OY1007 Large-Capacity 4.5L Steel-Reservoir Air Pump

The OY1007 Large-Capacity 4.5L Steel-Reservoir Air Pump is the highest-volume model in its pneumatic hydraulic pump family, providing 4.5 litres of usable oil capacity in a robust steel-body construction for applications that demand extended, uninterrupted hydraulic operation without reservoir refilling. With a 10,000 PSI rated pressure output and an air input requirement of 0.4 to 1.0 MPa, it delivers consistent high-pressure performance through its 3/8"-18NPT output port.

The steel reservoir construction provides mechanical durability and resistance to impact damage, making the OY1007 appropriate for demanding industrial environments where equipment is subject to rough handling or heavy workshop conditions. At a gross weight of approximately 11.5 kg — the heaviest in the family — it offers the most substantial build quality, which can contribute to greater stability during operation. Package dimensions match those of the OY1006 at 36 × 21 × 21.5 cm.

This pump is suited to applications requiring the longest continuous hydraulic working cycles, such as large-bore cylinder actuation, extended structural bolting sequences, industrial pressing operations, or any task where frequent oil-level interruptions would disrupt workflow. For professional hydraulic tool users in heavy industry, construction, and infrastructure maintenance, the OY1007's combination of maximum reservoir volume, high-pressure output and durable steel construction represents a high-endurance solution in the pneumatic pump range.
