Oil-Free Piston Pump
The Medinain 7A 25D uses an oil-free piston pump, eliminating the need for routine oil maintenance. According to the supplied product information, the pump operates without oil or smoke pollution.
Adjustable Negative Pressure
The suction apparatus allows the operator to select negative pressure according to the application. The supplied specifications list a maximum negative pressure value greater than 0.09 MPa and a maximum vacuum of 90 kPa.
Dual 2500 mL Glass Jar System
The unit is equipped with two glass jars and a specified 2500 mL glass jar/reservoir capacity. An overflow protection mechanism is included as part of the suction system.
Hand & Foot Switch Operation
The Medinain 7A 25D includes both hand-switch and foot-switch controls, providing convenient operating options for healthcare personnel.
Mobile Four-Wheel Design
With four wheels and dimensions of 400 × 355 × 600 mm (L × W × H), the apparatus is designed as a mobile suction unit for healthcare environments.
Backflow Protection Design
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.
30-Minute Continuous Working Time
The specified maximum continuous working time is 30 minutes, with a continuity rate of 50%. Operation should remain within the manufacturer's specified duty cycle.
