PA-1R has a portable design suitable for quick interventions. The system operates with oil-free pumps, making the maintenance of suction units easy due to its simple vacuum pump design. The system’s 2-liter transparent jar makes cleaning and assembly easy, allowing users to see the liquid during operation. The simple design of the system also ensures ease of use. The system’s input power is 220-240V AC, and its frequency ranges from 50-60 Hz.  portable suction units can operate in environments where the temperature ranges from 0°C to 50°C. The pressure limits for the operating environment are between 0.49 atm and 1.0 atm, and the optimum humidity is between 30% and 70%. A hydrophobic filter is essential to prevent liquid from entering the pump system in portable suction units.
