Summary & Buyer Guidance

When sourcing a rotary screw air compressor in China, consider these key criteria:

• Power & duty cycle: What motor size, air flow, pressure do you need?

• Technology: Fixed-speed vs VSD vs permanent magnet? Oil-injected vs oil-free?

• Energy efficiency: Does the manufacturer offer claims of energy saving (e.g., 30 %+)?

• Brand & support: Established brand or emerging supplier; spare parts availability; export track record.

• Application fit: For smaller workshops (Sollant), large industrial plants (Kaishan), high-quality/critical air (Fusheng), advanced tech (SCR), budget/new supplier (QiAir).
