AIRERA 250kW Screw Air Compressor: Frequently Asked Questions (FAQ)
What are the technical advantages of the 250kW direct-drive system when handling ultra-heavy production loads?
This system utilizes a high-strength flexible coupling to connect the motor directly to the large-displacement air end. Not only does this eliminate the energy loss found in belt drives, but it also provides higher torque transmission precision and operational stability at a 250kW power output. This structure significantly reduces the number of wearing parts, ensuring smooth operation even under the extreme loads of large-scale industrial sites.
How does the oil-injection system help extend the lifespan of a high-power machine like the 250kW model?
In the 250kW class, controlling the temperature rise of the air end is critical. AIRERA’s precision oil-injection circulation system uses three-stage filtration and high-pressure injection to form a dense oil film within the compression chamber. This provides excellent cooling and sealing while offering superior bearing lubrication, significantly reducing mechanical wear on the large-scale rotors during high-speed operation.
Is the long-term maintenance of a large-scale 250kW unit complicated?
Not at all. AIRERA considers the maintenance convenience of heavy equipment by employing a spacious door-opening structure and a centralized layout for service points. Since there are no belts to tension or replace, maintenance is primarily focused on the periodic replacement of filters and oil. All consumables are designed for an extended service life to minimize downtime to the greatest extent possible.
