rotor axial flow fan
Three types of installation methods are available to meet different usage scenarios

Use environment:
Ambient temperature: -40℃~+64℃
Altitude: 55Kpa (2500m)
Relative humidity: 90%~95%
High-power pure copper motor
The movement adopts 100% high-quality copper wire, which has the advantages of fast speed, strong moisture resistance, large air volume, low vibration, low noise, etc.

Laser cut carbon steel housing
Thickened painted carbon steel shell, advanced laser cutting machine precisely cuts the shape, and the cutting surface is smooth and flat. The surface is treated with high temperature spray painting, which has the characteristics of wear resistance, corrosion resistance, light weight, high hardness, impact resistance, and drop resistance.

Metal protective net cover
The protective metal spray paint dense net prevents damage to the fan caused by sucking in the debris pile when the fan is running, and at the same time protects the safety of personnel.
