PORTAIR Series Mobile Air Compressors PORTAIR series mobile air compressors are ideal solutions for the applications in construction, mining and naval engineering sectors. These compressors, which are built with high endurance, quality and performance grades rotary screw blocks, offer long maintenance intervals, high performance, high airflow capacity and large gas tanks comparing to the competitors so that they can be used at any remote place where compressed air is needed. ROTARY SCREW BLOCK • New generation rotary screw blocks, designed with latest technological tools like "Computational Fluid Dynamics (CFD)" and "Finite Element Method (FEM)" and manufactured using high-end manufacturing techniques, provide high efficiency, durability and low energy consumption with new rotor profile and lobe combination. • Block contains new generation bearing system in which the bearings with three times more load carrying capacity than the standard • As new rotor profile permits less air leakage occurrences with optimal lobe combination and decreases the torque needed to operate, less energy is needed to operate that leads to less operating costs. • Gearboxes are chosen with respect to AGMA (American Gear Manufacturers Association) standards. (PA 50 & PA TOO) GENERAL FEATURES • With high airflow capacities, PA 34 and PA 50 allow up to two, PA 64 allows three and PA 100 allows four pneumatic breakers connected and operated at the same time. • PORTAIR series compressors have the type-approval certificate in accordance with EU 2007/46/EC framework directive. • Adjusting the airflow capacity with respect to instantaneous air demand by controlling diesel engine and rotary screw block provides fuel savings and thus the operating costs are minimized. • Crucial information such as outlet pressure, fuel level and operation time can be observed on the control panel consisting of electronic control card as well as the alarms such as high engine and compression temperature, low battery, low fuel, service request and • Working without any performance loss in challenging environments is realized thanks to its canopy durable against corrosion and impacts. • Maintenance doors placed at sides provide easiness while reaching any part underneath the canopy. • By employing direct-drive mechanism instead of other classical transmission alternatives, power transmission losses are minimized so that more compressed air can be produced with less fuel consumption.

PORTAIR Series Mobile Air Compressors MAIN MOTOR AND DRIVE SYSTEM • KUBOTA's four-cylinder, water-cooled and turbo-charged (except PA 34) diesel engines are employed as a standard in PORTAIR series mobile air compressors. • PORTAIR series compressors cohere with the emission standards with their diesel engines having lowest exhaust emission levels in their class, (except PA 7 00) • Driving the rotor shaft (gearbox shaft in PA 50&PA100) is realized by direct-drive mechanism with a flexible coupling placed between rotary screw block and main motor shaft. • As the mechanical transmission...
