Turbo Blower

Product Description

Performance and energy efficiency are both ‘best in class’.

Samjung Turbine SJT-H series is high-efficiency turbo blower adopting inverter of high speed motor (BLDC) and hybrid bearing.

It is more efficient than the existing products, and the noise and vibration are less, so you can revolutionize your work environment. In addition, the installation area is small and the air volume control range (30 ~ 100%) is widened, which enables reasonable energy saving.

World’s largest airflow range and full range of energy savings

‘best in class’

By controlling the combination of inverter and variable discharge diffuser, the efficiency is high and the air volume range is 30 ~ 100%, and high energy saving effect can be obtained at any point within the control range.

Flow Control Range	30%	40%	70%	100%
Aerodynamic Efficiency	Over 70~80%	Over 80%	Over 84%	Over 84%

Outstanding performance

Superior compression efficiency

Patented hybrid bearings maximize aerodynamic efficiency by minimizing the gap between the impeller and shroud. (Air bearings are difficult to minimize gap between impeller and shroud (Tip clearance) due to their characteristics, resulting in loss of 5-9%)

Outstanding motor performance

Patented Technology Simultaneously Cooling the Motor Stator and Rotor Large diameter motor Rotational phase High torque and high efficiency.

Due to the patented rotor structure, the gap between the stator and the rotor is narrow and the efficiency is high.

Customized high efficiency impeller, scroll ‘best in class’

Unlike conventional standard model production maker, it produces the highest aerodynamic efficiency by making impeller (5-axis machining) and scrolling (casting) according to customer’s specification (Pressure x Flow Rate).

Vertical High Speed Rotor Application

- The high efficiency of rotor due to narrow gap between rotor and stator due to sag and thermal deformation of high speed rotor –

- Combined control system with inverter and variable discharge diffuser Turn-Down Ratio: 30 to 100%

Diffuser System

It operates in combination with the inverter to provide a wide range of flow rates, as well as high efficiency over the entire flow range.

Patented Diffuser System

The patented Diffuser System was installed at the back of the impeller to maximize the airflow range by using the check valve and the windshield valve as a substitute for the damping noise.

– Air flow control range: 30 ~ 100%
