Circular diffuser

Circular Diffuser

Circular diffuser

Description

The inner layer of the blade can be adjusted up and down according to different air supply conditions in summer and winter. In summer, it is horizontally supplied with air (the blade is flush with the outer frame), and in winter, it is vertically aired (the blade is recessed into the outer frame).

There is a fabricated connection between the blades, no solder joints.

Inner blade can be easily disassembled at any time

Material：Aluminum plate (die stamping)

Surface treatment:electrostatic spray, baking or anodizing

Can be added accessories:C1 round rectifier switch, C2 round rectifier, C3 baffle rectifier, C4 round connector

Neck Size：ø150ø200ø250ø300ø350

We can offer Customized service.

Technical parameters

Note：1. H-----Horizontal blown value

V-----Vertical blown value

2. Arrival distance is the value of the wind speed at the 0.5 m/s position.

3.“-” means the noise is below 20dB
