The air-operated oil aspirators are ideal for a rapid changing of motor oil to every vehicle. The recovery of the exhausted oil is carried out for fall, through the lateral basin adjustable for height, and also through aspiration thanks to the probes. After depressurization they work autonomously, without the need to be connected to compressed air, for an independent and quick aspiration, using the suitable probe between the included kit of 10 probes. The units can suction till 2/3 of their capacity. Change the oil at a temperature of 60°- 80°C (when the engine is just switched off). Warning: do not use these units for the suction of brake oils, fuels and inflammable liquids
