3 Things to Look for When Choosing a VMAC

While offering a range of unique benefits, rotary screw compressors also come with a steep price tag. Though larger systems may be cost-effective even with a rotary compressor, the cost of these high-tech instruments can be a serious hindrance when working with smaller systems such as vehicle mounted air compressors (VMACs), which are often housed in trucks.

Traditional reciprocating piston compressors and rotary screw compressors are both viable options for vehicle mounted applications. But these models have unique, distinct features, often making it difficult to choose between the two.

Below are three key considerations to keep in mind when selecting the best type of VMAC for your specific application.

1. Size and Weight of the VMAC

VMAC RaptairFuel cost is a key consideration when budgeting for VMACs, and a lighter compressor can offer significant cost saving advantages. In fact, a 200-lb reduction in weight can result in fuel cost savings of 4%. This also allows the application to be free of stringent DOT regulations.

Rotary screw compressors are clearly the best option in this regard, as they are lighter than piston compressors of the same rated capacity. Rotary screw models are time-tested, and can be expected to operate reliably for long periods of time. They also allow for consistent air delivery, which means receiver tanks are unnecessary in most applications.

2. Continuous Air Power

In any type of job, an interruption in supply will result in increased downtime and higher costs. Therefore, it’s essential that the compressor chosen can provide a continuous air supply, which will allow jobs to be completed at the fastest rate possible — thereby enhancing customer satisfaction and upping the number of projects that can be finished in a given time frame.

In this regard, rotary compressors are superior to traditional reciprocating piston compressors. For example, the RAPTAIR-G30 model offered by Compressed Air Systems provides continuous 30 cfm air flow, as well as a 100% duty-cycle rating. This translates to continuous operation and a continuous compressed air supply; the air tools can be employed continuously, and no time is wasted due to lack of compressed air availability.

3. Cost

Naturally, cost is a critical consideration when choosing one type of compressed air system over another. Cost is arguably the most important factor in any type of commercial project. However, it’s essential to maintain a balance between quality performance and cost investment.

For example, traditional rotary compressors, though reliable and time-tested, come at a very high price. As an alternative, the VMAC G30 is the most affordable gas driven rotary screw air compressor available. It offers the power and performance of a rotary screw air compressor, but at a more affordable cost,  close to the price point of a reciprocating air compressor.
