What is the filtration precision of the intake system?

It utilizes a nano-scale filter layer that reaches 99.99% efficiency, ensuring only the cleanest air enters the compression chamber.

How do I manage the "Random Password" security feature?

Upon startup, a unique code is displayed. Simply provide your name and plate info to our service team via the designated channel to receive y

Is the VFD protected against harsh environments?

Yes, the inverter is treated with anti-dust, anti-moisture, and anti-mold coatings (three-proof paint) and includes built-in lightning protection.

Can I connect multiple units for centralized control?

Yes, the Modbus 485 protocol allows multiple GDK90 units to be linked to a central host computer for efficient group management.

What are the installation requirements?

The GDK90 features a compact footprint. It requires a stable foundation, proper ventilation (as per our airflow design), and power connection matching the 90

Key features

Hybrid Permanent Magnet (HPM) Motor: Utilizes advanced oil-cooled HPM technology, achieving 5-10% higher efficiency than traditional induction motors by eliminating rotor excitation losses.

Level 1 Energy Efficiency: Certified for the highest energy-saving standards, ensuring the lowest specific power consumption in its class.

Integrated Coaxial Direct Drive: The motor and airend are coaxially connected without belts, gears, or couplings, resulting in 100% transmission efficiency and enhanced structural rigidity.

Intelligent VFD Energy Saving: Automatically adjusts motor speed based on real-time air demand, eliminating no-load energy waste and maintaining precise pressure within 0.01 MPa.

Ultra-Reliable Intake Valve: Tested for over 5 million cycles, featuring a normally closed structure with low pressure drop and sensitive response for safe starts.

Advanced Nano-Filtration: The air filter uses a unique nano-filter layer, achieving a filtration efficiency of 99.99%, effectively protecting the airend from microscopic contaminants.

Soft-Start Technology: The VFD acts as a soft-starter, keeping the starting current below 2x the rated current, protecting your power grid and mechanical components.

Optimized Airflow & Cooling: Side-intake and top-exhaust design rapidly removes radiant heat, ensuring stable operation even in ambient temperatures up to 45 degree Celsius.

Smart Multi-Language Controller: Features a high-definition display supporting English, Chinese, and Korean, with Modbus 485 protocol for seamless IoT integration.

Whisper-Quiet Operation: Low-frequency running and optimized internal structure significantly reduce mechanical noise, creating a better working environment.

AI-Powered supplier vetting

SummaryKopa Trading (Shanghai) Co., Ltd. is a China-based limited company established in 2016, focused on compressors, air compressors, blowers, refrigeration equipment, and related maintenance and mechanical-electrical products. It has valid import/export licensing, six years of export experience, and exports 41%–50% of total sales, mainly to South America and Europe. The supplier reports flexible customization, five years of total R&D-engineer experience, and 41–50 quality-control staff, but has one production line and does not conduct continuous quantity reconciliation for each batch. Finished products are checked by packing staff. No SDK is available, while certification holdings, customer cases, after-sales capability, and several sustainability-related conditions are not evidenced. Financial records are referenced for 2021–2023, but the supplied information does not provide sufficient financial-performance detail for a credibility judgment.

Supplier typeThe supplier is a China-based limited company established in 2016, with a combined company type, an affiliated company, and business activities covering compressor design, production, sales, equipment maintenance, and related mechanical-electrical products. Its stated product range includes rotary screw, oil-free, centrifugal, scroll, and blower equipment.

R&D capabilityThe supplier reports five years of total R&D-engineer experience and describes efforts to improve compressor efficiency and reduce energy consumption. However, it explicitly has no available SDK, and the slices provide no details on patents, dedicated R&D resources, product-development results, or innovation projects.

Production capacityThe supplier reports one production line and annual production output in the stated range, with 41–50 quality-control staff. A deficiency is explicitly identified in that the factory does not continuously reconcile quantities for every batch or mass-production run; finished products are checked by packing staff, indicating a limited documented inspection method.

Customization capabilityThe supplier explicitly reports flexible customization capability, directly supporting its ability to adapt products or services to customer requirements. No further limits on customization scope, engineering process, or delivery performance are provided.
