VIAIR support FAQ

Common questions about manuals, registration, and support for this brand.

  • Must the vehicle engine be running when using a VIAIR portable compressor?

    Yes, for most portable 12V VIAIR compressors, it is essential to have the vehicle engine running during use to ensure the compressor receives sufficient power and to prevent draining the vehicle's battery.

  • Is it safe to exceed the recommended working pressure?

    No. To avoid bursting or damage to the unit, never exceed the recommended maximum inflation pressure or working pressure specified for your VIAIR compressor model.

  • How do I clean my VIAIR compressor?

    Use a clean, damp cloth with mild soap to wipe down the exterior. Do not use liquid cleaners or submerge the unit in water, as it is moisture-resistant but not waterproof.

  • Does VIAIR offer a warranty?

    Yes, VIAIR Corporation generally warrants its products to be free from defects in workmanship and materials for a period of one year from the date of purchase. Original proof of purchase is required.
