The air filter is reusable. However, if the filter (part number 2Y30QJ03) becomes damaged a new one can be purchased.
This air compressor is compatible with any 1/4" or 3/8" diameter air hose. As long as the hose has a 1/4" plug on one end of the air hose to fit into the 1/4" universal coupler supplied on this air compressor.
Senco compressors are manufactured in the USA. at their plant in Hutisford, Wisconsin. I have (3) of the 1 gallon 1/2 HP compressors. 1 in each truck. My Technicians love them. They are light wait, very quite and refill quickly. If you are doing trim work they are perfect.
It is steel, a good light weight compressor, easy to carry.
In my opinion, if you are looking to fill up a tire (do you mean a vehicle tire from flat?) on a constant basis like daily, then this unit is not the one for you. I would recommend a much larger capacity, in the range of at least 10 gallons. If you are just topping off vehicle tires with maybe an occasional fill from flat, then this will do the job although it will take time for the flat fill. But for the price, it's a good bang for your buck.
Yes, this model is compatible with nailers.
Pump turns off at 130 lbs. on start-up and refills to that pressure on demand. Good compressor for baseboards etc, not good for car tires (too slow). Weighs almost nothing and very quiet compared to my last and larger capacity Dewalt.
