VIAIR CORPORATION

VIAIR portable air compressors are available in 12V DC and 24V DC configurations. Models such as the 207CF6 (12V DC, 23.0 A) and 207CH0 (24V DC, 6.0 A) illustrate the range. The voltage choice depends on the vehicle or system electrical architecture; 12V units are common in automotive and light-truck applications, while 24V units suit heavy-duty trucks, military vehicles, and industrial equipment. Current draw varies proportionally, with 12V models typically drawing 19–38 A and 24V models drawing 6–15 A.

Yes, all VIAIR portable air compressors listed by 3G Electric are oil-free. This design eliminates the need for oil changes, reduces the risk of oil contamination in the air stream, and allows operation in any orientation. Maintenance is limited to periodic air filter replacement (where applicable) and checking electrical connections. The oil-free construction also makes these units suitable for applications where oil mist is undesirable, such as inflating air suspension systems or operating pneumatic controls.

Flow rates vary by model. At 90 psi, output ranges from 0.51 cfm (model 207CH0) to 1.41 cfm (model 207CK9). At higher pressures, such as 150 psi or 200 psi, flow rates are lower—for example, 0.29 cfm at 150 psi for the 207CH0 and 0.51 cfm at 200 psi for the 207CF6. These specifications allow selection based on the required duty cycle and tool consumption. Tankless models provide intermittent flow, while tank-equipped models (2-gallon) buffer demand for short bursts.

Both configurations are available. Tankless models (e.g., 207CH0, 207CM0, 207CJ5, 207CK9, 207CH3) are compact and lightweight, suitable for portable inflation and intermittent use. Tank-equipped models (e.g., 207CF6, 207CF5, 207DG3) include a 2-gallon horizontal tank, which stores compressed air for higher instantaneous flow and reduces compressor cycling. The tank also allows operation of air tools for short periods without continuous compressor run time.

Included accessories vary by SKU. Common items are leader hoses, safety valves, drain cocks, pressure switches, air filters, spare air filter elements, carrying bags, and mounting hardware. For example, the 207CF6 includes a safety valve, while the 207CK9 includes a carrying bag. These accessories facilitate installation, operation, and maintenance. Specific inclusions are listed in the product specifications for each model.

Yes. While VIAIR compressors are commonly used for tire inflation and air lockers in off-road vehicles, their oil-free, DC-powered design makes them suitable for industrial applications where AC power is unavailable or impractical. Examples include powering pneumatic controls in remote equipment, inflating industrial bladders, operating small air tools in field maintenance, and providing compressed air for air suspension systems in material handling equipment. The quiet-rated models (below 75 dBA) are also appropriate for noise-sensitive environments.
