Customer Frequently Asked Questions (FAQ)

Q: What is the ROI of the ELV series?

A: As a premium solution, the ELV has a higher initial investment. However, its energy-saving performance in ultra-large, low-pressure, variable-load systems is remarkable. Under high-load operating conditions, the incremental investment is typically recovered through electricity cost savings within 1.5 to 3 years, delivering outstanding long-term financial returns.

Q: With such high flow rates, how is supply stability and air purity ensured?

A: Stability is ensured by the precision inverter control system and robust two-stage airend. For air purity, the ELV provides clean compressed air. Depending on process requirements, downstream equipment such as KIMAIR dryers (e.g., KDR series) and filters (KYF series) can be added to form a complete low-pressure purification system, guaranteeing air quality.
