TOP 12 Best Air Compressors for Garage and Workshop

The market is full of compressors for a range of domestic and industrial applications. For a garage, change house, home workshop and small production, electrical reciprocating compressors as the most optimal in terms of price-performance ratio. The unit produces compressed air, which will pump up the wheels, pool, boat, mattress, blow through the fuel system, remove debris from hard-to-reach places, for example, between tiles in the yard. With various attachments it will turn into a miniature sink, sandblaster, paint sprayer and pneumatic tool.

The rating contains small universal piston compressors of 25-50 liters, suitable for a car workshop, garage or repair work. We figure out which compressor is better to choose oil or oil-free, the advantages and disadvantages of each.

In the country and in the house, the compressor will also find wide application. A nail gun is connected to it - it is easily operated with one hand, an impact wrench, an air screwdriver, a variety of machines with pneumatic clamps. For correct and long-term operation of tools and attachments, it is necessary to select the correct type and power of the compressor.

How to Pick a Good Air Compressor

Domestic air compressors differ in design, power, capacity, air volume and other characteristics.

Oil Compressors require the filling of oil into the crankcase, which is involved in the process of air injection. They are productive, durable, can work for a long time without interruption. Of the minuses: they need periodic replacement and topping up of the lubricant, there are oil particles in the pumped air, so it is not suitable everywhere.

Oil-free reciprocating compressor does not need lubrication, which means it is easier and cheaper to maintain. These units are more compact than oil units and provide the consumer with clean air without impurities. With cooling, durability and reliability in such devices, not everything is clear. Despite the use of Teflon with a low coefficient of friction, the mechanics wear out faster than in oil models. Their working hours rarely exceed 15-20 minutes per hour.

An oil compressor, as a rule, is more powerful than analogues and lives much longer. It is advisable to use them where long-term operation of the apparatus is required (small-scale production). It is good for painting - unlike oil-free, it does not bubble, providing uniform and beautiful layers.

The oil-free unit is good for the garage and workshop: for inflating tires, connecting pneumatic tools, including gas sensitive to purity. It is easy to maintain - no need to add oil.

Operating pressure

Specified in bars or atmospheres - the pressure units are identical. The characteristic is important for pneumatic tools and various accessories and must exceed the values ​​indicated on them. The data below is given as a guideline, when purchasing a compressor to work with some tools, be interested in the pressure necessary for its functioning and add 1-2 atmospheres for the future.

Receiver - a metal cylinder where air is pumped. The volume of the receiver determines the duration of work between pumping and the preparation time of the device for operation - filling the receiver from scratch.

Tool performance. Air compressor performance is the volume of air that it can pump in 60 seconds. Indicated for operation in normal conditions, the device is selected based on the desired maximum plus 30-50% in reserve.

Which compressor to choose for pneumatic tools?

Decide on the tools to be connected before purchasing. Their total consumption must be ~ 25% lower than the device's performance, otherwise it will work close to the limit of capabilities and quickly fail. A fair amount of 50-80% is also not needed. For household and most professional tools (nut, screwdrivers, drills), a pressure of 6-8 bar is sufficient, which means that the unit must pump 8-10 bar. The volume of the receiver depends on personal preference and specific cases. With a large tank, the motor turns on less often and runs longer; before operation, it builds up working pressure for a long time.

How to choose a compressor for car painting?

For an airbrush and a spray gun, an oil-free compressor is needed; when operating an oil compressor, filters and oil catchers are required. The remaining parameters depend on the characteristics of the spray gun, and 20-30% must be added to them. A household device with a pressure of up to 5-6 bar will cope with painting work.
