VMAC Above Deck Air Compressor
Predatair 60 Specifications
SPECIFICATIONS AT A GLANCE
SizeSize is definitely a feature that buyers look at. Trucks are used for more diverse applications and often have more than one function that means payload space is used for toolboxes, cranes, welders and other equipment. Limiting the size of an above deck compressor means more room for all the other pieces fleet managers require. The PREDATAIR60 takes advantage of the compact VMAC VR70 compressor. The VR70 offers a large amount of air in a very small package. Coupled with other parts chosen for durability and size, the PREDATAIR60 is very small indeed. The compressor is mounted horizontally above the tank and is direct coupled to the hydraulic motor. A common bracket holds these components and maintains a rigid structure. The absence of a belt keeps the package free of any externally moving parts. Assembly of the components is designed to be as compact as possible without taking away from performance. MaintenanceBy keeping to the base VR70 compressor, VMAC is not limited to existing, bulkier encapsulated compressors. The PREDATAIR60 will produce 60CFM in a package sized smaller than most 35-40 CFM products currently available. Length and width are 3 inches less than the closest competitor's 40CFM unit. The major obstacle to any further size reduction in the overall package is the cooler itself. CoolingCooling issues plague hydraulic above deck compressors and cause compressor shut-downs on a regular basis. Most hydraulic driven air compressors need large hydraulic reservoirs to help disperse heat from the hydraulic oil and sacrifice hydraulic cooling for increased air compressor cooling. The VMAC VR70 compressor is more than capable of operating at temperatures up to 270 degrees F. In underhood applications the compressor shuts down when the compressor temperature reaches 280 degrees F. VMAC anticipates that the PREDATAIR60 compressor will run hotter than ompetitors' products that use encapsulated third party units that have temperature shut-offs near 180 degrees F. By operating the compressor in a higher temperature range, more cooling can be dedicated to the hydraulic oil. Given that all hydraulic pumps in the market run at different efficiencies and possibly have years of wear, the PREDATAIR60 is designed to handle 100% duty cycle and keep both hydraulic and compressor oil within temperature specifications. The ultimate goal is to work harder at cooling the hydraulics and limiting the size of the reservoir that may be required. To VMAC, anything required for operation of the PREDATAIR60 must remain as small as possible to meet demands of customers and keep payload usage to a minimum. MaintenanceMaintenance is also a major concern. VMAC has strived to make routine maintenance as easy as possible. Every filter, the oil drain and oil fill as well as the air pressure regulator on the compressor are accessible without removing a cover. This will mean less time spent on maintaining the unit. As well, general maintenance items are common with VR Underhood compressors. Existing dealers won't have to stock different filters or oil when they choose the Predatair to complement the Underhood system in their product line. Unlike most competitors, the PREDATAIR60 will not have a belt to maintain. The direct drive technology used on the Lincoln AirVantage 500's compressor built by VMAC is the same technology used in the PREDATAIR60. Lincoln recognized the benefits of direct drive and the durability of this technology. The gear cover will be a standard SAE B 2-Bolt flange face that will accept a standard hydraulic motor. The compressor will couple direct to the hydraulic motor. Although an SAE A Port would have made for a smaller package, the B Port adds strength and longevity. In case of an unlikely failure to the hydraulic motor, an off-the-shelf unit can be easily used for a replacement. |
