 CALT LGCD-355II Diesel Portable Compressor: Frequently Asked Questions (FAQ)
High-power electronics like 355 kW can cause grid harmonics. How does AIRERA solve the power pollution problem for factories?
Large-scale electrical equipment can inject harmonic noise into a factory's power grid, potentially disturbing sensitive CNC machines or automated testing lines. AIRERA’s 355 kW intelligent electronic control system is equipped with built-in heavy-duty DC reactors and advanced EMI filters as standard. It suppresses harmonic interference at the source, ensuring compliance with strict international power standards. It delivers an ultra-clean startup and running profile that fully protects the factory’s grid stability and sensitive downstream electronics.
Heavy industries like cement, steel, and mining are often dusty. How does AIRERA 355 kW maintain its "maintenance-free" pledge under such harsh conditions?
Harsh environments are the ultimate test for large compressors. AIRERA’s 355 kW model features an IP55/IP56 fully enclosed motor and a dust-proof, heavy-duty electronic control cabinet with independent cooling channels. Because the direct-drive design replaces belts and gears, there are no open drive components where abrasive dust can gather and cause wear. Combined with a multi-stage heavy-duty air filtration system, it keeps internal components pristine, ensuring true "maintenance-free" peace of mind even in dusty or humid heavy-industrial environments.
Can the AIRERA 355 kW compressor's smart control adapt to specific customized pressure and flow requirements for special processes?

Absolutely. Different industrial processes require varying target pressures (e.g., 7 bar, 8 bar, or 10 bar). AIRERA’s intelligent control system allows for stepless target pressure setting with an accuracy of up to $pm0.01text{ MPa}$. Instead of letting the machine over-pressurize—which wastes huge amounts of power—the smart system regulates the direct-drive air end to produce the exact volume and pressure required by the specific recipe, allowing the compressor to seamlessly blend into high-precision, customized production lines.
