Tire Inflator, Twin Cylinder, MF-1089 Diabloww, 45AMP, 5500 Cu In

Twin Cylinder Portable Diabloww MF-1089 12v Tire Inflator - Masterflow

CONVENIENCE: The MasterFlow MF-1089 Diabloww air compressor gives twice the punch with dual 30mm pistons powered by a direct drive, 12-volt motor. The MF-1089 twin cylinder tire inflator provides an astounding 5500 cubic inches of air flow per minute. Powers directly from your battery by a 10 foot heavy duty power cord and alligator clips. Includes a 24 foot self-coiling air hose with quick connect air fittings. The air hose is equipped with an armored in-line air gauge, easy twist brass inflator, and optional clip-on air chuck.

MULTIPLE USES: This unit is great for in the truck, off the road, or anywhere you need air quickly to get the job done. The MF-1089 tire inflator is also great around the farm or ranch, and can be used to inflate even the largest agricultural tires. Includes a heavy duty nylon carry bag, two adapter nozzles, and a ball inflation needle. For off road enthusiasts that air down when they hit the trails, we recommend using the MF-1089 for 35 inch tires and over to get back on the black top. Full size truck tires can be inflated from 25-35 PSI in under 1.5 minutes and a passenger car tire in under a minute. Inflation times may vary based on environmental conditions. Be safe by being informed, research and understand the proper operating pressure for your tire and vehicle combination.  Proper tire inflation can extend your tire’s tread life.

EASY TO USE: Alligator clips are easily and quickly attached to your vehicle battery. The duty cycle for this compressor is 40 minutes on, 40 minutes off. Plenty of time to air up 8 tires to get you and a buddy back on the road. 16 ft hose gives you plenty of room to work with.  Includes a convenient nylon carry bag, two adapter nozzles, and a ball inflation needle.

GREAT GIFT IDEA: Diabloww is the devil of compressors! Anyone in your life that has larger size tires will thank you for this gift.

Customer Reviews

No customer service

Attempted to contact customer service on several occasions regarding a recent purchase and did not receive a company response. The only reason I am giving one star is that I cannot give a lower rating. You better be happy with your purchase, because there is no recourse. I now see why people buy from Amazon where you have some recourse with the seller. My next step is th file a complaint with my credit card company. DO NOT BUY FROM THIS COMPANY!

Best portable compressor

AS advertised, quite powerful and fast. Filled standard SUV from 20 psi to 40 psi in less than 1 minute.

Amazing Value & performance

Being in construction and pulling lots of trailers I wanted a small air compressor in my truck for airing up low tires. I hard mounted the Diabloww in my side toolbox and mounted a 2.5 gal air tank under the truck. Fills tank to 120 psi in 2 min 15. Perfect little compressor I highly recommend it


Appears to be a robust unit. Upon receipt several bolts were slightly loose and one in the foot support was totally backed out but no big deal. Pumped up 70psi truck tire in no time and is way quieter than I was expecting.

A beast

Fabulous so far
