Core Features & Advantages

Inline Dust & Powder Filtration System

Inline Dust & Powder Filtration System

Positioned directly upstream of the vacuum pump to intercept fine airborne particulates, chemical powders, and food dust during rapid evacuation, effectively safeguarding the vacuum pump against clogging and premature wear.

PLC Touchscreen & Emergency Safety System

PLC Touchscreen & Emergency Safety System

Intuitive touchscreen interface allows operators to precisely program vacuum duration, heat seal timing, and cooling cycles with recipe recall. Integrated with an emergency stop push-button for safe setup, rapid adjustments, and protected operation.

Adjustable Height Bag Support Baffle

Adjustable Height Bag Support Baffle

The internal support baffle features flexible height adjustment to perfectly adapt to varying pouch heights and fill levels (10kg to 50kg), ensuring upright stability and clean hermetic seal alignment.

Square & Drum Mold Vacuum Shaping

Square & Drum Mold Vacuum Shaping

Accommodates custom square brick-forming molds or cylindrical drum containers, drawing pre-filled bulk bags (10kg to 50kg) directly into tight, uniform shapes for optimized pallet stacking and logistics.
