DXG-II-3.5 Rectangular Duct Fan/Industrial Commercial Wind Cabinet

The DXG-II-3.5 rectangular duct fan/industrial commercial wind cabinet adopts low-noise fan motor and centrifugal impeller direct drive, square inlet and outlet, can directly supply air, and is installed coaxially with the air duct without the need for a machine room. The structure is compact, low in height, and has the high flow rate of duct fans and the low noise of box fans. It has advantages such as low noise, low power consumption, easy installation, and stable operation.

Design selection instructions
1. The pipeline fan belongs to the forward multi wing centrifugal fan, and under the same air volume and pressure conditions, its noise is much lower than that of the axial flow fan. The parameters such as air volume, air pressure, and noise of this series of fans are proposed based on the practical needs of many projects, and are widely applicable to the air supply and exhaust systems in public places.
2. On the top surface of the fan casing, there is an arrow indicating the direction of the air outlet, which can avoid reverse installation and ensure the normal use of the air supply and exhaust system.
3. When the low-temperature air being transported may cause condensation on the outer surface of the casing and pipeline, an insulation layer should be designed.
4. The noise of a fan is the average value measured at a distance of one meter from the air inlet when the rated air volume and pressure are not connected to the air duct. If equipped with intake and exhaust ducts, the noise will be attenuated to some extent. For occasions with high noise requirements, soundproof elbows or silencers should be installed on the intake and exhaust ducts.
5. The power wiring diagram for the single-phase (220V) motor used with the fan is placed in the fan power junction box.
6. The vibration of the fan is minimal during operation, and generally no vibration reduction measures are required. If the design deems it necessary, damping rubber or damping springs can be added at the fan support.

Notes:

Understand the specifications, form, inlet and outlet positions, and corresponding installation dimensions of the fan, as well as the power requirements for the motor used

Before installation, the fan blades and casing should be carefully inspected for any damage or deformation caused by transportation, and the bolts should be checked for firmness. Otherwise, they should be repaired before installation and use

The C pipeline vent and fan should be equipped with interlocking devices, so that when any one of the pipeline vents is opened, the fan can automatically start

Before starting the D fan, the first thing to check is whether there are any objects inside the fan and pipeline that hinder rotation; Check if the electrical circuit is intact

After installation, regularly inspect all components of the fan and check if the bearing lubrication is sufficient to ensure that the fan can start and operate normally at any time

The rotation direction of the F impeller must be consistent with the arrow mark on the air duct
