Piston compressors — BM-50VP example — Xinlei Compressor

Datasheet

Product overview

Power: 2 hp (BM-50VP) · Pressure: 8 bar (BM-50VP)

Xinlei's direct-drive piston range combines a piston compressor with an integral motor-driven arrangement and includes receiver-mounted versions for portable and workshop air duties. The BM-50VP product page and its linked piston catalogue show a vertical receiver with a wheeled frame, pressure-switch assembly, regulator and outlet connection. These details help distinguish a tool-air package from a bare compressor pump.

The catalogue's BM-50VP example is identified as ZB-0.1/8-BM-50VP: 50 L receiver, 230 V supply, 50 Hz, 2 hp motor rating, 2850 rpm and 8 bar working pressure. It lists 196 L/min as theoretical displacement. That number must not be treated as delivered free-air flow at 8 bar. The same catalogue lists BM-16F and BM-75VP examples with 16 L and 75 L receivers and the same stated 196 L/min theoretical displacement, illustrating why tank size is not compressor flow.

For a pneumatic tool, compare the tool's air consumption at its specified pressure with the compressor's delivered flow at that pressure. A receiver can buffer short peaks, but the permitted duty cycle and recovery time determine whether the machine can support repeated or sustained work. Ask for measured delivered air, start/stop settings, allowable running time and restart behavior rather than sizing from receiver litres alone.

The regulator changes outlet pressure; it does not make the compressor deliver more air. State the tool or process, working pressure, air consumption, peak duration, simultaneous users, hose length, and whether oil or moisture in the air matters. For spray work or other sensitive uses, identify the required filtration and drying instead of assuming the receiver-mounted package contains them.

Request the exact current model, voltage/frequency and plug arrangement, receiver documentation, included accessories, maintenance instructions and local service-parts availability. The values above belong to the published BM-50VP catalogue example; alternative sizes and electrical versions should be quoted as their own configurations.
