VIAIR 85p Portable Air Compressor Review


  • The performance can be quite depressing as it isn’t stable as the stationary one found on the market. It is to be less powerful. The pressure range of the 85P series’ tops out at 60 PSI, & it is only capable of re-inflating 31 tires. In case of power lacking, the unit makes it up for available accessories.

VIAIR 85P metter


Where are Viair compressors made?

The factory is in China, ISO certified, and the produced compressors are CE certified. The company fixes the materials in the U.S.

Is it possible for a tire to lose air without any hole?

Yes, it is possible. Just because your tire looks beautiful does not mean there isn’t any way to escape the air. There are two possibilities: the wheel & the valve stem for mounting the tire.

How big should be an air compressor to fill a car’s tire?

PSI is enough for most of the car’s tire 32-35. A portable compressor of 1 or 2 CFM at 90 PSI would be the right choice for accomplishing the job.

What should be the size of an air compressor for an impact wrench?

Usually, a 4-5 CFM compressor at 90 PSI suits an impact wrench of ½ inch best.

 I could recommend one more thing, i.e., look for a compressor having a capacity of 20 gallons. Such a function of a gallon will avoid the delay between the tasks.

What are the disadvantages of VIAIR 85P?

Unfortunately, you have to bear some adverse effects too. As per the negative report of the customers, the unit blows a fuse on the car. The maximum ampere draw is 14.5 amps.

So, to avoid such an accident, make sure to check the power-port rating for your car’s max amperage before ordering the product. Bear in mind that your car engine should be running at 85P.

 It will be safe to directly use an adaptor (like Roadpro 12-volt) to connect the compressor to the battery.

Bottom line

Hope you understand from VIAIR 85P review, that this compressor is something that every car owner should consider keeping for emergency cases. But if you are looking for a multifunctional one, then find something more substantial and with the extra powerful unit. This stuff can only re-inflate flat-tires though some of the users have commented that the material is also able to inflate the air mattress.
