300L Heavy-Duty Electric Air Compressor
Engineered for industrial workshops, commercial automotive garages, and manufacturing facilities, this 300L Electric Air Compressor delivers high-volume compressed air for heavy continuous duty. Powered by a high-torque electric motor and a cast-iron belt-driven pump, it provides high airflow delivery to run multiple pneumatic tools simultaneously. Featuring a large 300-liter air receiver tank, dual pressure gauges, and safety shut-off valves, this unit delivers reliable pressure maintenance and low operational noise for demanding workshop environments.
Key Features & Operational Advantages
High-Capacity 300L Air Receiver: Large-volume pressure tank minimizes motor start-stop cycles, reducing mechanical wear and ensuring a steady, uninterrupted airflow.
Heavy-Duty Belt-Driven Pump: Features a cast-iron cylinder pump with low operating RPM, maximizing heat dissipation and extending unit operational lifespan.
Dual-Outlet Pressure Control: Equipped with an integrated pressure regulator, dual output quick-connect couplings, and clear pressure gauges for precise line-pressure adjustment.
Automatic Pressure Switch & Thermal Safety: Features an automatic start/stop pressure switch and built-in thermal overload protection to prevent motor overheating.
Reinforced Chassis & Dampening: Built with heavy-gauge steel legs and rubber vibration-isolation mounts to reduce operational noise and movement during operation.
Easy Maintenance Access: Outfitted with an accessible oil drain plug, sight glass for easy oil level monitoring, and a bottom tank drain valve for routine moisture purge.
