Airdog Manuals & User Guides

The Airdog brand category on Manuals.plus encompasses user guides and installation manuals for two separate major entities sharing the name.

• PureFlow AirDog (Automotive): Specializing in diesel fuel delivery systems, PureFlow AirDog manufactures the Raptor-4G and AirDog II-5G series. These fuel air separation systems and lift pumps are designed to improve engine performance for diesel trucks (Chevy Duramax, Dodge Cummins, Ford Powerstroke) by removing water, particulates, and entrained air from the fuel.
• Airdog USA (Home Appliances): A silicon valley-based company producing washable, filter-less air purifiers such as the X3, X5, and X8 models. These units utilize patented TPA technology to eliminate pollutants and viruses without the need for disposable HEPA filters.

Please ensure you select the manual corresponding to your specific automotive fuel system or home air purification device.

• What is the difference between the Airdog products listed here?

  This category includes manuals for two distinct product lines: PureFlow AirDog diesel fuel systems (lift pumps and air separators for trucks) and Airdog USA home air purifiers (electronic air filtration units).

• How do I register my PureFlow AirDog warranty?

  Warranty registration for fuel systems typically must be completed within 30 days of purchase via the official AirDog Diesel website to ensure coverage.

• Are Airdog air purifier filters washable?

  Yes, Airdog USA air purifiers use TPA technology with collecting plates that are designed to be washed and reused, rather than replaced like traditional HEPA filters.

• What is the preset pressure for the Raptor-4G fuel pump?

  For most stock applications, the Raptor-4G is preset at the factory (e.g., 8-10psi or 50-55psi depending on the model), but it features an adjustable regulator for performance tuning up to 75psi.

• Why is my Airdog air purifier making a zapping noise?

  Occasional cracking or zapping sounds are normal as the unit destroys larger particles. If the noise is constant, the collecting plates may need to be cleaned and fully dried.
