Rotary Blower

Brief Introduction for ZMR、ZMH Series Compact Rotary Blower

The ZMR/ZMH series compact rotary blower unit was newly developed by our company. Rotary blower, inlet silencer (including air filter), outlet silencer, relief valve, pressure gauge, check valve, flexible joint, vibration isolator are integrated. The rotary blower in the ZMR series unit adopts the RR series blower with two lobes which technology is from Japan. The ZMH series compact rotary blower unit adopts the 3H series rotary blower with three lobes which was developed by our company and has several patents.

Product Features:

• A wide range of capacity and pressure is available. Capacity 0.45-100.6 m³/min; Pressure 9.8-98 kPa.

• Noise is low. Noise-lowering profile and structure are applied, gear accuracy is the fifth class, bearings are imported, and main parts are NC machined. So, the blower can run for a long time reliably.

• Low vibration and low noise due to accurate dynamic balance.

• The air pulsation is low and runs smoothly.

• The transported air is clean and free of oil and dust. Oil lubrication is not needed in the casing, special structure is designed to prevent the bearing oil and gear oil entering the casing.

• Simple structure, little outline, light weight.

• Installation is convenient and not needing anchor bolts.

Application:

Widely used in sewage treatment, pneumatic system, aquatic farming, power, cement, etc. fields.

Product Advantages

A full spectrum of capacities and pressures is offered, ranging from 0.45 to 100.6 m³/min and 9.8 to 98 kPa, respectively.
Designed for quiet operation, the blower incorporates low-noise profiles and structural features. It is equipped with fifth-class precision gears, imported bearings, and CNC-machined core components, ensuring long-term reliable performance.
Vibration and noise are minimized through precise dynamic balancing.
The unit operates smoothly with minimal air pulsation and delivers clean, oil- and dust-free air. Thanks to its specialized sealing structure, no oil from the bearings or gears enters the air chamber, eliminating the need for internal lubrication.
Its compact and simple design makes the blower lightweight and space-efficient.
Installation is straightforward and requires no anchor bolts.

The ZG Series Roots Blower is an upgraded product independently designed and developed by our company, based on advanced American blower technology and enhanced with our proprietary innovations. It represents a world-leading technology with the best cost-performance ratio available today.

Product Features:

1. The ZG Series adopts a specially designed housing structure, ensuring reliable operation under high pressure while reducing operating noise.

2. The impeller and shaft are cast as an integrated unit, providing excellent rigidity to ensure stable operation at high speeds with large flow and high pressure.

3. The blower oil tank is made of aluminum alloy with an air-cooled structure, eliminating the need for water cooling even under a single-stage pressure of 98 kPa.

4. The compact unit design features a self-tensioning belt system, making use and maintenance convenient.

5. The main unit can be installed either vertically or horizontally, allowing easy replacement of foreign models.

6. Equipped with precision helical synchronous gears with hardened surfaces and keyless connection, ensuring reliable positioning, smooth operation, low noise, high strength, and long service life.
