This series of products is known for high reliability, energy conservation, environmental protection, and low maintenance costs, and is suitable for medium and high voltage application scenarios.
Core Features:
Efficient fixed frequency motor
The Grandenford fixed frequency series air compressor is equipped with a three-phase asynchronous motor and gear direct drive, and the motor complies with the IEC60034-30 standard lE3 energy efficiency level.
The main motor is carefully selected according to the needs of the air compressor application. Both torque and load can meet special requirements
Design standards to optimize motor efficiency and power coefficient under load conditions. This optimized coefficient has an efficiency advantage of approximately 5% compared to other motors.
Motor frame
The frame and end caps of the motor are made of cast iron and aluminum castings. This provides a more secure support for the bearings, ensuring even clearance between the rotor and the spindle, and ensuring that the coupling components used are permanently parallel and flange like.
Electrical design
The design speed, torque, and operating parameters all meet the load requirements of the compressor. The motor efficiency and power coefficient have reached the ideal level, which can meet the air volume requirements of GDK series air compressors.
Bearing
The vacuum exhaust bearing at the drive end and the roller bearing at the exhaust end provide strong support for the operation of the air compressor. The average usage time of these oversized bearings is 135000 hours, which is approximately 8 times the NEMA standard. These two types of bearings are cooled by the coolant flowing through the bearing groove, simplifying the lubrication process.
Insulation material
The GDK series high-efficiency motor adopts F-class insulation and B-class temperature rise. Under continuous load conditions, the maximum allowable ambient temperature can reach 155 ℃. Temperature is crucial for the lifespan of an engine, and this special consideration makes the GDK series motors more reliable, have a longer service life, and better adapt to harsh environments.
Protection grade
The GDK series high-efficiency motor adopts a closed motor with an IP55 protection level, effectively preventing dust and moisture from entering the motor, ensuring that the motor can work normally even in harsh environments.
Host
The host is the core part of the screw air compressor. The original intention of the host design is to ensure reliable quality, stable performance, and high operating efficiency, which not only reduces manufacturing deviations but also enables precise installation of the host. And some other components in the air compressor provide important support and control for the reliable operation of the host. The GDK90-160 series adopts a newly designed high-efficiency host, with an average energy efficiency improvement of over 10%, and achieves long-term reliable operation.

Transmission mode
The motor and host of the GDK permanent magnet frequency conversion series products adopt a coaxial direct drive system, which is a more effective, reliable, and robust design. Coaxial transmission reduces mechanical losses of equipment such as belts and gears. Coaxial connection method results in higher transmission efficiency. Simultaneously maintaining permanent coaxiality, the machine base is completely sealed to prevent impurities in the air and ensure smooth power transmission.
Efficient cold air intake system
intake filter
The efficiency of the intake filter is as high as 99.5%, with an accuracy of over 3 microns. The intake filter and intake valve are directly connected, making replacement more convenient; The intake valve integrated with solenoid valve reduces pipeline connections, minimizes leakage points, reduces intake resistance, increases suction efficiency, and improves compression efficiency.
Efficient nano coated air filter with high filtration performance, targeting 0.3um, which is more than three times that of ordinary filter materials.
Independent cold air intake channel
GDK has newly designed an independent cold air intake channel, which has a lower intake temperature, larger air volume, lower pressure drop, and greatly improves the efficiency of the host.
Reduce the exhaust temperature of the entire machine, extend the service life of the pipeline, and greatly improve the performance of the cooler.
Cooling system
The GDK series adopts an independent arrangement of oil coolers and aftercoolers. Compared with the traditional welded cooler arrangement, it avoids the failure of the cooler caused by thermal stress concentration at the weld seam due to the different expansion coefficients of cooling oil and compressed air, and extends the service life of the cooler. Replacing the cooler is more convenient, saving customers' usage and maintenance costs.
- Independent air duct design for oil cooling and rear cooling - subverting the traditional parallel design mode, installing oil cooling and rear cooling separately on two sides, fundamentally eliminating the influence of thermal stress and thermal expansion
- Side installation, compared to top installation, has higher after-sales maintenance efficiency
- The air duct is completely independent, reducing the power consumption of the fan while ensuring that the core components can achieve the desired cooling effect
- The synchronized cooling of the internal components of the unit through the rear air duct not only cools but also provides sound insulation and noise reduction for the entire machine
- Large margin aftercooler,<10 º C CTD (air-cooled&water-cooled), can adapt to relatively harsh environments, ensuring normal operation of the entire machine at an ambient temperature of 46 º C
Cooling fan
The fan adopts a star delta control logic to reduce the frequency conversion power. Three fans are linked for control, improving the energy efficiency of the unit and ensuring cooling performance
The oil cooled fan is installed diagonally above the cooler, ensuring cooling air flow while greatly saving unit space; The tilt angle has undergone rigorous FEA simulation to ensure better cooling effect
The cooling fan can be slid along the lower slide rail for maintenance, which can be easily operated by one person, greatly improving the efficiency of fan after-sales service
Reduce the suction temperature on the surface of the cooler, distribute the air evenly on the surface of the cooler, and improve the cooling and heat transfer efficiency; Compared to blowing cooling methods, suction cooling has no dead corners and better cooling effect
Pipe system
- All connecting components in key areas are sealed with fluorine rubber O-ring end faces
- The possibility of leakage is almost completely eliminated, and the connection can be repeated infinitely
- Eliminating the axial clearance required for typical sealed connections
- chemical resistance
The O-ring seal is a more effective sealing structure that prevents oil leakage according to the standards of the American Association of Automobile Manufacturers. Compared with typical threaded connection seals, this advanced sealing method eliminates axial clearance, is easy to install, and the connecting parts will not deform due to tight fixation, fundamentally improving the leakage prevention level.
The whole machine adopts the same flange design - reducing vulnerable parts and facilitating maintenance.
High temperature resistant unit components - including intake solenoid valves, pipelines, electronic components, etc., all meet the high temperature resistance standard of over 100 º C.
