Oil-Free Airfoil Bearing Turbo Blowers and Turbo Compressors

 

Centrifugal Air Compressors and Blowers from 3HP to 1,200HP, Air or Water Cooled

LPR Global offers high-speed centrifugal oil-free turbo blowers and fuel cell turbo compressors. Our air compressor models range from 3HP to 1,000HP and cover air pressures from 0.6 kgf/cm² up to 9 kgf/cm² (9 bar) with single or dual motors and multiple compression stages. We offer models with a single impeller to twin and two-stage impellers suitable for larger pressure requirements and medium to high airflow. 

 

Our turbo blowers come in single, dual, and twin types, ranging from 10HP – 1200HP, with airflows and pressures up to 176cfm and 29,664psi respectively. Our micro turbo compressors have an operating range of 3HP – 25HP and 1.6 – 2.5 bar which are designed for fuel cell applications and can be used in various industries. Our blowers and compressors use Permanent Magnet (PM) motors with a maximum efficiency of 95%, enabling speeds from 20,000 to 220,000 RPM. 

 

A patented dual cooling system (air or water) lowers motor temperature by up to 10 degrees Celsius compared to conventional compressors and allows for efficient, low-maintenance, and compact turbo machines. The frictionless characteristic of the oil-free air foil bearing improves durability and minimizes maintenance. We also offer API-specified turbo compressors suited for oil and gas and petrochemical applications.

Oil-Free Airfoil Bearing Turbo Blowers and Fuel Cell Turbo Compressors

We offer oil-free, contactless airfoil bearings that are frictionless in operation, resulting in reduced noise and vibration, extended bearing life, and less maintenance. For standard operation, only an air filter replacement is required every 3 months depending on operational condition. No lubrication is required.

Our products are 100% oil-free due to the application of air foil bearing technology.

 

 

Manufactured by the South Korean leader in turbo blower technology, high speed turbo blowers are produced following ISO9001:2015, ISO14001:2015, UL Certification, CE, NRTL, ATEX, High Efficiency Equipment Certification, Certificate of Gas Leak Prevention, IECEx Certificate required for the use in potentially explosive atmospheres such as petroleum stations and oil refineries, ASME certification, ASME U, and EAC standards and certifications.

Overall efficiency of high speed turbo blowers mainly depends on their design. Air flow, pressure, and speed (RPM) are affected by the impeller shape, cooling system, and internal structure of the blower.

 

We have accumulated a number of patens for ground-breaking design of impeller and dual motor cooling system.

Lowering the motor temperature is critical to determine blower efficiency, our dual motor cooling system features a patented two stage motor cooling system that lowers motor temperature by more than 10 degrees (C) compared to other brands. The design allows for cool air to reach stator, bearing, winding, and rotor. The heated air is exhausted outside of the enclosure.

 

The patented high-efficiency supersonic impeller uses both axial and radial compression and has a large diameter for maximum efficiency. It is made from high strength aluminum alloy (AL7075- T651) that processed up to 0.001mm thickness. Impeller is hard anodized for corrosion prevention and chemical resistance to perform in aggressive environments. Compressor system is designed to be directly connected to the rotor without any coupling, resulting in zero efficiency loss while maintaining structural stability and balance altogether. We also offer stainless steel and titanium impellers for higher fatigue applications.

 

Air flow of our turbo blowers and turbo compressors is controlled by VFD (Inverter) and the main controller. VFD allows change of the frequency rate to the desired point that the system has to operate at. This is achieved by the PLC or MICOM controller depending on the user’s preference. Available PLC options include Allen-Bradley, GE, SIEMENS, OMRON, RS-AUTO or LG. The control panel can be connected remotely to plant SCADA via Ethernet, RS485 or RS422. PLC controls the overall performance including the amount of pressure, air flow, RPM, etc. Operator can set up a specific percentage value to achieve the desired rate and air flow volume this way avoiding energy loss. Our bell-mouth flow meter can measure the flow within ± 0.5% tolerance (JIS B 8340).

Oil-Free Energy Efficient Dynamic Centrifugal Compressed Air Products

Energy efficiency and smaller carbon footprint are the primary drivers of aeration blower technology selection. Reduction of energy consumption is the deciding factor for utility system design. Operating variables such as air flow control, plant set up, and other operational settings can significantly affect cost and benefits of blower aeration systems.

 

This is especially important for the water and wastewater industries where energy required to produce air accounts for about 60 per cent of the total energy consumption of a wastewater treatment facility.

 

For applications requiring high air flow and low energy consumption, high speed turbo blower provide valuable features including wider operating range, higher efficiency, lower noise, lower vibration, lower maintenance cost, and longer life cycle.

We offer a large inventory of high speed turbo blowers and compressors with a vast range of performance levels for medium and high pressure ranges, all ready for immediate use and suitable for harsh environments.
