PURPOSE: An air-type vacuum suction device is provided to obtain recyclable waste cutting oil through a suction and discharge process by separating chips form the waste cutting oil. CONSTITUTION: An air-type vacuum suction device comprises a first air suction line(10), a vibration generating unit, an oil suction line(30), a chip filtering container, and an oil discharge line(40). The first air suction line inhales compressed air. The vacuum passage of the vibration generating unit induces a vacuum state by the flow of the compressed air. The oil suction line sucks the waste oil containing foreign materials using the vacuum sate. The chip filtering container filters the foreign materials in the waste oil. The oil discharge line discharges the waste oil filtered by the chip filtering container to the outside.
