Features and benefits

  • Inflate or deflate up to 4 tires simultaneously and automatically up to 145 psi.
  • Wall-mounted unit equipped with 4 air hoses of 8’ / 2.4 m.
  • Only 4 min. 12 sec. to inflate 4 x 11R22.5 tires from 0 to 100 psi / 6.89 bar. 
  • Loud audible signal warns that the tires have reached the desired pressure.
  • 4 measurement units (psi, bar, kPa, kg/cm2), Over pressure system, LCD screen & backlight.

One, two, three or four tires can be inflated or deflated at the same time with the Flatematic 4 way. Once connected to the valves, the tire inflator will automatically start inflation or deflation to precisely reach the identical pressure for all tires. Its higher airflow ensures the same great efficiency when inflating 4 tires than the other automatic tire inflators of the Flatematic series. All four hoses are equipped with clip-on chucks making tire inflation more productive by allowing you to work away from the tires. 

*Air compressor required

Important: compressed air contains water and oil, use proper air filter between the source and device. Failure to do so will void the warranty.

  • Do I need an air compressor with my inflator?
    Yes, the inflator does not produce compressed air.

  • What kind of air compressor should I use with this product?
    The compressor should
    have a stable air supply monitored by an air regulator (maintain a minimum air pressure fluctuation)
    be equipped with an air filter to protect against water and oil contained in compressed air.
    meet the minimum and maximum air inlet pressure of the inflator.

  • Can the inflator be installed outside?
    No, the inflator is not intended for prolonged outdoor use. Its Ingress Protection (IP) rating is 66.

  • Can I use the Flatematic 4way with fewer than 4 tires?
    Yes, you can use the Flatematic 4 way with 1, 2, 3 or 4 tires.

  • Can I select different tire pressures for each tire inflating at the same time?
    No, the final pressure needs to be the same for all tires.

  • Can I inflate tires to the same final pressure that do not have the same starting pressure?
    Yes, the Flatematic 4way will automatically send the correct air pressure into each tire until they all reach the same final pressure.

  • Can I start inflating one tire and connect another tire during the inflation process?
    Yes, simply connect your other tire. Note that all tires will finish inflating at the same time.

  • My tires are all connected to the air hoses but the inflator doesn’t automatically start. What is wrong?
    1. Make sure the manifold is properly purged. Refer to manual for the procedure.
    2. If tire pressure is less than 3 psi, the inflation needs to be manually started. (refer to the manual)

  • Do I need to recalibrate my inflator?
    No, the inflator has an automatic calibration feature. It recalibrates itself every time it starts.

  • Can I use another type of chuck on my inflator?
    Yes, other chuck types can be used. However, the chuck type installed on the inflator must be respected. In this case it is a closed chuck. The chuck must also remain in place without someone holding. (clip on chuck, screw on chuck, etc.)

  • What maintenance service do you offer?
    MARTINS offers Maintenance and calibration service (MW-MC) in addition to its 1 year warranty.
