SWFSeries of high-efficiency and low-noise mixed flow fans

product overview

The SWF series efficient and low-noise mixed flow fan features a conical twisted blade with radial acceleration characteristics welded onto the hub, equipped with guide vanes for good airflow distribution and stable pressure. It has the advantages of high efficiency, compact structure, low noise, small size, and easy installation.

Model Description

give an example: SWF-I/II-No.5#

CLASSIFICATION

SWF-I (single speed) fans are divided into 18 types from 2.5 # to 14 # according to their machine numbers, with 4 types of speeds: 2900rpm (D), 1450rpm (F), 960rpm (S), and 720rpm (E). There are a total of 54 specifications, with air volume ranging from 490 to 102450m³/h. The full pressure range is from 50 to 1380Pa.

SWF-II (dual speed) fans are divided into 16 specifications from 6.5 # to 14 # according to their machine numbers.

SWF-III single speed high voltage type, SWF-D single speed low voltage type.

Divided by speed regulation method: SWF-I single speed, SWF-II dual speed, variable frequency (variable frequency motor+variable frequency controller, stepless speed regulation, it is recommended to lock the frequency between 25Hz~50Hz).

Fans can be customized with wind caps according to the needs of the location, and the identification method is to add the letter "W" after the machine number.

BX silencing fans are divided into: BX1、BX2。

The BX1 fan casing does not come with a muffler, but the inlet and outlet are equipped with mufflers; The BX2 type fan is equipped with mufflers on the exterior and inlet/outlet ports. The length of the muffler is 500mm, 750mm, 1000mm, and 2000mm; Users can customize the length according to their needs.

Fans can be customized into explosion-proof types according to environmental requirements.

working conditions

Product Application

Fans can be widely used in ventilation and air exchange places such as high-rise buildings, industrial and mining enterprises, hotels, restaurants, museums, sports halls, underground garages, etc. It is a preferred series for pipeline pressurization, air supply and exhaust, as well as ventilation and air exchange in high-rise or general buildings.

Fan configuration

Standard configuration:

Impeller, casing (air duct, guide vanes, inner cylinder, motor bracket), motor, feet, etc.

Optional parts and accessories (indicate whether purchased when ordering):

Muffler, vibration reduction equipment, dedicated electrical control box, mesh cover, docking flange.

Processing technology

The fan impeller is made of steel, the hub is hydraulically stretched and formed, the blades are hydraulically formed after stamping, and the blades are welded and assembled with the hub. The impeller has undergone static and dynamic balance correction, and the balance accuracy is not greater than G5.6 level.

The outer cylinder flange is made by integral flanging and spinning. In order to maintain consistency with the installation size of the user, the company's products will not drill holes on the flange unless otherwise specified by the user.

Wind vent muffler (optional) mold hydraulic/flanging and spinning forming. The inner layer is made of galvanized sound-absorbing microporous plate, and the interlayer is made of high-temperature resistant sound-absorbing cotton.
