Master Flow

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

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.

WARNING: Cancer and Reproductive harm-​

What is DEHP?
Di (2-ethylhexyl) phthalate (DEHP) is a plasticizer used to make PVC soft and flexible. DEHP is the world’s most widely used PVC plasticizer and is used in virtually every category of flexible PVC.
Where is it used?
DEHP is used in a wide range of soft PVC products ranging from medical devices such as medical tubing
and blood bags, to footwear, electrical cables, packaging and flooring.
Why is it used?
Plasticizers are essential to make PVC flexible. PVC is rigid by nature but plasticizers are added to allow the tubing to become flexible and expandable, while retaining its shape. DEHP is widely used because it is low cost, processes well and has provided good end use performance.
