Reliable Performance Rectangular inline Duct Fan

Long Life Rectangular Duct Fan (in-line)
Material:galvanized sheet steel
Feature:small volume,reliable performance,long life

Specification
Performance Specifications
Air performance parameters using ISO 5801 standard test; test air density is 1.2kg / m ; dynamic pressure and the
wind speed calculated by the outlet area.
motor
External Rotor Motor protection grade IP44 F insulation and sealed bearings suit for continuous operation. Thermal
overload protection power supply: single phase / 220 ~ 240V/50Hz.There is external junction box to the power
connector and adjustable speed.
Operating Conditions
For general indoor use, high-speed fan for temperature -20 C ~ 50 C. Low-speed fan for temperature -20 C ~ 40
C. The temperature range for the general value, the maximum operating temperature depends on the actual operational
environment and working conditions.
Fan structure
Antiseptic spray treatment by the fan casing
Antiseptic spray treatment by the fan casing
After debugging use impeller balancing test to ensure reliable quality electrical accessories. All motor through the CE
and 3C certification.
Feature
The unique professional design of its appearance ensures that it is not necessary to add accessories to install. It is
suitable for the size of the blast pipe saving more installation cost and time. Additional barriers to meet such as
hospital and commercial office buildings and other places where requires the use of low-noise operation. In addition,
such as warehouses, factories and other rooms or a larger air volume ventilation system, RK Series rectangular duct
fans provide better models of choice.
Application
Forward curved or backward curved centrifugal impeller adoption is up to its model. It is broadly applied in
large-scare ventilation system of laboratory and library.
