Oil-Free Piston Pump
The 7A 45D uses an oil-free piston pump, providing suction without the need for routine oil addition. According to the supplied product description, this design avoids oil and smoke pollution during operation.
Adjustable Negative Pressure
The suction apparatus allows negative pressure to be selected according to the application. The supplied specifications list a maximum vacuum of 90 kPa and a maximum negative pressure value greater than 0.09 MPa.
Dual Glass Jar System
The unit incorporates two glass jars, with the supplied specification listing 2500 mL for glass jar/reservoir capacity. An overflow protection mechanism is included.
Hand & Foot Switch Operation
The Medinain 7A 45D provides both hand-switch and foot-switch controls, allowing convenient operation during suction procedures.
Four-Wheel Mobile Design
The apparatus is equipped with four wheels, making it suitable for movement within healthcare environments. Its specified dimensions are 400 × 355 × 600 mm (L × W × H).
Backflow Protection
The supplied product description states that there is no backward-flow pressure when the machine stops, helping prevent collected liquid from flowing backward through the suction system.
