Customer Frequently Asked Questions (FAQ)

Q: How much more electricity does a permanent magnet variable frequency air compressor save compared to a standard variable frequency air compressor?

A: The savings vary depending on operating conditions. In typical variable load applications, the PS series PM motor inverter rotary model can achieve an additional 8%-15% energy savings compared to asynchronous motor variable frequency models. Compared to fixed-speed industrial frequency models, the comprehensive energy saving rate typically exceeds 30%-40%.

Q: Is the maintenance cost of the PS permanent magnet model the same as ordinary machines?

A: Routine maintenance items (air filter, oil filter, oil separator, lubricant) are largely the same. Due to its excellent thermal balance and soft start characteristics, mechanical wear on the airend and bearings is reduced. In the long term, the failure rate and replacement cycle of key components are better than ordinary models, resulting in a more advantageous overall maintenance cost.

Q: Can permanent magnet motors demagnetize? How reliable are they?

A: KIMAIR uses high-performance, high-temperature-resistant rare earth permanent magnets and strictly controls the motor operating temperature within the design range. Under normal operating conditions, the lifespan of the permanent magnets matches that of the airend. Our motors undergo rigorous durability testing and come with a long-term warranty for peace of mind.

Q: Is multi-unit control and remote management supported?

A: Yes. The PS Series can be seamlessly integrated into the KIMAIR AIRMATICS intelligent control system, enabling multi-unit coordination, cloud data monitoring, energy efficiency analysis, and predictive maintenance, allowing for the easy construction of an intelligent compressed air station.
