Product description The VIAIR 400C Electric Air Compressor is a 33% duty cycle compressor that works quickly and efficiently, putting out 2.62 CFM/12V and 2.33 CFM/24V flow at zero PSI head pressure. Features include a standard 1/4in. NPT stainless steel braided leader hose with inline check valve and insulated wiring for simple installation. Amazon.com Viair's 40040 400C Air Compressor Kit is built around their 400C model air compressor. Rated at 150 PSI, the 400C is a 33% duty cycle compressor that works quickly and efficiently putting out a massive 2.54 CFM flow at zero PSI head pressure providing a powerful foundation to build out an air compression system. The 400C features an oil-less, no maintenance design, with a gearless direct drive permanent magnetic motor, heavy duty PTFE piston ring and precision and high-speed durable bearings for increased piston and motor life. Additional parts provided with the kit include: mounting hardware, heavy duty mounting feet with vibration isolators, freeze-resistant wiring, remote mount air filter assembly, air line for remote mounting air filter, heavy duty terminals (spade connector, ring terminal) and more. .caption { font-family: Verdana, Helvetica neue, Arial, serif; font-size: 10px; font-weight: bold; font-style: italic; } ul.indent { list-style: inside disc; text-indent: -15px; } table.callout { font-family: verdana; font-size: 11px; line-height: 1. 3em; } td.vgoverview { height: 125px; background: #9DC4D8 url(https://images-na.ssl-images-amazon.com/images/G/01/electronics/detail-page/callout-bg.png) repeat-x; border-left: 1px solid #999999; border-right: 1px solid #999999; padding-left: 20px; padding-right: 20px; padding-bottom: 10px; width: 250px; font-family: verdana; font-size: 12px; } 150 PSI with a Massive CFM Flow VIAIR 400C compressors are used at the center of a fully functional onboard air system and are rated to 150 PSI maximum working pressure with 33% duty cycle, meaning that the unit is able to be operated up to 15 minutes, and allowed to rest for 30 minutes thereafter before restarting (based on a 100 PSI, 72° Fahrenheit environment). Features include a standard ¼" NPT stainless steel braided leader hose with inline check valve and insulated wiring for simple installation. 150 PSI with a massive 2.54 CFM flow at zero PSI head pressure.

Duty Cycle is commonly expressed in percentile as: compressor on time (compressor on time + off time) %. As an example, a compressor that is rated for 25% duty cycle means that compressor can be operated at: 100 PSI @ 72°F for 10 minutes on and 30 minutes off. 10 min. on / (10 min. on + 30 Min. off) = 10 min. / 40 Min = 25% duty cycle. 1-Year Limited Warranty VIAIR Corporation warrants this product, when properly installed and under normal conditions of use, to be free from defects in workmanship and materials for a period of one (1) year from its original date of purchase.
