●  Complete Cooling & Lubrication System: 1.6L large-capacity pump lubricating oil design, with independent large-area cooling net, efficient heat dissipation during long-time full-load operation.

●  Dual-Pressure Automatic Control: Automatic cut-in pressure at 9Bar, automatic stop at 12Bar, realizing intelligent automatic pressure control.

Expert Advice

●  Daily Maintenance: Check pump lubricating oil level regularly, maintain oil volume at 1.2-1.6L; replace special air compressor oil every 500-800 working hours; clean cooling net and air intake filter weekly.

●  Pressure Operation: Factory preset cut-in pressure 9Bar, max working pressure 12Bar; do not adjust pressure switch to exceed factory settings to avoid overload damage.

●  Power Supply Requirements: Must use 380-400V three-phase stable power supply; for power cables longer than 20 meters, use thicker-diameter cables to ensure starting voltage stability.

●  Operating Environment: Use in well-ventilated open-air or semi-open industrial areas; avoid high-temperature, dusty and humid closed environments.

●  Belt Inspection: Check belt tension and wear monthly; adjust tension in time, replace worn belts to prevent slipping and power loss.

●  Condensate Drainage: Drain condensed water from the tank bottom drain valve every 2-4 hours during continuous heavy-duty operation to prevent internal corrosion of the air tank.

●  Duty Cycle & Cooling: Under full-load 12Bar high-pressure mode, allow a 15-minute cooling break after every 40 minutes of continuous operation to protect pump and motor.

●  Mobility Safety: Depressurize the tank below 1Bar before moving; ensure the ground is flat and stable during transportation.

●  Storage Guidelines: Depressurize the tank completely, drain all moisture, clean pump and cooling net, store in a dry, dust-free and well-ventilated warehouse.
