Dual use brake fluid for hand and air, replace engine

The dual-purpose brake oil replacement machine is a one-on-one equipment for auto repair and maintenance, with manual/pneumatic dual modes. One person can complete the fully enclosed replacement of the car brake oil, bidding farewell to the traditional dual person brake oil release. It is effective, clean, and less prone to air ingress.

The body is lightweight and portable, with a compact structure, equipped with handles or casters, making it convenient for workshop and on-site service.

. Adopting a dual power design of manual and pneumatic pressurization: when there is no air source, use a manual pump for pressurization; When there is an air compressor connected to the pneumatic interface, the pressure is stable and the oil change is fast.

The equipment is equipped with a built-in pressure regulator (adjustable from 0-4bar), a new/old oil dual transparent pot, oil resistant and anti-corrosion (based on actual reports) pipelines and speed suitable joints, compatible with DOT3/DOT4/DOT5.1 brake oil, covering 90% of passenger vehicles.

. The working principle is equal pressure and equal displacement: the new oil is pressurized and pushed into the master cylinder, and the old oil is synchronously extracted from the sub cylinder, with a fully enclosed circulation to avoid oil droplets and air mixing. After oil change, there is no need for secondary exhaust, and the brake is more sensitive and safe.

Manual mode: No power/air supply required, pressure can be generated by pressing, suitable for emergency, outdoor, and small batch oil changes.

. Pneumatic mode: connected to an air compressor (2.5-8kg/cm ²), with stable pressure and uniform flow rate. Four wheels can operate simultaneously, increasing efficiency by three times.

Equipped with multiple specifications of one-to-one connectors, quick disassembly and assembly, and no oil leakage; Equipped with overload/low voltage protection, anti slip and anti suction air intake; The old oil pot is sealed and leak proof, environmentally friendly and easy to clean. Single person operation takes about 8-10 minutes to complete the entire vehicle oil change, thoroughly removing old oil and impurities from pipelines and ABS pumps, and extending the service life of the braking system. It is a practical tool for auto repair shops, fleets, and DIY maintenance.
