Permanent Magnet Variable Frequency Air Compressor Delivers Food-grade Clean Air for Brewing Industry

The fermentation and filling procedures of liquor production set strict standards on oil content and cleanliness of compressed air, which must comply with food hygiene regulations.

The production base deployed 75kW permanent magnet variable frequency twin-screw air compressors, matched with precision filters and multi-stage purification devices.

The oil content of output compressed air is measured at 0.007mg/m³, fully meeting food-grade requirements. The variable frequency mode adapts to fluctuating air demand, lowering energy consumption by 28%. Consistent air supply maintains stable fermentation conditions and improves the taste uniformity of finished products.
