High-Efficiency Screw Rotor for Maximum Performance

The core component of the Kimair portable electric air compressor—the compression main unit—features imported screw rotors that undergo precision grinding and male-female rotor pairing assembly to ensure exceptional working efficiency. These rotors are designed with an advanced profile that integrates with sealing grooves, achieving excellent sealing performance and minimizing leakage, thus guaranteeing stable and sufficient air supply.

Additionally, the Kimair compressor incorporates an innovative BFR (Lubricating Oil Reservoir) System, utilizing a pressure overflow lubrication method to ensure optimal lubrication of bearings and screw rotors, significantly extending service life. The large-diameter rotor enhances load-bearing capacity, while the low-speed matching design reduces noise and vibration, further improving overall machine reliability and stability.

Advanced Energy-Saving Intake System

The Kimair portable electric air compressor is equipped with an advanced and energy-efficient intake system. Its large-diameter, low-pressure-drop design optimizes intake efficiency, enabling the unit to operate efficiently under various working conditions. The integrated combination intake valve incorporates a check valve, vent valve, and unloading valve, simplifying the control circuit layout for a streamlined design that reduces maintenance costs.

The adoption of a butterfly valve ensures smoother operation during light-load startup and prevents oil backflow into the main unit during sudden shutdowns, eliminating the risk of contaminating the air filter element. Additionally, the instant-response capacity regulation system maximizes energy efficiency based on the user’s operational needs, achieving significant energy savings.

Superior Lubrication and Air Separation System

The lubrication and air separation system of the Kimair portable electric air compressor also delivers outstanding performance. The specially designed internal structure of the separator tank achieves an initial separation efficiency of over 99%, ensuring that the oil content in the discharged air remains below 3 ppm, meeting the stringent requirements of industrial applications.

The customized pleated oil separator element, made from imported German materials, features a large filtration area, minimal pressure loss, and extended service life. Additionally, the high-precision oil filter from a renowned brand ensures exceptional filtration efficiency, effectively protecting the main unit for long-term reliable operation. The secondary oil return system is equipped with an oil sight glass, allowing users to monitor the separation effect in real time, ensuring the stability and reliability of the entire compressor system.

Humanized Design and Safety Protection

The Kimair portable electric air compressor excels in user-friendly design and safety protection. The intuitive control panel allows users to easily monitor the operating status of the unit and perform relevant operations with ease. The fully enclosed electrical control box is dustproof and moisture-resistant, ensuring the stability and reliability of electrical components.

The segregation of high- and low-voltage zones enhances safety during maintenance. The waterproof, dustproof, wear-resistant, and anti-bending design ensures a safer and more convenient power connection for users. The four-wheel steering chassis is robust and highly maneuverable, making it safer for use on construction sites, while the integrated braking system further ensures both operational and parking safety.

The outer cover is made of cold-rolled steel plate and has been treated with outdoor anti-ultraviolet powder electrostatic spraying, with excellent anti-rust performance. The built-in high-efficiency sound-absorbing cotton effectively reduces the noise of the whole machine, creating a more comfortable working environment for users. The lift-up side door design provides a good space for maintenance, making it convenient for users to conduct regular inspections and maintenance of the unit.
