From June 9 to 11, 2026, the annual international chemical equipment conference – 2026 China International Chemical Equipment Expo (CTEF) will be held at the Shanghai New International Expo Centre.

Shandong Zhangqiu Blower Co., Ltd. will showcase its cutting-edge equipment and products. We welcome domestic and international industry colleagues to visit our booth for exchange, discussion, and procurement cooperation at Booth No. E2075.

Company Profile

Shandong Zhangqiu Blower Co., Ltd. was founded in 1968, boasting over 50 years of experience and technology in blower design, production, and manufacturing. The company has successively established two Sino-Japanese joint ventures and set up a subsidiary in the United States, becoming the first company in China's blower industry to establish a branch abroad at that time. Through continuous development, Zhanggu has grown into a modern-scale machining enterprise integrating the design, production, and sales of Roots blowers, centrifugal blowers, industrial pumps, fans, industrial water treatment engineering and equipment, pneumatic conveying systems, electrical equipment, and MVR evaporation concentration & crystallization systems. The industrial park covers an area of 430,000 square meters, providing vast space for the company's leapfrog development and partnerships with enterprises worldwide. The company was successfully listed on the Shenzhen Stock Exchange on July 7, 2011, with the stock code: 002598, marking another new milestone in its development history.

The company's products are widely used in industries such as papermaking, environmental protection, pharmaceuticals, energy, chemical, metallurgy, iron and steel, power, and textiles.

Air Bearing High-Speed Centrifugal Blower

The air bearing high-speed centrifugal blower is a high-efficiency, energy-saving, and environmentally friendly product. It features a simple mechanical structure, few moving parts, robust control performance, and easy maintenance. It utilizes automotive-grade, oil-free, highly reliable hydrodynamic air bearings, ensuring frictionless operation and minimal mechanical loss. Employing advanced permanent magnet synchronous motor technology, it can reach a maximum speed of 95,000 rpm and achieve full speed in just 5 seconds. The motor efficiency is as high as 97%, meeting the Dual-Level 1 Energy Efficiency Standard.

The blower uses a wide-operating-condition, highly efficient 3D-flow impeller, overcoming key technologies in low specific-speed design for high efficiency. The integrated special design of the main unit keeps noise below 75 dB(A) and vibration under 12 μm. Featuring stepless regulation, the blower can start and stop quickly, with continuous start-stop cycles exceeding 200,000 times.

MC Series Multi-Stage Centrifugal Blowers

The MC series multi-stage centrifugal blowers are high-efficiency products developed by our company with introduced American technology, representing advanced world-class levels. This product incorporates multiple proprietary and patented technologies, offering low noise, low vibration, and high efficiency, with significant performance advantages over domestic products.

Key Features:

1.Bearing housing adopts a dual-oil-chamber design to prevent oil foaming.

2.The blower utilizes an air-cooled structure, eliminating the need for cooling water.

3.An inlet guide ring is fitted at the impeller inlet for high aerodynamic efficiency.

4.Easy installation without the need for foundation bolts.

Magnetic Bearing High-Speed Centrifugal Blower

The magnetic bearing blower is a new, highly efficient, energy-saving, and environmentally friendly product. It is an integrated design based on traditional blowers, incorporating active magnetic bearing technology and high-speed permanent magnet synchronous motor technology. Its core technologies include magnetic bearings, 3D-flow impellers, high-speed permanent magnet synchronous motors, high-efficiency inverter speed control, and intelligent monitoring and control. It starts by levitating first and then rotating, ensuring frictionless operation, no need for lubrication, and maintenance-free service. The 3D-flow impeller is directly connected to the shaft, resulting in zero transmission loss, making it a high-tech, green, and energy-saving product.

Centrifugal Fans

The centrifugal fans for the petrochemical industry offer the following advantages:

1.Designed using 3D fluid dynamics theory, they achieve high aerodynamic efficiency, meeting the National Grade 1 Energy Efficiency Standard.

2.Systematic simulation and structural optimization are performed using the proprietary CAE software SiPESC, ensuring excellent operational stability.

3.Verified through strength, vibration, and modal tests, guaranteeing superior mechanical performance and high reliability.

4.Unique lightweight rotor design facilitates easy starting and low overall energy consumption.

5.The fan adopts an integrated skid-mounted structure with the industry's highest balance grade of G1.0, where bearing vibration is ≤2.5 mm/s. The fan features an aesthetically pleasing structure, convenient installation, and low noise, achieving international advanced levels.
